    State of the Art
    [0001] The present invention relates to the attachment of fuel injectors for high pressure feed injection systems, such as the "common-rail" injection system in injector test benches, several possibilities are available for the attachment of the fuel injectors to be tested to the injector test benches, which are dependent on the fuel injector seal with respect to a positionable injection chamber on the test bench. There is the possibility to seal the fuel injectors housed in the injector test bench in radial direction in the injection chamber or to produce a seal in axial direction.
    [0002] With radial seal in the region of the fuel injector nozzle, as a rule, it is enough to fix the fuel injector inside the injector test bench in the upper region, because in this case there is no axial force. Fastening the fuel injector in the upper region occurs, for example, by simply tightening the fuel injector on a test pressure conductor, which activates with system pressure the test piece subjected to the injector test bench. Other designs provide for a tightening of the fuel injector to its injector body by means of a slotted round bushing or clamping jaws similar to screw rods with a V-shaped cutout.
    [0003] With an axial seal of the fuel injector, which as a rule occurs in the tightening nut of the fuel injector nozzle, and represents a position of embedding as later in the motor vehicle, that is, in the internal combustion engine, the sealing force required on the support in axial direction must be applied in counter-direction. The fuel injector, in its key area, as for example on the nozzle fixing nut, is either compressed downwards or there also applied the required counterforce. When compressing the fuel injector downwards in an axial direction through the clamping area, as a rule an injector specific clamping jaw is arranged in a housing and the fuel injector is pressed by pressing the clamping jaw down against the seal axial.
    [0004] In many cases, in injector test benches, an injection chamber executed, as a rule, positionable is used, which is pressed pneumatically or by a tightening thread against the fuel injector and retained in the key area. The injection chamber support displaceably housed in the injector test bench, i.e. variably positionable, as a rule is performed by different executed adapters specific to the injector or support plates, which are fixed to the test bench of injector.
    [0005] The proposed injector test benches require, in total, distinct respectively injector-specific support plates, adapters or clamping devices in correspondence to the number of variants of the parts to be tested on the injector test bench, i.e., corresponding to the number of variants of the fuel injectors to be tested, which represents a highly satisfactory state. Invention Presentation
    [0006] According to the invention, an injector test bench is proposed, which on the one hand stands out for a considerable reduction of the individual parts required and, on the other hand, guarantees a very easy handling. The injector test bench proposed according to the invention comprises a variable injector support, which comprises a retaining plate, which surrounds a swivel insert therein. The swivel insert of the variable injector holder is configured in such a way that its lateral area moves relative to the inner area of a recess of the stationary holder plate, i.e. a twisting of the swivel insert within the holder holder plate is possible. variable injector, without separating the two moving parts relatively to each other. A twisting of the swivel insert relative to the stationary housed retaining plate is possible clockwise and counterclockwise.
    [0007] By the solution proposed according to the invention, the many different injector-specific support plates, then employed, or required adapters, which must be maintained depending on the number of fuel injectors to be tested, are replaced. Thus, considerable cost savings can be obtained by employing variable injector support instead of different support devices only for passenger vehicle fuel injectors. Furthermore, assembly space can be saved and, due to a considerable reduction in the required components, a considerably improved overall view results. By the swivel arrangement, i.e. the positioning of the swivel insert, within the recesses of the retaining plate, the fuel injector to be tested can be positioned at any angle clockwise or counterclockwise, which is especially of considerable advantage when connecting rigid steel conduits, where test pressure occurs. In solutions hitherto employed with adjustable jaws, where a clockwise or counterclockwise twisting movement is not possible, this cannot be done.
    [0008] Optionally, the stationary retaining plate and the rotating insert of the variable injector holder can be joined together with threads. For this purpose, the retaining plate is provided with an internal thread and the swivel insert with a corresponding external thread. The arrangement then remains rotatable, and allows, in comparison with the solutions previously used, an adjustment of the height of the jaws. The coupling of the torsional movement with the heights or vertical adjustment can be suspended by housing a threaded ring between the stationary retaining plate and the swivel insert, so that an independent adjustment of the rotation and height of the jaws is possible.
