    Invention Patent Descriptive Report for FILTER DEVICE, PARTICULARLY AN OIL OR FUEL FILTER.
    [001] The present invention relates to a filter device, particularly an oil or fuel filter, with a filter housing, which features a filter housing container and a filter housing cover.
    [002] In filter devices according to the species, to guarantee the use of an authorized annular filter element, a pin is often arranged on it, which protrudes axially from a lower terminal disc, and through which the annular filter element with the assembled filter device is inserted into a channel on the container side of the filter housing and the filter device can be started up only when the annular filter element has the necessary pin in the correct location. In this way, the use of unauthorized annular filter elements can be avoided, in particular, and damage can be prevented, for example, in an internal combustion engine. However, it has often proved difficult to assemble these types of filters, particularly the assembly of the annular filter element in the filter housing. [003] The present invention therefore relates to the problem of indicating for an filter device of the type according to the species, an improved modality, or at least alternative, that, on the one hand, is formed in a constructively simple way and, on the other hand, it facilitates assembly of the filter device.
    [004] This problem is solved according to the invention. Advantageous modalities are the object of the embodiments.
    [005] The present invention is based on the general idea of providing in a filter device itself known, with a filter housing that features a filter housing container and a housing cover
    Petition 870190004062, of 14/01/2019, p. 4/21
    2/12 filter, a tubular rod in the filter housing container, which serves as a guide for an annular filter element, to be inserted into the filter housing container. The annular filter element to be used has an axially protruding pin on a lower end disk, whereby the annular filter element with the assembled filter device is inserted, at least partially, into a channel on the container side of the filter housing and closes it tightly. The tubular rod, provided according to the invention, of the filter housing container, with a mounted filter device, is inserted into an internal space of the annular filter element. At its free end, this tubular rod according to the invention has a guide contour, which interacts with a guide element arranged in the filter element, such that in the assembly it is guided along the guide contour and, with this, it allows a simple and exact insertion of the pin in the channel on the container side of the filter housing. The provision of the guide contour on the tubular rod of the filter housing container offers, in this case, not only an extremely simple constructive possibility for guiding the annular filter element, but in this way, other guide contours can also be dispensed with particularly, often configured in a complex way. Despite the relatively simple constructive modality of the guide contour, it produces, in the assembly of the filter device, an exact and objective-oriented guide of the annular filter element, with a sliding pin on the side of the filter element annular along the guide contour, it can be safely guided in the direction of the channel on the container side of the filter housing and can also be inserted into it. With the tubular rod provided for in accordance with the invention, with its guide contour, the installation of the filter device can also be significantly simplified.
    Petition 870190004062, of 14/01/2019, p. 5/21
    3/12 [006] In an advantageous improvement of the solution according to the invention, the guide contour on the rod side has an axial groove, for which the guide element is guided in the assembly of the filter device and which is arranged such that in relation to the pin on the side of the annular filter element, it is inserted into the channel on the container side of the filter housing, as soon as the guide element enters the axial groove. This precise alignment of the pin with respect to the guide element and the interaction of the guide element with the guide contour on the rod side means that only annular filter elements can be inserted into the filter device, but not other annular filter elements. , which, for example, do not have a pin. In them, the channel on the container side of the filter housing is not closed and allows a bypass current, which bypasses the annular filter element, which greatly reduces the filtering effect of the filter device. When using annular pin filter elements, both the guide element and a distance between it and the pin must correspond to previously defined measures exactly, so that, in an interaction of the guide element with the guide contour on the side of the stem, the pin also enters the channel on the container side of the filter housing, when the guide element is inserted into the axial groove of the guide contour. In general, therefore, the use of unauthorized annular filter elements is at least severely hampered, whereby damage to an internal combustion engine connected with the filter device can be reduced or excluded altogether.
    [007] In an advantageous improvement of the solution according to the invention, the guide contour on the rod is formed in the manner of a circular ramp, the axial groove being arranged between the highest and the lowest point of the ramp. In a placement of the annular filter element, it therefore slides with its elePetição 870190004062, from 01/14/2019, p. 6/21
    4/12 guide length along the circular ramp, until it reaches the axial groove and can be inserted into it, or slide into it.
    [008] This insertion or sliding process can, in this case, be produced, for example, by means of a screwing process of the filter housing cover over the filter housing container. Alternatively, it is also conceivable that the guide contour on the stem is formed in the manner of a chamfered cannula, the deepest point being arranged in the axial groove. In that case, particularly easy conduction of the guide element to the axial groove can be obtained, and thus particularly easy conduction of the pin to the channel on the container side of the filter housing. Unlike filter devices known in the art, in which the pin on the side of the annular filtration element was often used as a sliding element, the pin according to the invention no longer needs to have such a sliding property and, for this reason it can also be formed, for example, of an elastic material, approximately rubber. The tubular rod in the filter housing container can in this case be a part of a purified channel.
