    Technical area
    [001] The present invention relates to a filtration system comprising a filter housing and a filter element that can be used for the filtration of air, and to a filter element and the use thereof for such a filtration system . In particular, the present invention relates to an air filter system and an air filter element, and the use thereof for such an air filter system for the intake air of internal combustion engines.
    [002] Filter elements are used to filter liquid flows or gaseous media. They are used, for example, in the filtration of an air stream that is carried to an internal combustion engine. In this case, it is necessary to free it from particles in suspension. Such air filters, for example, for trucks, construction machinery, agricultural machinery or also ship engines, need to be built reliably and robustly, since during operation they are exposed to large mechanical stresses.
    [003] Filters, as a rule, have a housing with an upper part of the housing, and a replaceable filter element can be embedded in the housing. In general, the filter element is tube-shaped and is retained in the closed housing due to friction with the help of a seal. The state of the art
    [004] US 6 599 342 B2 discloses a filter arrangement where a filter holder has at least one through opening that serves as a sealing seat for a filter element equipped with an adapter collar.
    [005] As a seal between the housing or housing cover and the filter element, for example, polyurethane foam (PU), also called PUR foam. However, such polyurethane foam relaxes after heat storage (artificial support) or the action of high temperature or temperature change.
    [006] In other words, the polyurethane foam, after a heat storage, becomes without forces. This fact, with filter elements kept in the closed housing due to friction, always makes it possible in case of excitation by oscillation of the arrangement consisting of the housing parts with the upper housing, seal and filter element greater critical movements occur between the various components. Such oscillation excitation can occur, for example, when operating a motor vehicle where a filter is mounted. In this case, a rotating movement of the filter element can occur especially during operation, causing the sealing materials to be strongly requested, and particles can pass through. The presentation of the present invention
    [007] Therefore, the present invention has the task of creating an improved air filter system and an improved air filter element.
    [008] This task is solved with an air filter system, with the air filter element to be mounted on such an air filter system and the use of it according to the invention.
    [009] Other advantageous embodiments of the filter element are indicated in the embodiments.
    [0010] IN ACCORDANCE WITH THIS, THE AIR FILTER SYSTEM SERVES Especially for the intake air of internal combustion engines and comprises a housing and at least one air filter element to filter the air. Preferably, the housing comprises an upper part of the housing with an especially central pure air outlet to derive purified pure air in the housing's air filter element, and a sealing region preferably made as a sealing groove for the junction especially with due closure to the shape, with a cylindrical seal, especially acting radially from the air filter element and to fix the air filter element.
    [0011] The sealing region preferably presents a cylindrical contact surface that extends from the upper part of the housing to the internal space of the housing that surrounds or surrounds the fresh air nozzle. The seal of the air filter element with a sealing surface can preferably be adhered radially sealingly. The contact surface can also be arranged axially offset from the fresh air nozzle.
    [0012] In one embodiment, the sealing groove is an annular sealing groove that surrounds the fresh air nozzle, open to the internal space of the housing. This serves to engage an annular sealing rib that extends axially from the filter element, the sealing groove having a cylindrical contact surface where a sealing surface of the sealing rib can be touched, especially in a way radially sealing. In addition, the sealing groove has a support surface preferably directed towards the contact surface which has at least one extension that protrudes from the support surface towards the sealing surface. Also preferably, the sealing rib has a second surface that is opposite to the sealing surface, which in a peripheral annular manner has several cavities in the radial direction, the at least one extension engaging in one of the cavities respectively.
    [0013] Extension and cavities are preferably executed in such a corresponding way that the cavity surrounds the extension with closure due to the shape.
    [0014] In this way, in a compact construction, the position of the filter element can be protected in such a way without additional parts that during operation, the rotation of the filter element no longer appears, since these means are arranged in the the upper part of the housing in the region of the fresh air nozzle, with advantage, also with the filter element fixed to the rotation proof, the housing cover can still be rotated, even after it is already installed, but not yet permanently fixed. This makes it easier for the operator, after changing the filter element, to orient the cover in its position independently. This is advantageous especially when a dust discharge opening that is arranged in the cover needs to be oriented downwards in the direction of the force of gravity in order to guarantee a reliable dust discharge.