    [0009] Advantageously, on a front side of the swivel insert, which is housed by the stationary retaining plate, jaws are housed. It is possible to arrange on the swivel insert a relatively adjustable jaw or preferably both jaws should be arranged on the swivel insert in such a way that both jaws are movable relative to the swivel insert in the horizontal direction. Preferably, the jaws are mounted floating on the swivel insert so that the fuel injector to be tested can be positioned in the middle of the stationary retaining plate notches and on the swivel insert. Being displaceable jaws like screw rods arranged mutually opposed, the position of the longitudinal axis of the fuel injector is dependent on the diameter of the fuel injector. Thus, in conventional injector test benches, only a linear guide of the injection chamber in the vertical direction would no longer be sufficient, so that an additional degree of freedom of movement would be needed for the injection chamber, as a rule, vertically positionable in the bench. test gun. This can be avoided by the solution proposed according to the invention of a floating support for the jaws on the swivel insert.
    [00010] Preferably, the variable injector support is made in such a way that it comprises the stationary retaining plate as well as the swivel insert relative to the retaining plate housed therein. Both components, i.e. the stationary retaining plate and the swivel insert, respectively comprise a continuous U-shaped notch, at whose open end the fuel injector is positionable in the variable injector holder, i.e., threaded into it by the open side. On the upper side of the swivel insert are the floating mounted jaws, displaceable with each other. Due to the floating mounting, a key width, i.e. the distance at which the jaws shaped like a screw shank lie in relation to one another, can be continuously adjusted. The displacement preferably takes place by means of an adjustable clamping wrench, whereby both jaws are joined together and tensionable against each other. By rotating the rotating insert clockwise or counterclockwise, the fuel injector to be tested can be variably positioned, which especially considerably facilitates its union with a test pressure conduit, which can be run rigid.
    [00011] By the solution proposed according to the invention, retaining plates with different widths and angles are dispensed with, whereby the fuel injector to be tested in another way should be positioned in such a way that a rigid test pressure conduit, manufactured , for example, steel, could be connected.

Execution Variants
    [00013] In the representation according to figure 1, an injector test bench can be seen.
    [00014] From the representation according to figure 1, it can be seen that an injector test bench 10 is shown with a holding device 12, in which an injection chamber 14 can be positioned variable in the vertical direction. From the representation according to figure 1, it can be seen that the variable positionable injection chamber 14 comprises an adjustment spring 16, which is arranged between the injection chamber 14 and a fixing device 18. With respect to the fixing position of the fuel injector 28, to be tested, the variable positionable injection chamber 14 can be variable positioned by the clamping device 18 by means of a toggle screw 20 in the vertical direction. The clamping device 18 is guided on guide profiles 22, which extend in a vertical direction along the retaining device 12 of the injector test bench 10. Correspondingly to the adjustment of the clamping device 18, to the action of the adjusting spring 16 , between the injection chamber 14 and the injection nozzle of the fuel injector 28 to be tested a seal can be fitted in axial direction. From the representation according to figure 1 it is further understood that the injector test bench 10 shown therein comprises a housing 24. In the housing 24 is the variable injector support 26, in which the fuel injector 28 to be tested is fixed in the illustration. according to figure 1.
    [00015] Figure 2 shows a perspective reproduction of the variable injector support as used in the injector test bench according to figure 1.
    [00016] From the perspective representation, according to figure 2, it appears that the variable injector support 26 comprises a stationary retaining plate 32, by which a rotating insert is wrapped. Both the stationary retaining plate 32 and the insert 36 housed therein each comprise a notch, as can be seen from the representation in Figure 4. From the representation in Figure 2 it can be seen that on the upper side of the swivel insert 36 are a first jaw 42 as well as a second jaw 40. The two jaws 40, 42 mutually oppose each other like a screw shank. Each of the jaws 40 and 43 is joined by a guide screw 43 or other suitable fastening means with the rotating insert 36, shown only partially in Figure 2. Both the first jaw 40 and also the second jaw 42 respectively comprise openings 52 54, made in the form of an oblong hole, through which the guide screws 43 respectively extend. two jaws 40, 42. Optionally, between both jaws 40, 42 in the region of passage of the fastening screw 41 can be housed a retaining ring or a recessed plate, see an exploded representation according to figure 3.
    [00017] Figure 2 shows that the two guide screws have an additional piece of tool, which can be executed, for example, as an internal hexagon or similar. In addition, the possibility already includes Torx or similar parts here.