    [009] Other important features and advantages of the invention are evident from the embodiments, the drawings and the respective description of the figures by means of the drawings.
    [0010] It is understood that the characteristics mentioned above and yet to be explained below can be used, not only in the combination in each case indicated, but also in other combinations or alone, without leaving the scope of the present invention.

    [0033] According to figure 1, a filter device 1 according to the invention, for example, an oil or fuel filter, or an air filter for a car, has a filter housing 4 formed by a container of filter housing 2 and a filter housing cover 3, which can be screwed with it. In this case, an annular filter element 5 in itself is arranged within the filter housing 4, which is supported in relation to an internal space 6, for example, by means of an internal frame 7 in the manner of a supporting structure. The annular filter element 5 is limited in an axial direction, in this case, also in a known manner, by an upper terminal disk 8 and a lower terminal disk 9. In the axial direction, protruding from the lower terminal disk 9, it is provided in that case, a pin 10 (comp., for example, figures 6 and 7), which on filPetition device 870190004062, from 01/14/2019, p. 9/21
    7/12 tro 1 completely assembled, it is inserted, preferably hermetically, into a channel 11 on the container side of the filter housing and thus closes it. For that purpose, a sealing element formed in a known manner, for example, an O-ring seal 12, can be provided on pin 10. Channel 11, in this case, in most cases, is a discharge channel.
    [0034] In addition to the filter housing container 2, a tubular rod 13 (shown in figures 2 and 3), which with the filter device 1 fitted, is inserted into the internal space 6 of the annular filter element 5 and forms, for example, a part of a purified channel. According to the invention, a guide contour 14 is then provided at a free end of that tubular rod 13, which interacts with the guide element 15 disposed in the annular filter element 5 (comp., For example, figures 4 and 5). This guide contour 14 can be formed, for example, in the form of a circular ramp, as shown in figure 3, or else in the form of a chamfered cannula, which is represented, for example, according to figure 2 In this case, the two guide contours 14 have in common the fact that they have an axial groove 16, to which the guide element 15 is guided in the assembly of the filter device 1 and which is aligned in such a way that In relation to the pin 10, it can be inserted in the channel 11 on the container side of the filter housing, as soon as the guide element 15 enters or is inserted in the axial groove 16.
    [0035] An assembly of the filter device 1 is represented in several process steps according to figures 4a to 4d. First, in the assembly step 4a, the annular filter element 5 is inserted into the filter housing container, more precisely, to the point where it rests with the guide element 15 on the guide contour 14 on the side of the stem. Subsequently, the element
    Petition 870190004062, of 14/01/2019, p. 10/21
    8/12 of annular filter 5 is twisted, for example, by screwing the filter housing cover 3, so that the guide element 15, as shown in Figure 4b, slides along the guide contour 14, and, more precisely, to the axial groove 16, which is preferably arranged between the highest point and the lowest point of the guide contour 14 formed in the manner of a ramp. After reaching the axial groove 16, the pin is oriented axially in line with the channel 11, so that the annular filter element 5 can be inserted in axial direction with the guide element 15 in the axial groove 16 and at the same time , with the pin on channel 11. This state is shown, for example, according to figure 4d.
    [0036] In the same way, a process for assembling the annular filter element 5 works in a formation of the guide contour 14 in the manner of a cannula, as shown in figures 5a to 5d. In such a guide contour 14, the axial groove 16 is preferably located at the deepest point of the guide contour 14. In this case, it is irrelevant whether the guide element 15, as shown, for example in accordance with figures 4a to 4d, it is arranged in the inner frame 7, or, as shown in figures 5a to 5d, in the lower terminal disc 9. In both cases, in this case, the guide element 15 is formed as a guide pin directed radially inward.
    [0037] Examining figures 4a to 4d, it can be seen that the lower terminal disc 9 is sealed in relation to the stem 13 through a sealing lip 17, which on the annular filter element 5 is hermetically abutted in a outer surface of the tubular rod 13. This sealing lip 17, in this case, is flexible and preferably formed in one piece with the lower terminal disc 9. For the sealing function it is irrelevant, in this case, if the sealing lip points upwards on the mounted annular filter element 5, as shown, by
    Petition 870190004062, of 14/01/2019, p. 11/21
    9/12 example, according to figure 9, or downwards, as shown, for example according to figure 10. Alternatively, it is also conceivable that a separate seal ring 18 is provided on the lower end disk 9 , which, on the annular filter element 5, leans against the outer surface of the tubular rod 13. Such a sealing ring 18 is shown, for example, in figures 5, 7, 11, 14, 15a and 16c.
    [0038] It is of special advantage in the filter device 1 according to the invention, that not as yet, of the state of the art, the pin 10 slides along the ramp and, thus, is formed as a sliding element, but that it can be formed, for example, from rubber, since pin 10 no longer needs to have any sliding properties.
