Field of the Invention
[001] The present invention relates to a filter element, especially an air filter element, for example, for filtering air in a motor vehicle, an agricultural or construction machine, with a retention geometry that allows a safe and space-saving arrangement of a filter element in an air filter housing. Fundamentals of the Invention
[002] Air filters are normally made up of an air filter housing and an interchangeable filter element. The filter element can be changed when it is loaded with dust after a certain period of service and when the filtration performance decreases. Normally, the filter element is replaced by the operator. In order to achieve an optimal filtering effect, it is necessary that the filter elements are integrated in the air filter housing in a reliable manner and in the exact position in order to make possible, in this way, an optimum flow geometry and, in addition, for obtain a reliable seal between a side of raw air and a side of fresh air. As the change must often be made by less qualified personnel, it is necessary to finish the filter element and the filter housing, which essentially prevents incorrect installation for this purpose. Filter elements are provided with retaining devices that make it possible to insert the filter element into the air filter housing and position it in such a way that reliable operation of the air filter is made possible. These filter elements are, for example, known from WO 2010/099317. There is described a filter element that can be inserted in an air filter housing. Synopsis of the Invention
[003] It can be considered as a task of the invention to offer a filter element, an air filter housing and an air filter that allow a safe operation positioning of a filter element within an air filter housing.
[004] According to the invention, an air filter element is offered to be inserted in an air filter housing, the air filter element offering an inflow face and a flow face, a means of filtration system and a filter element retaining device. The filter medium extends between the inflow face and the flow face, in an axial direction of the air filter element, the filter element retaining device being joined with the filter medium. The filter element retaining device has a retaining assembly that protrudes radially from the filtering medium, as well as a sealing assembly with a sealing line that surrounds the filtering medium. The radially protruding retainer assembly is located between the surrounding sealing line and the filter medium.
[005] In this way, the air filter element can be configured compactly, especially since outside the seal line it is no longer necessary to position other elements.
[006] According to an exemplified embodiment of the invention, the sealing assembly is suitable, by the combined action, for example, with an air filter housing, for the axial and / or radial sealing of the raw side (unfiltered air ) on a pure side (filtered air).
[007] According to another embodiment of the invention, the retaining assembly has an arc that protrudes radially. Preferably, the retaining set has several arches that protrude in a radial direction.
[008] According to an exemplified embodiment of the invention, the filter element has between the inflow side and the flow side at least one edge on which a first side of the filter medium and a second side of the medium reciprocally touch filtering. The filter element retaining device has radial arching at the edge, the sealing set having a sealing line that surrounds the filtering medium. The sealing line extends along the radial arc, and preferably, the radius R2 along the tracing of the sealing line is greater than the radius R1 of the edge. In other words, a sealing line extends over the radial arc.
[009] In this way, it becomes possible to offer a sealing path with a large radius compared to the internal edge radius of the housing. This allows for a simplified application of a sealing compound, for example, the insertion of a filter element, which in this way contains a sealing compound. In this case, the radial bending can essentially extend only on one side of the filter housing. Alternatively, the radial arch can also extend beyond two neighboring side faces of the filter housing, especially to an equal extent.
[0010] According to an exemplified embodiment of the invention, the retainer assembly has at least one bend in axial direction, the bend being configured to accommodate a projection on the side of the air filter housing. Instead of protrusions in the housing and bends in the filter element, partially or completely, protrusions in the filter element can also be provided, as well as bends in the filter housing.
[0011] In this way, the air filter element can be positioned exactly inside the air filter housing. In particular, the arching allows control over the correct insertion of the filter element in the housing. When the recess of the air filter element is cooperating with the protrusion of the housing, a correct mounting position will be present. When the recess and projection are not cooperating, this can be recognized directly, so that untrained personnel will also verify that a correct mounting position will not be present. The recess can be a transfixing or blind hole. The orifice may have a rounded circular cross section, however, it may also have an oval, ellipse or angular cross section.
[0012] According to another exemplified embodiment of the invention, there is a reduction in the cross section of the recess at least partially in axial direction. Especially, the recess protrudes axially at least in part, in a conical direction. In this way, the air filter element can be centered in the housing. In addition, assembly will be considerably simplified because the tapered shape requires less target accuracy when meeting the boss and the recess. The conical pipeline can be shaped like a cone, an obtuse cone or also a pyramid, that is, an obtuse pyramid. The conical adductor, however, is not restricted to a linear adduction, but can also have a curved adduction, possibly in the form of an obtuse parabola cone or an obtuse ellipse cone.
[0013] According to an exemplified embodiment of the invention, at least one of the recesses is an oblong orifice recess. In this way, a fixation with tolerances in relation to one direction can be achieved. This makes it possible to compensate for shock, ie vibration, or temperature. In addition, through an oblong hole, a twisted air filter housing can also be compensated to a certain extent. The combination of a conventional orifice and an oblong orifice allows - despite tolerance in the oblong orifice - a fixation in the exact position in the conventional orifice. It may also be envisaged to combine a conventional orifice with a first oblong orifice and a second oblong orifice that extends towards you. The variety of holes may be distributed under different points on the air filter element.
[0014] According to an exemplified embodiment of the invention, the retaining assembly has a variety of recesses in axial direction that are so positioned around the circumference of the retaining device of the filter element, that the recesses are distributed over an angle of at least 90 °. In this way, it can be ensured that the filter element according to the invention, which is intended for axial assembly, is not inadvertently replaced by a filter element for radial assembly. This increases the operational safety of the air filter.
[0015] According to an exemplified embodiment of the invention, the retainer assembly has a variety of recesses in axial direction, and the variety of recesses, referred to a central axis of the air filter element, has an angle division that defines a position unambiguous mounting of the air filter element inside an air filter housing. This way it can be ensured that the filter element, although selected correctly, is mounted in the wrong direction inside the air filter housing. As an alternative or complementary feature, the arrangement and / or configuration of the recesses can also serve for coding, that is, it will be avoided in this way, the assembly of a filter element of broadly identical construction, but even so, wrong.