    [00018] Corresponding to the horizontal extension in openings 52, 54 executed in the form of an oblong hole in both jaws 40 or 42 results in a horizontal displacement path with respect to the rotating insert 36 enclosed by the retaining plate 32 stationary.
    [00019] Figure 3 shows an exploded representation of the jaws, guide screws as well as the fastening screw.
    [00020] Figure 3 shows that the fastening screws 43, with which the jaws 40, 41 are fixed on the insert 36 and specially positioned, only in the lower segment they have a thread, which immerses in the corresponding thread 42 on the rotating insert 36. In the upper region, the guide screws 43 are executed in the form of a rod, so that a closely tolerated guide is guaranteed between the guide screws 43 and side walls, limiting the openings 52, 54 in the form of an oblong hole, in the jaws 40, 42. Figure 3 also shows in what length the fastening screw 41 is made, which extends through a correspondingly configured opening or thread of the jaws 40, 42. jaws 40 and 42 are spacer 44 or a retaining ring.
    [00021] Figure 4 shows in exploded representation the components, here shown separated from each other, retaining plate and rotating insert of the variable injector support.
    [00022] As can be seen, as shown in Figure 4, both the stationary retention plate 32 has a notch 34, as well as the rotating insert 36, compare reference 38. The two notches 34, 38 are aligned with each other and essentially configured in U-shape, the respectively open sides of the notch 34, 38 overlapping, so that the fuel injector 28 can be inserted from that open side into the variable injector holder 26, which is fixed to the housing 24 of the test bench. of injector 10. As can be seen from the representation of FIG. 4, a lateral area 46 of the rotary insert 36 and an inner area 50 of the stationary retaining plate 32 touch each other. The rotating insert 36 is threaded until it abuts an edge 48 made continuously or partially continuous in the notch 34 of the stationary retaining plate 32 and can be twisted with respect thereto. From the representation according to figure 4 it appears that threads 72 are made mutually opposed on the legs of the rotating insert 36, which limit the notch 38, in which guide screws 43 are screwed, compare the representations according to figures 2 and 3.
    [00023] From figures 5.1 and 5.2 can be deduced horizontal displacements of the jaws of the variable injector support 26.
    [00024] From the representation according to figure 5.1, it appears that, to obtain a first horizontal displacement 56, the first clamp 40, after loosening the guide screw 43 in the first openings 52 in the form of an oblong hole, is displaced at most towards the left, so that the first clamp 40 with respect to the second clamp 42, which is in its original position, is approached thereto. From the representation according to figure 5.2, it can be seen, on the other hand, that it behaves precisely in reverse. To obtain a second horizontal displacement 58, the first jaw 40 is in its original position, i.e., maximum, with respect to the cutouts 34, 38, while the second jaw 42 is displaced to the right after releasing the screw. guide 43 and displacement thereof relative to rotary insert 36 around its maximum adjustment path, so that a second horizontal displacement 58 results in opposition to the first horizontal displacement 56 as shown in Figure 1.
    [00025] In both cases represented in figures 5.1 and 5.2 there is now the possibility of, after tightening the fastening screw 41, to secure the two jaws 40 and 42 against each other.
    [00026] From the representation according to figures 6.1 and 6.2 it is possible to deduce a prestressing of the jaws in relation to each other.
    [00027] Figure 6.1 reproduces the jaws 40 and 42 of the variable injector support 26 in an open position 62. In the open position 62 according to figure 6.1, the two jaws 40 and 42 are at the most recessed from each other, so that results in a maximum distance in the open position 62 between the inner sides of jaws 40 and 42 facing each other. Figure 6.2 shows a prestressing 60 and resulting clamping position 64, where the inner sides of the jaws 40 and 42 are prestressed together as much as possible. When tightening the screw 41 through the two jaws 40 and 42, they, guided by the guide screw 43, move towards each other in the slots 42, 44 in the form of an oblong hole, until the fuel injector 28 shown in figures 6.1 and 6.2 is evenly tightened and positioned centered in the notches 34 and 38 of the retainer plate 32 and the rotating insert 36.
    [00028] From figures 7.1 and 7.2 it can be seen that the two jaws 40 and 42, which are housed by guide screws 43 on the rotating insert 36, perform in a first rotation direction 68 a horizontal twist 66 in the counterclockwise direction. For this purpose, the rotating insert 36 in the stationary retaining plate 32 is rotated counterclockwise in the first clockwise direction 68. Thanks to this variant of execution, an easy connection between the fuel injector 28 tightened by the retaining plates 40 can advantageously be guaranteed. and 42 and a pressure conduit made, for example, of steel, which conducts the test pressure.