    [0015] In one embodiment, the contact surface of the sealing groove is cylindrical and is arranged, for example, radially externally or internally in the sealing groove. Preferably, the support surface is also cylindrical or conical, for example, with a diameter that increases towards the internal space of the housing. A cylindrical shape can support a radial support effect to increase the radial sealing effect, a conical shape can reduce the operating forces that occur when changing the filter.
    [0016] The extension or extensions on the support surface may, for example, take the form of a cylinder segment whose central axis extends outside the support surface and in essence parallel to the central axis of the housing. As an alternative to this, it is possible to imagine the shape of rounded triangular prisms that essentially extend parallel to the central axis of the housing.
    [0017] An air filter element for detachable mounting in an air filter system housing according to the present invention preferably comprises an annular sealing rib that extends axially from the filter element which is executed in such a way which can engage the sealing groove on the housing side with a contact surface and a support surface opposite to the first. In this case, the sealing rib preferably has a sealing surface that can abut radially sealing against the contact surface of the sealing groove and also a second surface that is opposite the sealing surface with several cavities spaced apart from each other. peripheral ring mode. The cavities are preferably made in such a way that when the air filter element is mounted in the housing, they can encircle especially with closure due to the shape an extension projecting from the support surface of the sealing groove towards the contact surface .
    [0018] The second surface of the sealing rib is preferably adapted in such a way that it can be supported radially on the supporting surface.
    [0019] In a preferred embodiment, the cavities are arranged on the second surface evenly spaced from each other. In this way, the air filter element can be mounted in all those positions in the housing, in which one of the cavities corresponds with the extension or extensions. In this, preferably, a large number of cavities is provided, preferably ten or more, so that the filter element can be mounted in ten or more rotation positions. When fitting the filter element, the correct position can be found with a small rotation movement.
    [0020] In an embodiment, the cavities and / or the extension / extensions are performed essentially in the form of a cylindrical segment, the central axis of which is radially outside the sealing rib or the supporting surface, and in essence it will parallel to the central axis of the filter element or housing. For the case that the supporting surface or the second surface are conical, the central axes of extensions or cavities preferably go essentially parallel to the outer face of the cone.
    [0021] In an embodiment, the cavities and / or the extension / extensions are performed essentially in the form of rounded triangular or polygonal prisms that extend in essence towards the central axis of the air filter element, whose direction of extension (direction of travel) in essence goes parallel to the central axis of the filter element or housing. In the case that the supporting surface or the second surface is conical, the extension directions (displacement directions) of extensions or cavities preferably go according to the essence parallel to the external face of the prisms. The basic triangular shape can be transformed through strong rounding of the tips and transition areas of the support surface into a round shape, as described above.
    [0022] The cylindrical shape of the sealing surface can preferably be made as a round cylinder, especially as a circular cylinder, elliptical cylinder or oval cylinder. In this case, the shape preferably constitutes the outer circumference of the air filter element. However, a polygonal shape can also be chosen, especially a rectangular shape.
    [0023] Preferably, the air filter element is made as a round filter element comprising a closed annular filter bellows, folded into a zigzag shape that surrounds a central internal space. The filter bellows are sealed at their axial ends by end discs, and a final disc has a central annular opening for inlet and outlet, where the seal is arranged to separate the raw side from the purified side. However, the air filter element can also have two closed ring filter bellows, folded in the shape of a zigzag that are arranged inside each other, being joined together, so that a filter bellows can be traversed radially from the outside in. , and the other filter bellows, can be traversed radially from the inside out. An air filter element with channels extending in the direction of the flow that are formed is also imaginable by the fact that alternately a smooth layer of filter medium and a wavy layer of filter medium are placed on top of each other, and the channels formed between them they are closed on alternate sides.
    [0024] As a filter medium, respectively, a flat porous filter medium, for example, individual layers or combinations of cellulose media, fiberglass media, non-woven fused or spun synthetic fibers.
    [0025] In one embodiment, the sealing groove is formed by a roughing or groove in the housing that surrounds the purified air nozzle in the shape of a ring, especially in the upper part of the housing.