    [0039] Looking at figure 6, then it can be seen that, unlike figures 7 and 8, pin 10 can be formed simply in a tubular shape and support an O-ring seal on a head. On the other hand, of course, the pin 10 can also have a cross-sectional structure in the form of a cross, as is visible, for example, according to figures 7 and 8, with which the pin 10 becomes more rigid, in the total. The annular filter element 5 can be formed as a fold star with a paper or fluid filter material.
    [0040] According to figure 9, an annular filter element or, in detail, the lower terminal disk 9 of the same is shown, which also has a tubular pin 10 only tubular, on whose free end there is still a sealing of O-ring 12. Unlike figure 10, in this case, the lower terminal disc 9 of the annular filter element 5 has a sealing lip 17 pointing upwards according to figure 9. In this case, in general, it is conceivable that the complete lower terminal disk 9 is produced, pre-injected, from a single
    Petition 870190004062, of 14/01/2019, p. 12/21
    10/12 material, for example, plastic or rubber, so that the sealing lip 17 is only molded on the lower terminal disc 9.
    [0041] According to figures 11a and 11b, different seals 18, 19 are shown, the seal according to figure 1la, similar to that according to figure 15b, being formed, for example, only as sealing liner 19 on an annular rib 20 pointed inwardly. On the other hand, the sealing ring 18, as shown according to figures 11b, 14 and 15a, is formed as a separate component, for example, of silicone or a non-woven material.
    [0042] According to figure 12, an explosion representation is shown, as well as an assembly position of the inner frame 7, with the respective lower terminal disk 9, the same, in the case of figure 13a, may show a sealing lip 17 directed upwards and, in the case of figure 13b, a sealing lip 17 directed downwards. The guide element 15, in this case, is disposed on the inner frame 7, which, at the same time, has another guide element 15 ', which interacts with a guide contour 14' disposed on the lower terminal disk 9. On the other hand , the guide element 15 according to figures 14 and 15 is disposed on the lower terminal disk 9. Unlike figure 13a, b, the lower terminal disk 9 according to figure 15 does not have a sealing lip 17, but on the contrary, a sealing ring 19 (shown in figure 15a) or a sealing lining 19 (shown in figure 15b).
    [0043] According to figures 16a, b and c, the individual sealing variants are shown again, so in accordance with figure 16a, a sealing lip 17 is shown pointing upwards and leaning against the stem 13, while the lower terminal disc 9 according to fig. 16b has a sealing lip directed downwards. According to figure 16c, another variant of the
    Petition 870190004062, of 14/01/2019, p. 13/21
    11/12 guide contour 14, in which case an additional sealing ring 18 is arranged on the lower terminal disc 9. According to figures 17a and 17b, it is shown once again how the sealing lip 17, in the embodiment according to figure 16a, abuts the external side surface of the stem 13, once the annular filter element 5 has reached its final angular position of rotation and can be moved axially downwards. A condition for such axial displacement of the annular filter element 5 through the stem 13 is that the guide element 15 on the side of the annular filter element is located in the axial groove 16, which at the same time means that the pin 10 can be arranged coaxially aligned with channel 11 on the container side of the filter housing and can be inserted into it. This is represented, for example, according to figures 17a and 17b. [0044] In figure 18 another filter device 1 is shown, with a check valve 21, as well as a bypass valve 22. Also in this case, the stem 13, which, in turn, is also centrally arranged, presents a guide contour 14 at its free end, which interacts with a guide element 15 on the side of the filter element, not shown. Here again, a pin 10 not shown is arranged on the annular filter element 5 or on the lower terminal disc 9 of the same, which is inserted into the filter device 1 completely assembled in a channel 11 on the side of the filter housing container (comp. figure 19) and, with that, closes it tightly.
    [0045] With the filter device 1 according to the invention, decisive advantages can be obtained with regard to its operation and assembly: on the one hand, an unauthorized use of an annular filter element, which, for example, would also lead to damage to an internal combustion engine, can be safely prevented, since they would need to present both the element
    Petition 870190004062, of 14/01/2019, p. 14/21
    12/12 of guide 15 on the side of the annular filter element, as well as the guide contour 14 on the side of the stem, as well as the pin 10 exactly aligned with the guide element 15, so that it can be correctly mounted on the filter device 1. If, for example, an annular filter element without a pin 10 is used, then channel 11, particularly the discharge channel, is not closed hermetically and a bypass current occurs, which bypasses the annular filter element. At the same time, the assembly and, in particular, the replacement of the annular filter element 5 can be clearly simplified, since by means of the guide element 15 and the guide contour 14 a forced conduction is given, which positions the annular filter 5 in the screwing of the cover of the filter housing 3, necessarily, in such a way that the pin 10 can be oriented in line with the channel 11 and, thus, be inserted, without problems, in it. Another advantage is that in the present filter device 1, the pin 10 no longer needs to have sliding properties and, for that reason, it can be formed, for example, in a markedly more flexible way, particularly rubber.