[0016] Under the expression of angle division, angles must always be covered by two recesses in relation to a central axis. When the angles differ between different pairs of recesses, then, with a corresponding selection of the division of the angle, an erroneous rotational positioning of the air filter element within a filter housing is not possible. It should be understood that this position definition can also be achieved by a non-symmetrical arrangement of different recesses that do not match up with corresponding protrusions within the filter housing. Instead of projections in the housing and recesses in the filter element, partially or integrally, projections in the filter element can also be provided, as well as recesses in the filter housing.
[0017] According to an exemplified embodiment of the invention, the filter element retaining device has a sealing assembly with a sealing line that surrounds the filtering medium, the recesses being, at least partially, arranged between the sealing line surrounding area and the filter medium. In this way, the recesses can be provided within a sealing barrier. In this case, a recess in the form of a blind orifice that does not produce a passage between the side of the raw air and the side of the fresh air, however, keeps these regions separate. In addition, the external dimensions of the filter element can be kept reduced because a recess is no longer necessary outside the sealing line.
[0018] According to an exemplified embodiment of the invention, the recesses provided between the surrounding sealing line and the filtering element are closed recesses. In this way, the raw air side can be kept separate from the fresh air side.
[0019] According to an exemplary embodiment of the invention, the sealing assembly has an elastic sealing material, the sealing line being positioned on the sealing material. In this way, a reliable seal can be achieved that adapts to the crack to be sealed. The provision of a seal on the filter element ensures that a sensitive component of a seal, at each change of the filter element, is also replaced, always using a new seal. Otherwise, it would also be necessary to monitor a replacement seal in the event of a defect in a seal on the housing side.
[0020] According to an exemplified embodiment of the invention, the retainer assembly has a retaining face that is configured to transfer holding force between the air filter element and an air filter housing, the retaining face being disposed between the surrounding sealing line and filter medium. In this way, axial positioning of the sealing element can be ensured. The positioning inside the seal furthermore limits the measure of construction of the filter element, because in the outer radial position of the seal it is no longer necessary to provide other surfaces.
[0021] Advantageously, the retaining face is arranged in an axial direction out of relation to a sealing face, facing in the same direction, and which consists of a sealing assembly on the side of the filter element. For example, an axially offset retaining face stands out for the advantage that by axial offset it can be avoided that when molding the seal assembly to the retaining assembly, sealing mass may reach the retaining face. Furthermore, it is advantageous from a technical point of view when the corresponding retaining face and seal on the sides of the filter housing are arranged at the same height. As the retaining face on the side of the filter element is axially recessed in relation to the sealing face facing in the same direction, a definite compression of the seal is ensured.
[0022] Due to the especially secure operation of the air filter element inside the filter housing, an extension of the invention stands out, in which the retaining assembly, on opposite sides, presents a retaining face positioned between the seal and filter medium. The retaining faces are therefore facing in opposite directions, and are also configured to touch the retaining faces on the filter side of the filter housing. The filter element can be kept safely operational and in the exact position in both axial directions.
[0023] According to an exemplified embodiment of the invention, the path of the sealing line, in segments, is curved towards a radial distance from the filtering medium. The spacing curvature by segments represents, in the direction of view, lateral over the filter element, a concave bending line. A recess in this way makes it possible to position other construction elements, such as, eventually, a reinforcement rib, a prop, or a screw, or similar unit.
[0024] Through an especially uniform path, an example of the invention stands out, in which the sealing line extends along several segments of the filtering medium in a curved direction of radial clearance, being that for each segment of curved path in spacing a segment is allocated, in which the sealing line protrudes radially curved in the direction of the filtering medium. A filter element of compact construction results when the reciprocally allocated segments, in the circumferential direction of the air filter element, follow directly.
[0025] Preferably, the sealing line extends in one or more segments with at least almost constant radius of curvature, radially curved away from the filter medium, and / or the sealing line extends in one or more segments with an almost constant radius of curvature towards the filter medium. The curved segments therefore have the shape of a circular segment. For example, this simplifies the programming of the travel path of a dosing robot along curved segments when the seal assembly is produced.
[0026] In an alternative or complementary way, the sealing line may have at least one curved segment that is ellipsoid, parabola or hyperbole in shape. In the same way it can be advantageous when, at least, it is configured in the passage between a straight segment and a curved segment, the change of the radius of curvature depending on a constant function. This preferably applies to the modification of the radius of curvature along at least the entire sealing line.
[0027] An extension of the invention stands out for its space-saving construction, in which the sealing line is radially curved away from a segment of the filter element, extending over a straight segment and along a segment again curved radially in a direction away from the filter medium, with the three segments, in the circumferential direction of the air filter element, following each other directly directly. Thanks to this measure, it results in the scope of the straight segment, a kind of recess, within which, for example, means of fixation on the side of the housing can be integrated.
[0028] According to an exemplified embodiment of the invention, the retainer assembly extends in an axial direction along the filtering medium, covering at least a part of the filtering medium, the part projecting in the axial direction being configured as a spacer with an air filter housing. In this way, the retainer assembly can simultaneously be used as a spacer in order to support the filter element laterally in the air filter housing. This especially stabilizes axially long filter elements within the filter housing. This axial projection can be integrally joined with the retaining assembly or it can also be made up of several parts, that is, sections. Axially elongated sections can be rigid or flexible, that is, elastic. The axial projection may have on one side away from the retaining face, an end that converges towards the filtering medium in order to facilitate the insertion of the filtering element into the air filter housing.