    [0026] In one embodiment, the sealing surface is formed by a cylindrical wall, radially internal or external to the roughing or groove.
    [0027] The contact surface is preferably provided in the housing, pointing radially outwards, especially towards the air filter element.
    [0028] Preferably, the filter element is supported and retained in the position in the end housing in the region of its final bottom disk by the cover.
    [0029] Preferably, a central air-permeable tube is arranged in the housing for the radial support of the replaceable filter element and, preferably, is joined to the housing in a non-separable manner, for example, in the region of the purified air nozzle. The central tube is arranged radially inside the filter element, in order to stabilize it during a passage from radially outside to radially inside.
    [0030] The present invention also relates to an air filter element for detachable mounting in an air filter system housing especially in accordance with the present invention, where the air filter element comprises a seal for the retention of the air filter element in the housing, and to seal a space between the air filter element and the upper part of the housing, when the air filter element is mounted in the housing so that it can be removed, the The seal can be joined to the seal groove of the upper part of the housing with closure due to the shape.
    [0031] The closing due to the shape of preference is made in a radial direction, that is, a part of one of the components, preferably of the housing, for example, the extension, radially engages the other component, preferably of the filter element of air. In this way, a closed junction is obtained due to the shape that makes it difficult for the filter element to rotate in the seal seat.
    [0032] The filter element is preferably an air filter element, for example, for the combustion air filtration for an internal combustion engine. However, the present invention can also be used in liquid filters, for example, oil filters or fuel filters.
    [0033] The seal, preferably at least partially or completely, is made of a melt, for example, especially of a foamed PUR material. In particular, the seal and / or the materials of the filter element or housing are prepared for operating temperatures between minus 30 ° C and 90 ° C. Preferably, the seal is produced entirely with a final disc of the same material. More preferably, the final disk is made of the melt and during the casting it is sealed together with the filter bellows.
    [0034] In addition, the seal may have at least one reinforcement element to make the seal rigid.
    [0035] The sealing rib of the aforementioned air filter elements can extend axially, for example, or from a final surface of a filter media construction, for example, from the front face of an annular filter media bellows closed, folded into a star shape, or from a final disc construction there. However, the sealing rib can also be formed by the final disc construction itself which is the end of an axial end on the side of the front face of a closed, star-shaped bellows filter media. As a result, the sealing surface and the second surface can be arranged either axially outside the area of the filter medium or in a region surrounding the filter medium still at least in part.
    [0036] In the seals according to the present invention, the second surface of the sealing rib serves to generate a clamping pressure on the sealing surface arranged especially radially inside, when the filter element is being assembled or is already assembled. This second surface of the sealing rib is preferably supported radially on the supporting surface which is, for example, annular in the sealing groove. The cavities that are not engaged with an extension reduce the pressure or the mechanical resistance that is noticeable in the assembly of the filter element. For this reason, it is preferred that a smaller number of extensions is provided on the support surface than cavities in the filter element. Only a prolongation is especially preferred.
    [0037] The present invention also relates to a process for replacing a filter element in an air filter system according to the present invention, where the housing is opened, especially by separating a lower part of the the upper part of the housing, then an air filter element, especially in accordance with the present invention, is removed from the housing, and then an air filter element in particular is fitted in the housing, in such a way that the sealing rib is closed with closure due to the shape with the sealing groove of the upper part of the housing.
    [0038] When assembling, the sealing of the filter element is positioned and if a cavity no longer corresponds with the extension, it is turned slightly, until it can be inserted completely into the sealing groove. When fitting, the sealing surface of the sealing rib abuts radially sealingly to the corresponding contact surface of the housing.
    [0039] Other possible implementations of the present invention also comprise combinations not explicitly mentioned of features or embodiments described above or below. In this, the person skilled in the art will also add individual aspects such as improvements or additions to the respective basic form of the present invention.

    [0046] In the figures, the same elements or with the same functions, if there is nothing contrary, take the same references. The embodiments of the present invention
    [0047] In the following, the present invention is described with the help of a filter for the combustion air of an internal combustion engine, such as, for example, a motor vehicle. Corresponding filter elements can be equipped, instead of for air filtration, for example, for the filtration of another gaseous medium or also of a liquid medium, especially oil.