    [00029] Figure 7.2 shows, on the contrary, that the jaws 40,42, which are fixed by guide screws 43 to the rotating insert 36, performed a horizontal twist 66, clockwise, that is, extending in the second direction of rotation 70.
    [00030] The twisting possibilities of the rotating insert 36 of the variable injector support 26 facilitate, on the one hand, the manipulation of the injector test bench 10 with variable injector support 26 and allow for quick assembly and disassembly as well as adjustment work , which must be performed when connecting the fuel injector 28 to be tested on the injector test bench 10.
    [00031] From figures 8.1, 8.2 and 8.3 it is possible to deduce the variable injector support in a view from below, in representation in section and in a top view.
    [00032] Figure 8.1 shows the variable injector bracket 26 from below. The rotating insert 36 is guided without play in the stationary retaining plate 32. Due to the absence of play, a precise twist is possible even in a few angular degrees between the rotating insert and the retaining plate 32. From the view shown in Figure 8.1, it appears that the threads 72 on the legs of the twistable insert 36 essentially oppose each other. Parts of the jaws 40 and 42 together with the opening 52, 54 made therein, configured in the form of an oblong hole, are also still identifiable in the bottom view according to figure 8.1.
    [00033] From the top view, according to figure 8.2, it can be seen that, in this state, the jaws 40 and 42 are at most displaced together above the notch 34 of the stationary retaining plate 32, so that a minimum distance between the inner sides of the jaws 40 and 42. The positioning of the jaws 40 and 42 shown in figure 8.2 makes it possible to fix fuel injectors 28 with a small diameter.
    [00034] The set screw 41 is tightened as much as possible, so that the minimum distance between the inner side of the jaws 40 and 42 results.
    [00035] From the representation, according to figures 9 and 9.1, it is possible to deduce a side view of the variable injector support.
    [00036] Figure 9 shows that the variable injector support 26 is constructed relatively flat. On the upper side of the stationary retaining plate 32 of the variable nozzle holder 26 are jaws 40 and 42 shown in the side view, which are positioned by guide screws 43 in a rotating insert 36 at a relative mutual distance. By screw 41 are the jaws 40 and 42 adjusted against each other and fix a fuel injector 28, held between them, in its lateral area. The cross-sectional representation of Figure 9.1 shows that the stationary retaining plate 32 of the variable nozzle holder 26 encloses the rotating insert 36 in a U-shape. the notch 34 of the stationary retaining plate 32 are aligned with each other, so that the fuel injector 28 to be tested can be sent through the opening side of both the notches 34, 38 in the variable injector holder 26.
    [00037] From the representation of figure 10, another form of execution of the retaining plate 32 and the rotating insert 36 can be seen.
    [00038] In figure 10 a stationary retaining plate 32 is shown with the notch 34. The inner area of the stationary retaining plate 32 is provided with an internal thread 76, which houses a twistable insert 36, provided with an external thread 78. The rotating insert 36 has a notch 38 and can be completely or partially screwed into the retaining plate 32. The height of the variable nozzle holder can be adjusted by only partial screwing. This allows a displacement of the vertical position of a fixed fuel injector 28 independently of the displacement possibilities of the injection chamber 14. The vertical displacement per revolution 15 corresponds to the inclination of the screw. This can be established by selecting the thread type, such as fine or coarse thread. The twistable insert 36 has threads 72 on opposing legs of the insert 36, where guide screws 43 are screwed into the jaws 41, 42.
    [00039] In figures 11.1 and 11.2 are represented vertical displacements of the twistable insert 36 of the variable injector support 26.
    [00040] Figure 1.1 represents a rotating insert 36, screwed only partially into the stationary retaining plate 32. A fully bolted swivel insert 36 is shown in figure 11.2. The variable injector support 26 has, in both representations, different vertical positions, whose path difference is given by the number of revolutions of the rotating insert 26 and the inclination of the threads 76, 78. The jaws 40 and 42 are mounted floating by the screws of guide 43 on the rotating insert 36 and present possibilities of horizontal adjustment as shown in figures 5 and 6. A horizontal twist of the rotating insert 36, as shown in figures 7.1 and 7.2, is also possible, with the horizontal twist and the vertical displacement being joined together by threads 76 and 78. With predetermined horizontal twist, the vertical displacement can be adjusted in scales of respectively one complete rotation of the rotating insert 36.