[0029] According to an exemplified embodiment of the invention, the sealing assembly is configured to insert the air filter element into an air filter housing along an axial direction. In this way, the filter housing can be provided with a circumferentially closed body housing with an axial opening, through which the filter element can be inserted axially. The housing body can then be closed with a corresponding cover. Based on the surrounding seal, in an axial seal, a good sealing effect can be expected.
[0030] According to an exemplified embodiment of the invention, the axial recess extends essentially only over one of the outer edges of the retaining device of the filter element. In this way, the filter element can be minimized in one direction with respect to external measures. In particular, the recess does not extend beyond the neighboring outer edge. Because the recess always extends beyond just one edge, the measure of the construction of the filter element can be reduced relative to the edge that does not extend. In the case of several recesses in a filter element, the recesses can extend only beyond two opposite sides of the filter element fitting, but not over the two other opposite sides. In particular, four recesses can be provided, of which two will always be provided on each of two opposite sides, especially near or directly at the axial edges of a filter element.
[0031] According to an exemplified embodiment of the invention, the radial recess extends over the first side face and the second side face in approximately the same measure. In this way, the length required to pass the recess can be reduced. In this way, the necessary protrusion length of the recess can be reduced. Whereas, in the case of a projection on only one side face and a predetermined minimum radius R2, the extent of the projection corresponds at least to the length of radius R2, in the case of a uniform projection on two neighboring side faces, which are at an angle reciprocal of 30 °, with the uniform minimum radius R2, the projection length can be reduced to about 0.3 * R2 without having to reduce the minimum radius R2.
[0032] According to an exemplified embodiment of the invention, the sealing assembly has an elastic sealing material that surrounds the filtering medium, the sealing material extending over the recess. In this way, a sealing material to be applied can be applied easily, simply and quickly along the intended sealing line.
[0033] According to an exemplified embodiment of the invention, a filter medium has four side faces of the filter medium and these side faces of the filter medium and the inflow face and the flow face are preferably projected in a perpendicular converging direction. This results in a simple, parallelepiped filtration medium.
[0034] According to an exemplified embodiment of the invention, an air filter housing is provided which is configured to accommodate a filter element described above. The air filter housing has an inflow opening, a drain opening and a fitting for the filter element, the fitting of the filter element being between the inflow opening and the drain opening. The fitting of the filter element has a hollow radially away from a filter element to be inserted, as well as a circumferential seal assembly, the seal assembly having a surrounding seal line. The sealing line extends into the radial recess, the radius along the path of the sealing line being greater than the radius of an internal edge of the air filter housing in the recess.
[0035] According to an exemplified embodiment of the invention, the fitting of the filter element has a retaining face, this retaining face being between the surrounding seal line and the filtering element to be employed. In this way, outside the seal assembly, it will not be necessary to provide an additional retaining face so that the dimensions of the element and filter can be kept to a small extent.
[0036] Preferably, the retaining face of the filter element housing and a sealing face of the filter element housing, facing in the same direction, are at least widely arranged at the same axial height. Based on this identical measure, no manufacturing tolerances between the two faces need to be taken into account.
[0037] According to an exemplified embodiment of the invention, an air filter housing is provided which is configured to receive a filter element described above, the air filter housing having an inflow opening, a drain opening and a filter element fitting. The filter element fitting is located between the inflow opening and the drain opening, the filter element fitting having a retaining face and a sealing assembly with a sealing line that surrounds the air filter housing. , the retaining face being disposed between the surrounding seal line and the filter element to be used. In this way, the air filter housing can be compact, especially since outside the sealing line it will no longer be necessary to have other elements.
[0038] According to an exemplified embodiment of the invention, an air filter housing is provided which is configured to receive the filter element described above, the air filter housing having an inflow opening, a drain opening and a fitting for the filter element. The fitting for the filter element is located between the inflow opening and the drain opening, the fitting of the filter element having a recess radially distant from a filter element to be used, as well as, it presents a surrounding sealing assembly, the sealing assembly having a surrounding sealing line.
[0039] The sealing line extends in the radial recess, the radius R2 along the path of the sealing line being greater than the radius R1 of an internal edge of the air filter housing that is in the recess. In this way, a compact configuration of an air filter housing can be offered, with a sealing line with a large radius, advantageous for manufacture, compared to a radius of an internal housing edge. In particular, an air filter housing of this type is suitable for correspondingly accommodating a filter element described above with an analogous seal assembly.
[0040] According to an exemplified embodiment of the invention, the air filter housing has a surrounding sealing line, the outline of the sealing line in segments being radially curved and away from a filter element to be inserted. In this way, a sealing geometry can be offered in the filter housing, which can be arranged in the corresponding recesses of the radially curved segments and away from the sealing line, containing a compartment for possible tapering, reinforcement or other elements.
[0041] According to another exemplified embodiment of the invention, the fitting of the filter element has at least one protrusion in the axial direction of the filter element, the protrusion being configured to penetrate a recess on the side of the filter element.
[0042] In this way, a filter housing is offered that corresponds with the filter element described above. In particular, the ridges and recesses can be reciprocally adjusted.
[0043] According to an exemplified embodiment of the invention, the fitting of the filter element has a recess radially away from a filter element to be inserted, the line of the seal extending into the recess and the radius along the path of the line seal is greater than the radius of an inner edge of the air filter housing in the recess.
[0044] In this way, a sealing path with a large radius can be offered in comparison to the internal edge radius of the housing. This allows a simplified application of a sealing compound, that is, the reception of a filtering element that has a sealing compound in this way. The radial recess may, in this case, extend essentially only over one side of the filter housing. Alternatively, the radial recess can also extend past two side faces adjacent to the filter housing, especially in identical size.
[0045] According to an exemplified embodiment of the invention, an air filter is offered with an air filter element described above, and with an air filter housing also described above, the air filter element being arranged in interchangeable shape within the filter element housing of the air filter housing. In this way, the filtering capacity of the air filter can be ensured by interchangeability by replacing the filter element.