    [0048] The designs shown in the figures are used in particular for the filtration of intake air for internal combustion engines and comprise a housing and at least one air filter element to filter the air. As shown in figures 1 and 2, the filter 1 according to the first embodiment comprises a housing 10 with an upper part of the housing 11 which is joined to a lower part of the housing 13 (cover). Fig. 2 shows in detail a variation of the cutout which in Fig. 1 is marked with 60. Housing 10 in Fig. 1 is a housing 10 of two parts. The lower part of the housing 13 is retained in the upper part of the housing 11, for example, with clamps. A polluted air outlet 15 is arranged on the upper part of the housing 11, with which polluted air, non-purified air, can be introduced into the housing 10. In the section view shown, the region with the inlet opening is cut and thus is not visible. A polluted air outlet can be made with a radial or tangential inlet. In the upper part of the housing 11 there is also a clean air nozzle 16 with which the clean air, the unpolluted air, can be conducted out of the housing 10 in the flow direction indicated by the white block arrow. At the bottom of the housing 13 there is a discharge valve 17 with which the particles that were contained in the polluted air can be removed from the housing 10. However, active aspirations can also be provided. The housing 10 has on the upper part of the housing 11 and the lower part of the housing 13 several ribs 18 which serve, for example, as reinforcement of the housing 10 or the upper part of the housing 11 or the lower part of the housing 13. In the interest of the best visibility, in Fig. 1 not all ribs 18 have a reference. A filter element 30 is installed in the housing 10 for filtering the air. A central tube 14 in the shape of a hollow cylinder and a grid is arranged in the housing 10, so that the air filtered by the filter element 30 can pass through it radially. The central tube 14 is preferably fixed at an axial end in the housing 10 in the region of the fresh air nozzle 16, for example, as shown in Figs. 1 and 2, by means of an interlocking lock which preferably is not separable or not separable without being destroyed. The filter element 30, in assembled condition, surrounds the central tube 14. During operation the central tube 14 can radially support the filter element 30 and thus prevent a collapse when the differential pressure is too high on the filter element 30.
    [0049] The housing 10 comprises a sealing region, preferably made as a sealing groove 350, for the junction mainly with closure due to the shape of a cylindrical seal 33, especially of radial effect, of the air filter element 30, and for the attachment of the air filter element 30. The sealing region 350 preferably has a cylindrical contact surface 351 (Fig. 2) that extends from the upper part of the housing into the internal space of the housing that surrounds the air nozzle. fresh air 16. The seal 33 of the air filter element 30 with a sealing surface 337 can be placed radially sealingly with the sealing surface 337. The contact surface can also be axially offset with respect to the clean air nozzle, as shown in Figs. 1 and 2.
    [0050] In the embodiment shown, the sealing groove 350 is an annular sealing groove that surrounds the clean air nozzle, axially open to the internal space of the housing. It is used for locking engagement due to the shape of an annular sealing rib 332 that extends axially from the filter element, with the sealing groove 350 having the cylindrical contact surface 351 on the radially internal side, where it can be radially abutting the sealing surface 337 of the sealing rib. In addition, the sealing groove has a support surface 352 facing the contact surface, that is, arranged on the radially outer side, which has at least one extension 353 projecting from the support surface 352 towards the surface contact 351. The sealing rib preferably has a second surface 338 which is opposite the sealing surface 337 which is peripherally ring-shaped and has several cavities 339 in radial direction, the at least one extension of which can respectively engage in one of the cavities when the filter element in the mounting direction has reached its final axial position in the housing 10. The extension 353 and the cavities 339 are executed in such a corresponding way that the cavity involves the extension with closure due to the shape. In this, the cavities 339 preferably imitate the shape of the extension 353. In the case of an elastic sealing compound for the seal 33, for example, of polyurethane, the cavities 339 can be made with a slight excess of dimensioning so that they are slightly pressed into the assembly by extension 353 on the housing side. In this way, in a compact construction, the position of the air filter element 30 can be guaranteed in such a way without additional parts that during operation a rotation of the air filter element 30 does not occur. Since these elements to prevent rotation are arranged in the upper part of the housing 11 in the region of the fresh air nozzle, it can also advantageously even with the air filter element 30 fixed against rotation, the lower part of the housing 13 can still be rotated after it has already been placed, but not yet permanently fixed. This makes it easier for the operator, after replacing the filter element, to align the cover 13 regardless of its position. This is advantageous especially when a dust discharge opening 17 arranged in the lid needs to be aligned vertically downwards in the direction of the force of gravity, in order to guarantee a reliable dust discharge.