    [00041] From the representation of figure 12 it can be seen another embodiment of the variable injector support 26, in which between the retaining plate 32 stationary and the rotating insert 36 is housed a screw ring 80.
    [00042] In Figure 12, the stationary retaining plate 32 with an internal thread 76 is shown. In the stationary retaining plate 32 is housed a screw ring 80 provided with an external thread 81. The screw ring 80 also has a internal thread 82, which houses the rotating insert 36, provided with an external thread 78. The rotating insert 36, the retaining plate 32 and the thread ring 80 have notches 35, 38, 84. The thread ring 80 can be completely or partially bolted to the stationary retaining plate 32. Likewise, the rotating insert 36 can be completely or partially screwed into the screw ring 80. By partially screwing the screw ring 80 or the rotating insert 36, the height of the variable injector support 26 can be adjusted. of a fuel injector 28 subject independently of the displacement possibilities of the injection chamber 14. By the screw ring 80 housed, both the vertical position or the height as well as the horizontal torsion of the rotating insert 36 can be adjusted without scaling. revolution corresponds to the inclination of the thread. This can be fixed by selecting the type of thread, such as thick or thin thread. It is possible to select for the screw connection between the stationary retaining plate 32 and the screw ring 80 a different thread inclination than the screw joint between screw ring 80 and the rotating insert 36. It is also possible to provide only for the screw ring 80 an external thread or an internal thread, and slidingly mount the respective other side. The rotating insert 36 has threads 72 on opposing legs of the insert, wherein guide screws 43 for jaws 41, 42 are screwed.
    [00043] In figures 13.1 and 13.2 are represented vertical displacements of the rotating insert 36 of the variable injector support 26.
    [00044] Figure 13.1 represents a threaded ring 80 only partially screwed into the stationary retention plate 32 and an insert 36 only partially screwed into the threaded ring 80. In figure 13.2 is represented the variable injector support in the minimum possible vertical position. The rotating insert 36 is fully screwed into the screw ring 80 and this is fully screwed into the stationary retaining plate 32. The variable injector support 26 presents in both figures 13.1 13.2 different vertical positions, whose path difference is given by the number of revolutions of the rotating insert 36 or of the thread ring 80 and by the inclination of the threads 76, 78, 81 and 82. Jaws 40 and 42 are mounted floating by guide screws 43 on rotary insert 36 and have horizontal adjustment possibilities as in figures 5 and 6. A horizontal twist of rotary insert 36, as shown in figures 7.1 and 7.2, is also possible. By the screw ring 80 the horizontal twist is separated from the vertical displacement, so that the horizontal twist and the vertical position can be adjusted steplessly and independently of each other.
    [00045] By the solution proposed according to the invention, considerable cost savings can be obtained, especially by using the variable injector support 26. The many retaining plates or different adapters previously required can be dispensed with without replacement, as well as the retention support for them. Due to the considerable reduction of the components to be employed in an injector 10 test bench, a better overview results. The possibility of horizontal rotation 66 by twisting the rotating insert 36 relative to the stationary retaining plate 32 of the injector holder 26 allows for positioning the fuel injector at almost any angle. This is especially advantageous when connecting rigid test pressure lines. By the floating support of the jaws 40 and 42 the fuel injector 28 can especially be centrally positioned. The floating assembly allows for an alignment of the fuel injector in relation to the injection chamber, usually vertically positionable without the need for its lateral displacement, so that only a linear guide of the injection chamber is enough, as tolerances between the fuel injector 28 to be tested and the injection chamber 14 only positionable in the vertical direction thanks to the floating mounting of the jaws 40 and 42 can be compensated. The vertical displacement, possible in addition to the vertical positioning of the injection chamber 14, the variable injector holder 26 by the use of threads on the stationary retaining plate 32, the rotating insert 36 or an additional screw ring 80 facilitates the exact adjustment of the distance vertical between the fuel injector 28 and the injection chamber 14 and can, when only a few displacement paths are needed, totally replace displacement possibilities in the injection chamber 14.