[0046] The air filter element and the air filter, as described above and then, are especially used for filtering air in motor vehicles, construction machinery or agricultural machinery. In particular, it serves to filter the air drawn in from a combustion engine or to filter the air fed into an internal vehicle compartment. But they can also be configured in such a way that they are used for other fluids, especially liquids and mixtures of liquids. In particular, they can be configured, largely in the same configuration, but also as a fuel or oil filter element in motor vehicles, that is, fuel and oil filters for motor vehicles.
[0047] The different characteristics can of course also be combined with each other, with which in part advantageous effects can also be obtained that go beyond the sum of the individual effects.
[0048] These and other aspects of the present invention will be explained and demonstrated with reference to the exemplified embodiments described below. Brief Description of the Figures

[0068] Fig. 1 shows an air element 200 according to an exemplified embodiment of the invention. The air filter element 200 has an inflow face 275 and a flow face 285. The inflow face 275, in Fig. 1, can be both on the side facing up, as well as on the non-visible side, facing down . In particular, the filter element 200 can be traversed by the flow in two directions so that the inflow side 275 and the flow side 285 can also be exchanged. The filter element 200 has a longitudinal axis A and can be defined by the direction of the flow through and extending between the inflow face 275 and the flow face 285. It should be understood that the filter element 200 can also be curved, so that the longitudinal axis can be arranged in an inclined direction in the direction of the flow of passage. The longitudinal axis can also be especially curved when the inflow face and the flow face are not positioned in a parallel reciprocal direction and / or when the flow of the filter element 200 occurs not along a straight line, however , along a curve. In addition, the 200 filter element has a central Z axis. This central Z axis marks the central point, that is, a certain symmetrical axis. This can also be differentiated for the inflow face and the flow face. It also does not necessarily have to coincide with the axis of the longitudinal projection A, nor should it be located parallel to this axis. The air filter element 200 has a filter means 210 located between the inflow face 275 and the flow face 285. This filter element can consist, for example, of paper or plastic material or of a fleece or of other random filtering material. The filtering medium can be produced in a different way and manner. For example, the filtering medium can be a folded paper filter bellows or also a "flute" filter medium of wavy and flat layers, glued. The filter element 200 also has a filter element retaining device 240 which serves to secure the filter element 200 within the filter housing 105. The filter element retaining device 240 may, for example, be segmented in one place. external side face of the filter medium. Alternatively, the filter element retaining device can also be a shell, collar or ruler, which surrounds the filtering means 210. The surrounding filter element retaining device 240 will be especially convenient when a surrounding sealing mass is to be provided in the retaining device of the filter element 240. For retaining the filter element 200 in a filter housing, the retaining device of the filter element 240 has a retainer assembly 270, this retainer assembly 270 having retaining faces 271 that are able to accommodate forces corresponding retaining elements acting on the filter element 200. These retaining forces can be advanced on the retaining faces 271 into the filter housing. In addition, the retaining assembly 270 has either one or more recesses 272 which are able to accommodate a corresponding protrusion on the side of the housing so that, for example, they hold the filter element 200 within the housing in the right position. This recess 272 can be found, for example, on the retaining face 271. The recess may also be cylindrical or conical in shape. It can be circular, elliptical, oval or angular in conformation. The retaining set could be configured in the form of recesses that allow positioning on corresponding protrusions within a housing, that is, recesses in a housing. The recesses can essentially extend only on one of the side faces, especially when the recesses are arranged at the corners of the filter element 200, as shown in Fig. 1, they can be configured in such a way that they do not extend beyond the side face here extended of the filter element 200. The recess does not necessarily have to be provided in the corner, but it can also be arranged in the center of a side face of the filter element 200. When a variety of recesses 243 are provided, these may protrude, for example , only on the narrow front sides 211 of the filter element 200, however, not on the wide sides 212. Of course, the recesses can also protrude only on the long sides 212, but not on the short sides 211. This prevents the measure of the construction or the width or length of the filter element 200. The retaining element may, in addition, have spacers 273 which in Fig. 1 extend axially along of the filter means 210. These spacers 273 can ensure a corresponding distance of the filter element 200 within the filter housing 105 with respect to a wall of the filter housing so that the filter element 200, for example, can be easily removed , presenting a defined back and support face in relation to the filter housing. In addition, mechanical stresses such as shocks or vibrations can be more easily accommodated. In this case, the recesses 272 may have different configurations as will be explained below, with respect to Figs. 2 to 4.
[0069] Fig. 2 shows an exemplary embodiment of a retainer assembly, in which, in the retainer device of the filter element 240, a recess 272 in the form of an oblong hole may be provided. This oblong hole-shaped recess is arranged diagonally in Fig. 2 with respect to an external edge of the filter means 210. Alternatively, the recess 272 can also be shaped rounded in the filter element retainer device 240, as can be seen seen in Fig. 3. Alternatively, the oblong hole may also be arranged in parallel with an external edge of the filtering means 210 as shown in Fig. 4. It is understood that alternatively the modalities shown in the recess according to Figs. 2, 3 and 4, the recess can also have other shapes, especially with an angular external contour, that is, a free shape or also an oblong hole with another alignment than the alignment according to Figs. 2 and 4. The recess 272 may, in this case, be a recess that transfixes the retaining assembly 270. Alternatively, the recess 272, however, can also be a closed recess that can be configured, for example, in the form of a hole blind. This recess can then be provided from the upper side of the retainer assembly 270 as shown in Fig. 1. Alternatively, the recess can also be provided below the retainer assembly 270, which, however, would not be visible in Fig. 1 in a blind hole from the perspective. The recess can be shaped conically so that a centering effect is achieved. In the case of forecasting several recesses, a first recess 272 in a first bend 243 can be circular and rounded. A second recess in a second bend may have an oblong orifice in order to achieve a fixation of the filter element 200 through the first recess, still allowing a reduced movement, for example, to compensate for tolerances or thermal expansion, in a direction of oblong hole. The retaining assembly may, in this case, represent an arc, which, as shown in Figs. 1 to 4, has an essentially curved and continuous contour line. In this way, a relatively simple seal can be achieved, as will be explained below.