    [0051] As shown in Fig. 2, the contact surface 351 of the sealing groove 350 is preferably cylindrical and is arranged on the radially inner side of the sealing groove. The support surface 352 is also cylindrical and preferably, as shown, it is slightly tapered, with a diameter that increases towards the internal space of the housing 12. The tapered shape can reduce the handling forces that occur when replacing the filter.
    [0052] The extension 353 on the support surface 352 is carried out, for example, as shown, in the form of a triangular prism that essentially extends parallel to the central axis 20 of the housing 10 or the contact surface 351. The tip that extends into the sealing groove 350 and also the passages for the supporting surface 352 are rounded. From Fig. 2 it becomes visible that the basic triangular shape turns into a round shape of a cylindrical segment due to the strong rounding of the tips and passage areas to the support surface 352.
    [0053] The air filter element 30 for separable mounting in the housing 10 of the filter 1 shown comprises an annular sealing rib 332 extending from the filter element that is configured in such a way that it can engage with the sealing groove 350 on the housing side with the contact surface 351 and the support surface 352 opposite the first. The sealing rib 33, in this case, preferably has, as shown in Figs. 2 to 4, a sealing surface 337 which can be radially sealingly abutted against the contact surface 351 of the sealing groove 350, and also a second surface 338 opposite the sealing surface with several cavities 339 arranged spaced apart from each other, in a peripheral annular way. The cavities, in this case, preferably, and as already shown, are configured in such a way that when the air filter element 30 is mounted in the housing 10 they can involve, especially with closure due to the shape, an extension 353 that protrudes from the support surface 352 of the sealing groove 350 towards the contact surface 351. The second surface 338 of the sealing rib 332, in this case, as shown, is adapted in such a way that it can be radially supported on the support surface 352. The cavities 339, preferably, as shown, are arranged on the second surface 338, uniformly spaced from each other. In this way, the air filter element 30 can be mounted in all those positions in the housing 10 where one of the cavities 339 coincides with the extension 353. In this, a large number of cavities is preferably provided, preferably ten or more, for example , as can be seen in Fig. 3, 13 cavities. In this way, the filter element can be mounted in ten or more rotation positions. When placing the filter element 30 in the mounting direction 35, the correct position can be found by means of a small turning motion.
    [0054] As indicated in Figs. 2 to 4, the cavities 339 and / or the extension 353 are essentially executed in the form of rounded triangular or polygonal prisms that in essence go parallel to the central axis of the air filter element, whose direction of extension (direction of displacement) in the essence goes parallel to the central axis 20 of the filter element 30 or of the housing 10. In the event that the support surface 352 or the second surface 338 are conical, the directions of extension (directions of displacement) of extensions or cavities preferably go in essence respectively parallel to the outer face of the prisms.
    [0055] The cavities 339 and / or the extension 353, as an alternative, can in essence be executed in the form of a cylindrical segment, the central axis of which is located radially on the outer side of the sealing rib 332 or the supporting surface 352, and which in essence runs parallel to the central axis 20 of the filter element 30 or of the housing 10. In the event that the support surface 352 or the second surface 338 is conical, the central axes of extensions or cavities are preferably in parallel to the outer face of the cone.
    [0056] The cylindrical shape of the sealing surface 337 can preferably be performed as a round cylinder, especially as a circular cylinder, elliptical cylinder or oval cylinder. In this case, the shape preferably follows the external or internal circumference of the air filter element, for example, also with a radial distance from the circumference, as shown in Figs. 2 to 4. However, a polygonal shape can also be chosen, especially a rectangular shape.