[0070] Especially in the filter elements with small edge radii, a special difficulty may be that the filter element is reliably sealed inside an air filter housing in order to separate the fresh air side from the raw air. For a sealing arrangement, it is therefore advantageous in certain circumstances when they have an enlarged radius. This is especially important also for the manufacturing process, in which less radius change ', that is, less curvature, facilitates a process for dosing the sealing material. It is generally easier in a manufacturing process to cover a larger radius than a sharp-edged pass through an edge. This will be explained in more detail with reference to Figs. 5 and 6.
[0071] Fig. 5 is a detailed view of a retainer assembly 270 which is shown in the form of an arch 243. This arch extends from the filter medium 210 only over a side face 211 of the filter medium 210. The retainer assembly 270, in Fig. 5, however, does not extend beyond the side face 212. The contour can, for example, extend in a straight line along the side edge 212, then it can follow a radius R2 in about 135 ° counterclockwise, then follow the radius R2 by about 45 ° clockwise, then follow the section along the side face again 211. In this case, the arching does not protrude beyond the side face 212.
[0072] In the last geometry (Fig. 21), the arching extends beyond the side face 211 as well as the side face 212 and essentially to the same extent. In the two cases mentioned above, the radius is not less than R1. The radii of curvature traversed by the sealing line 261 in the area of the edges, thanks to the arching 243 are greater than in the case where the sealing line 261 extends in the area of the corners in the immediate proximity of the filter medium 210.
[0073] To apply a sealing compound in the arrangement shown in Fig. 5, an automatic dosing unit can move directly around the contour of the filter element 200, however, when an end of the side face 212 is reached, it will be it is necessary to move through a small radius R1 and then apply a sealing compound on the side face 211. This sharp change of direction results in inaccuracies in the dosage and implies the danger of an overdose or underdosing of the sealing compound. The bending 243, however, makes it possible for an automatic dosing unit to move in a larger radius R2 which has a smaller gradient than the sharp edge radius R1. In Fig. 5, the automatic dosing unit can now follow on the edge edge 212 of the contour of the retainer assembly 270, so that in this way it is only necessary to move in curves with a larger radius R2 and then end of retainer assembly 270 reaching side face 211. Fig. 5 shows a retainer assembly 270, that is, a filter element retainer device 240, which is mounted only on a partial segment of the filter medium 210. With a geometry of this type of retainer assembly, the sealing mass, when desired, may be injected out of the partial segment directly into the filter medium 210, on the side face 212 until its end, to then follow the recess and then the side face 211. The filter element retaining device 240 may, however, also have a surrounding collar, on which the sealing compound can then be placed. The filter element retaining device 240 may, in this case, also be adhered in a dense manner with the filter means 210.
[0074] Fig. 6 shows an exemplified embodiment of the invention, in which a sealing compound 263 is applied to a filter element retaining assembly 240. In this case, the filter element retaining assembly may exceed filter medium 210 , representing a type of collar on which the sealing compound 263 can be applied. The presentation of Fig. 6 can also be considered as a presentation of a set surrounding the filter element retainer 240, on which a further application must be made. sealing compound, the line of dashes and dots in both cases representing a sealing line 261. The support face of the filter element retaining assembly 240 represents a sealing face on which an elastic sealing material can be applied 263. Also in Fig. 6, it can be recognized that the radius of the sealing compound R2 is essentially greater than the radius R1 of the filter medium 210 so that a corresponding automatic dosing unit can move over the sealing line 261 with a speed essentially greater than a sharp edge 213 of the filter element 210. In this case, the recess 243, in the form shown in Fig. 6, projects essentially only on the side face 211 of the filtering means 210, where it is emphasized, however, essentially, does not extend beyond the side face 212. The arching 243 extends, in this case, in an angular sector that is formed by the outer edge 241 of the retaining device of the filter element 240 , edge is continued in the direction of edge 213, in Fig. 6 characterized with a dashed line 241a and with extension of the second outer edge 242, marked in Fig. 6 with a dashed line 242a. In this way, the entire width between the outer edge 242 of the filter element retaining device and the opposite side of the filter element retaining device (not shown) can be kept to a small extent, with the result that the entire measurement of the mounting of the filter element filtering element is now reduced. The bending 243 therefore has the function that the radius of a sealing compound R2 can be maintained in a large form to enable a fast manufacturing process. In addition, the arching 243 has, however, yet another additional function that it offers a suitable point for a recess 272. As this face 271 is arranged in any way, it will no longer be necessary to offer another additional face in order to ensure, in addition of the seal with a large radius a retaining face, that is, a recess. In this way, the ear-shaped arching 243 has the combined function of offering both a retaining face 271, that is, a face for the recess 272, as well as a face optimized for a seal assembly 260. The recess 272 can in this case be configured as a blind hole. This will have the effect that the recess does not provide a passage for air to air between the fresh air and raw air side, especially when the recess is between the sealing line 261 and the filter medium 210.
[0075] With reference to Fig. 7, the top view of a filter element 200 according to the invention is now shown. The filtering element 200 shown in Fig. 7 shows in its four corners, in its four corners, archings 243. These archings 243 also serve here, in a similar way, with the geometry of Fig. 6, both to accommodate a set seals 260 with extended radius R2, as well as to offer a retaining face 271. In this way, if necessary, a recess 272 can also be provided on the retaining face 271, that is, a recess in the retaining assembly 270. Like the bends 243 do not extend beyond the outer edge 242, that is, its extension 242a of the filter element retaining device 240, the entire width of the filter element may be kept to a small extent. In particular, the archings 243 extend only at an angle that is formed between the outer edge 241 and its straight extension on the one hand and the extension 242a of the outer edge 242 on the other side.
[0076] Next, the route of the sealing line 261 based on Fig. 7 will be explained in detail. Starting from the left side center in Fig. 7 of the air filter element 200, the sealing line 261 runs in a circumferential direction of the air filter element 200 in a clockwise direction, initially, in a straight segment of the side face of the filter medium 212. Approximately at the height of the edge between the side faces of filter medium 212 and 211, the straight segment converges directly in the direction of a radially curved segment in the direction of filter medium 210 (in Fig. 7, curved to the right side, that is, curved clockwise). In this segment, the sealing line 261 has at least almost a constant radius of curvature, for example, in the area of about 20 to 40 mm, preferably in the area of 25 to 35 mm. It is, therefore, a segment in the shape of a circular segment. The sealing line 210 follows the segment in a circular shape at about 135 °. Now, immediately follows, a segment curved in the direction of radial distance from the filter medium 210 (in Fig. 7, curved to the left side, that is, curved counterclockwise), whose radius of curvature is preference is also almost constant, being of approximately the same length, preferably slightly smaller, than the radius of curvature of the preceding segment. this segment of travel distance curvature extends about 45 °. Next, there is a straight segment along the lateral face of the filtering means 211, which in another segment curved away, which essentially has the same radius of curvature (for example, 20 to 40 mm) and the same measurement angle, for example, about 135 °) as the first cured segment and in the mentioned distance. Finally, a curved segment follows in the direction of the filtering means 210, which essentially has the same radius of curvature and the same angle measurement as the first curved and approaching segment. At the height of the edge between the lateral face of the filter medium 211 and the other lateral face of the filter medium 212, the curved segment in the direction of approach becomes a straight, elongated segment along the lateral phase of the filter medium 212 Now, they follow, again, curved segments in the direction of approach and in the direction of distance etc.
[0077] Altogether, in order to always conform to an arching 242, a curved segment in the direction of approach and a curved segment in the direction of removal of the filter medium 210 are positioned in each of the four corners of the air filter element. In the example shown in Fig. 7, all segments curved in the direction of spacing have the same radius of curvature and the same angle measurement. Also, all the segments curved in the direction of the filter means 210 have the same radius of curvature and the same angular measure.
[0078] As indicated in Fig. 7, in the retaining faces 271 a recess 272 may be provided. This recess is shown in Fig. 7 as an oblong hole. Analogous to the modalities in Figs. 2 to 4, this oblong hole, however, can also have another alignment. Alternatively, the recess can also have any other random format. In particular, the recess can be shaped like a through hole. However, recess 272 can also be configured as a blind hole, that is, a closed recess. This recess allows, for example, to accommodate a projection on the side of the housing in order to correctly position the air filter element 200 within an air filter housing. In particular, in the case of air filter elements that apparently do not have a preferred mounting orientation, a corresponding protrusion on the housing side, that is, a recess in the air filter element, can ensure that the air filter element is inserted in a correct orientation inside the air filter housing. The sealing face 262, that is, the sealing line 261, after traveling along the oblong sides 212 of the filter element 200 and after revolving over the arch 243, can be guided again along the narrow side 211 of the element filtering 200. In this way, the filtering element 200 may have a smaller mounting dimension between the corresponding archings 243 so that, for example, sets 113 on the housing side, such as shoring or screwing, may be arranged in this region if it is necessary to offer space that exceeds the filter element 200, that is, its bends 243. For this purpose, the bending radius, after passing a 90 ° circular segment, can pass, for example , another 45 ° circular segment along the same curvature to later cross a curvature opposite to a 45 ° circular segment and, then, to receive an alignment again nt that extends in parallel to the outer edge 211. The radius R2 can, in this case, essentially be maintained, changing only the curvature when passing through the circumference in phases from one curvature to the right, to a curvature to the left , that is, vice versa.
[0079] Fig. 8 shows an exemplary embodiment of an air filter housing to be used in an air filter element according to the invention. The air filter housing 105 shown in Fig. 8, referring to an air filter 100, has a housing body 110 and a housing cover 115. The housing cover 115 is - in the embodiment shown in Fig 8 - an air inlet 130, that is, an air outlet 140. This opening shown in Fig. 8 can, in this case, be used both as an air inlet, and also, alternatively, as an air outlet. In the same way, an opening is provided in the body of the housing 110 which cannot be seen completely here and which can also be used as an air inlet 130 as well as an air outlet 140. The cover of the housing 115 presents, in the modality shown here , an arrangement of reinforcement ribs. The housing body 110 has a collar 114. This collar has a corresponding contour in the direction of the outer contour of the air filter element 200. In this way, for example, the retainer device of the filter element 240 with the contour with its four arches 243 (see Fig. 7) inside the collar 114. The sealing compound 263 can, in this case, be applied both on the upper side of the filter element retaining device and on the lower side. Correspondingly, there is the corresponding sealing counterface 102 of the set of seals 160 on the housing side, in the housing, or in the housing body 110 or in the housing cover 115. The sealing line 161 is formed as a surrounding sealing line. Conditioned by the bends 143, the sealing line 161 extends in the housing not with an exclusively positive curvature, that is, seen from the outside, convex, however, besides the straight segments, they also have concave segments and, especially, on the narrow sides. For example, in the grooves of the concave sealing line 161, a corresponding screw fastening 113 can be installed, saving space. The housing can have corresponding projections 172 which can project into the corresponding recesses 272 of the filter element 200. In the housing there is a socket for filter element 170 that can receive a corresponding retainer assembly 270 of the filter element 200. The projections 172 can be provided in this filter element socket 170. By the corresponding configuration of the recesses 272 as oblong holes, a certain tolerance in positioning can be achieved. By a corresponding conformation of the protrusions 172 in the housing, that is, of the recesses 272, it can also be ensured that the filter element 200 can be inserted into the housing only in a predetermined position. As can be seen in Fig. 8, in the corresponding areas that have become free, located between the archings 243 of the filtering element 200 and the archings 143 of the housing, 113 corresponding sets can be provided on the housing side, such as, for example, taper. In this way, the overall dimension of the housing will not be increased although the sets 113 on the housing side go beyond the corresponding shape of the housing. In addition, the retaining faces 271 can rest on corresponding support faces 171 in the housing, so that correct axial positioning of the filter element 200 can be achieved. By means of correspondingly configured rest faces, moreover, it can be achieved that the sealing mass 263 is compressed to a certain maximum extent, so as not to be crushed by the screw in the housing cover.