    [0057] The air filter element 30, as seen in all Figs., Is preferably executed as a round filter element comprising a closed annular filter bellows 31, folded in a zigzag shape that surrounds a central internal space 32 . The filter bellows 31, at their axial ends, is sealed by end discs 36, 313, the open end disc 36 having an annular central outlet opening 37 where seal 33 is arranged to separate the polluted side 40 from the purified side 50. As a filter medium for the filter bellows 31, a flat, porous filter medium is used, for example, individual layers or combinations of cellulose media, glass fiber media, non-woven of fused or spun synthetic fibers.
    [0058] The air filter element 30 for separable assembly in the housing 10 of the air filter system, is preferably fixed in the housing 10 in the final disk 36 opened by means of the seal 33, thus sealing in the housing 10 the polluted side 40 against the purified side 50, the seal 33 with the sealing rib 332 being able to be joined with closure due to the shape with the sealing groove 350 of the upper part of the housing 11.
    [0059] The closing due to the shape preferably occurs in a radial direction, that is, a part of a component, preferably of the housing, engages radially in the other part, preferably the filter element, for example, as shown in Figs. 1 to 2, the extension 353 engages in one of the cavities 339 which, therefore, surrounds the extension. This results in a lockable joint due to the shape that makes it difficult for the filter element to rotate in the sealing seat.
    [0060] The final discs 36, 313 are preferably at least partially or totally made of a melt, for example, a PUR material, especially foamed. In particular, the seal 33 or the sealing rib 332 is made entirely and with the same material as the final disc 36 open.
    [0061] In the seals 33 shown in Figs., The second surface 338 of the sealing rib 332 serves to generate a clamping pressure on the sealing surface 337 specially arranged radially inside, when the filter element 30 is or is being mounted within this housing 10. In this, this second surface 338 of the sealing rib 332 is preferably supported radially on the support surface 352 of the sealing groove 350. The cavities 339 that are not in engagement with an extension reduce pressure or resistance mechanic that is noticeable during the assembly of the filter element. Therefore, it is preferred that a smaller number of extensions is provided on the support surface than cavities in the filter element, preferably as shown in Figs., Only one extension is provided.
    [0062] For the exchange of an air filter element 30 in an air filter system 1, the housing 10 is opened, especially by separating a lower part of the housing or cover 13 from the upper part of the housing 11, then , an air filter element 30 is removed from the housing and then a new air filter element 30 is mounted in the housing 10, in such a way that the sealing rib 332 is closed together due to the shape with the sealing groove 350 from the top of the housing. In this, the seal 33 of the filter element 30 is placed, and if a cavity 339 no longer coincides with the extension 350, it is slightly rotated until it can be inserted completely into the sealing groove 350. On insertion, the sealing surface 337 of the sealing rib 332 abuts radially sealingly to the corresponding contact surface 351 of the housing 10.
    [0063] Fig. 3 shows in a full three-dimensional view a filter element 30 for use in an air filter system according to the present invention according to an example of execution. The filter element 30 of Fig. 3 is a hollow cylindrical body which on its outer circumference has several adhesive threads 312 for the stabilization of folds which, in the interest of better visibility, are not all endowed with references in Fig. 3. down in Fig. 3, the filter element 30 is terminated by a final bottom disk 313. At the end of the filter element 30 opposite the final bottom disk 313, the seal 33 is arranged. The seal 33 has a seal rib 332 with a sealing surface 337 of radial effect on the inner side and a second surface 338 of the sealing rib 332. The seal 33 has several cavities 339 on the second surface 338 which, in the interest of better visibility, are not all provided with references. The cavities 339 are arranged along the circumference of the sealing rib 332 side by side. Fig. 4 shows the shape of the seal 33 with the cavities 339 in enlarged detail.
    [0064] In the seal 33, the outer side of the seal 338 preferably serves to generate a clamping pressure on the sealing surface when the filter element 30 is or is being mounted in the housing 10 in the direction of assembly 35. The cavities 339 reduce the pressure or the mechanical resistance that is noticeable during the assembly, and serve to close with zipper due to the shape of an extension on the housing side.
    [0065] All of the above-described examples of filter 1, filter element 30 and housing 10 can be used separately or in any combination. In this case, especially the following modifications are imaginable.