[0080] Fig. 9 shows an arrangement, in which the filter element 200 is inserted into the air filter housing 105 so that, together with the air filter housing 105, they formed air filter 100. Fig 9 alternatively shows that instead of corresponding recesses 272, corresponding protrusions 272a can also be provided which can penetrate corresponding recesses 172a in the housing. Thus, for example, by a combination of corresponding protrusions and recesses in a filter element 200 and corresponding protrusions and recesses can be ensured in the air filter housing that only filter elements 200 suitable for the air filter housing can be inserted . The projections and recesses can be configured in such a way that an air filter element 200 that does not fit correctly protrudes in such a way beyond the sealing geometry of the air filter housing that the cover 115 of the air filter housing does not more can be closed. The side faces 211, that is, 212 can, in addition, have a reinforcement as can be seen by the ribbed structure in Fig. 9 in the filter element 200. In particular, the arching 243 of the filter retainer device 240 may be arranged on the side of the filter element 200 which is reinforced by a corresponding reinforcement structure. In this way, especially on the already reinforced side 211 of the filter element 200, the corresponding holding force can be applied on the filter element 200, that is, the filter medium 210. In this case, the seal can be applied both in one collar of the filter element retaining device 240, however, also on an external edge of the filter element retaining device 240. In particular, an edge of the filter element retaining device may be bathed in such a way with a sealing compound, especially a elastic sealing compound, that this sealing compound surrounds the edge as a protection against shock. The sealing compound can be applied along the longitudinal sides 212 of the filter element 210 and also directly on the filter medium. There, other retaining geometries are necessary, however, not necessarily, for the reception of the sealing mass. The sealing compound can have different cross sections. Especially the cross section of the sealing compound can be rectangular, semicircular, trapezoidal or in semi-elliptical or semi-oval shape. However, the cross-sectional shape of the sealing compound is not restricted to the cross-sectional shapes mentioned.
[0081] Fig. 10 shows a reinforced structure in the form of a terminal disk 300 of another example of an element 200 of an air filter 100. The air filter 100 is largely identical with the air filter 100 described based on Figs. 7 to 9. Same or identical components have the same reference number.
[0082] On the two side faces of the filtering means 211 of the filtering element 200, a terminal disc 300 shown in Fig. 10 is attached, for example, by gluing or soldering the terminal discs 300 with the filtering means 210. In the two other faces of the filtering means 212 are not provided with a reinforcement structure. In the case of a filter medium 210 folded in a zigzag pattern, the terminal discs 300 also serve for lateral sealing of the fold pockets. The individual terminal disc 300 is preferably produced from plastic (hard) material, especially as an injected part.
[0083] As part of the retainer device of the filter element 240, in the end disc 300 there is provided a retainer set 270 with two arches 243. The end disc 300 according to Fig. 10 still lacks the seal assembly 260. To configure the seal assembly 260, the sealing compound 263 will be so shaped in the terminal disc 300 that the sealing compound 263 involves a fixing thread 301. The fixing thread 301 is joined over a variety of retaining threads 302 with the outer face of the end disk 300. This mesh results in a particularly firm connection of the sealant 263 to the end disk 300. Especially, the sealant 263 will be injected, that is, foamed into the terminal disk 300. Preferably, a PUR element serves as sealant 263. Especially the disk terminal 300 has a hard plastic and as sealant 263 it has a soft plastic. However, it is also conceivable that the entire terminal disc 300 is injected or foamed with or without sealing compound 263, covering the material, for example, of PUR.
[0084] Figs. 11 to 13 show by cutout, the air filter element 200 with the terminal disc 300 of Fig. 10, whereas in Figs. 11 to 13, the sealing compound 263 is already molded. The sealing compound 203 forms a sealing assembly 260 that has a sealing face 303 (Fig. 11) that extends circumferentially and perpendicularly to the longitudinal axis Z of the filter element 200. In the bends 243 a retaining face 271 is provided arched in an upward direction in Fig. 11. The retaining faces 271 are axially offset in relation to the sealing face 303. In the foaming of the sealing material 263 it will be avoided with this axial lag that based on an accidentally reduced overdose of the sealing mass 263, this can reach the retaining face 271.
[0085] On the opposite side of the seal set 260, a second sealing face 304 is provided, that is, round sealant (Fig. 12), circumferential. In the bends 243 a retaining face 271 is provided in Fig. 12 facing downwards. These retaining faces 271 are axially recessed to a small extent in front of the sealing face 304. A direct view to one of these retaining faces 271 is shown in Fig. 13. In addition to a recess 272 for receiving a projection on the housing side, it also has other recesses which only serve to save plastic material.
[0086] Fig. 14 is a sectional view of the filter element 100, integrated in the filter housing 100, in the region of the center of the terminal disk 300. On the sealing face 303 on the side of the element, it will be pressed an axial sealing face 305 on the housing side which is configured in a sealing thread surrounding the housing cover 115. On the sealing face 304 on the element side, in the opposite axial direction, a sealing face 306 is pressed on the housing side which is configured in a step surrounding the housing body 110. It is an axial sealing geometry. In Fig. 14, the sealing compound 263 is shown in an unpressed state, that is, not deformed. Effectively, the sealing mass 263 does not overlap together with the components on the housing side, however, it is deformed in such a way that it touches these components in a dense manner. Aside from this, Fig. 15 shows how the sealing compound 263 surrounds the fixing thread 301.
[0087] The housing cover 115 and the housing body 110 have retaining faces 171 on the housing side (not shown in Fig. 14), which in the assembled state of the filter element 200 abut the retaining faces 271 on the housing side element (on the upper side and the lower side of the bends 243). This results in a firm retention of the filter element in the filter housing 100 on the bends 243, at least in both axial directions. Preferably, the sealing face 306 on the housing side and the retaining faces 171 facing in the same direction (in an upward direction) on the housing side and belonging to the housing bodies 110 extend at the same axial height. Failures in technical tolerances of production of the relative axial position of these faces are avoided.
[0088] Fig. 15 shows in section corresponding to Fig. 14, another example of an air filter 100, that is, an air filter element 200, with a slightly modified sealing geometry. In addition, the filter of 100 corresponds to the examples described above. The sealing compound 263 surrounding the fixing thread 301 has a modified shape. It has a groove surrounding 307. After assembly, in this groove 307, a sealing thread 308 fits on the side of the housing. The groove 307 and the sealing thread 308 are dimensioned in such a way that the outer face of the wall of the outer groove 309 is pressed radially outwards against an inner wall of the housing. A radial seal results. In addition, the sealant 263 may also touch axially on the opposite side of the groove 307, on one face of the housing in order to stabilize the seal or even to produce an additional axial seal.
[0089] Another example of an air filter element 100 can be seen in Fig. 16 in a top view. The filter element 200 can be broadly configured identical with the filter elements 200 described above. It has two terminal discs 300 which are joined with the side faces of the filter medium 211. It is shown, for example, that the sealing line 261, always in the passage of a side face of the filter medium 212 to the face of the narrow outer edge of the terminal disc 300, passes through a bend in S 310. In order to guarantee a safe working connection of the filter medium 210 in the terminal discs 300, these need laterally stand out to a lesser extent in relation to the filter medium 210. Thanks to the S-bends 310, the filter element 200, notwithstanding the side discs 300 laterally protruding, with the same volume available for the filter medium, can also be constructed in a slightly smaller form.
[0090] Another example of an air filter 100 will be described based on Figs. 17 to 20. Fig. 17 shows the air filter ready for service. The filter housing 105 has a removable housing cover 115 and a housing body 110. The housing cover has a lateral flow opening 130, that is, an inflow opening 140. The housing body 110 has correspondingly a inflow opening 140, that is, a flow opening 130 (Fig. 19).
[0091] Fig. 18 is a sectional view, in sections, along the dashed line 311 indicated in Fig. 17. The sealing compound 263 is profiled on a border 312 surrounding the filter element 200. The sealing faces surrounding 303 and 304 of the sealing compound 263 are sealingly abutted on the sealing faces 305 and 306 surrounding and on the housing side. The edge 312 forms the archings 243. The retaining faces 271 facing downwards in Fig. 18, next to the archings 243, touch the corresponding retaining faces 171 of the housing body 110. The retaining faces 271 in Fig. 18, facing upwards , have a reduced distance to the corresponding retaining face 171 on the housing side. But they can also be configured in such a way that they also touch. Through a hollow projection 313, a recess 272 is formed on the underside of the arch 243, into which a projection 172a penetrates on the side of the housing. For material savings, this protrusion 172a is also hollow.
[0092] Fig. 20 shows the filter element 200 with the circumferential edge 312 which is provided with the circumferential seal assembly 260, the archings 243 and the hollow projections 313. For example, the filter element 200 also has a variant of a filter 200 showing a surrounding frame 324. Part of frame 314 is the surrounding border 312. But it also serves for lateral sealing and stabilization of the filter element 210. Preferably, the circumferential frame is injected from plastic or is injected into the filter medium 210 through an injection molding process. It is therefore a filter element 200 bathed in plastic. The sealing line 261 of the sealing assembly 260 extends correspondingly to the sealing line 261 of the filter element 200 described based on Fig. 7.
[0093] Two examples for filter elements 200 with a modified path of the sealing line 261 are shown in Fig. 21 and 22. The shown filter elements 200 are also plastic-coated filter elements 200. A corresponding sealing path can, however. Also, be realized in the filter elements 200 with two opposite terminal discs 300 or other filter elements 200 of other constitution.
[0094] In Fig. 21, the bends 243 - contrary to the elements 200 described above - are not just in front of a side face of the filter medium 211, 212 are arranged in front of the two side faces of the filter medium 211, 212, especially by the same measure. In the extension of the arching 243, the sealing line 261 is projected at the beginning along a curved segment in the radial direction of the filtering means 210, then passing along a radial curvature segment and finally passing again along a segment radial curvature in the direction of distance.
[0095] Fig. 22 presents an example of a filter element 200 that initially, at least based on the formation of the arches 243, is not of specular symmetry. Thanks to this measure, the filter element 200 can only be mounted inside the filter housing 105 according to a single predetermined position. In general, an unequivocal mounting position of a filter element 200 can be defined by profiling (for example, radius of curvature, radial projection, etc.) and / or by the number and / or position of the bends 243.
[0096] In general, too, it may be advantageous to produce the bends 243, that is, the entire retaining assembly 260, that is, the entire retaining device of the filter element 240, of a polymeric foam, especially a foam of PUR.
[0097] It should be noted that the present invention, in addition to air filters, can also be used with liquid filters.
[0098] It should be noted that the expression "encompassing" does not exclude other elements or procedural steps, in the same way as the expression "one" and "one", several elements and steps are also not excluded.
[0099] The reference numbers used serve only to increase understanding and should in no way be considered as restrictive, being that the protection area of the invention is reproduced in the claims.
