TECHNICAL STATUS
    [004] An air filter of an air intake section of a combustion engine, of a motor vehicle, known on the market, has a filter housing that is constituted by a housing top and a housing cover. The housing cover can be removed from the top of the housing for the purpose of opening the filter housing. The filter housing has an inlet for air to be purified and an outlet for purified air, within the filter housing, a round filter element is integrated in such a way that it separates the inlet from the outlet. The round filter has a means for filtering the air that surrounds, in a closed form, an inner element compartment, ie an element shaft. The filter is interchangeably integrated within the filter housing.
    [005] The invention has as its object to produce an air filter, a filter element and a filter housing of an air filter of the species initially mentioned, in which, the positioning and/or a fixation of the filter inside the filter housing can be improved, especially simplified. DESCRIPTION OF THE INVENTION
    [006] According to the invention, this task will be solved by the fact that the filter, on an outer side away from the inner element compartment, at least on an axial front face in relation to the element axis, has at least one support element that has at least one lateral support face, having at least one cylindrical segment and/or a segment with changeable cross section in the direction of a main axis, its main axis projecting in an axial direction or parallel to the element axis and with which the support element abuts at least against a corresponding support segment on the side of the filter housing, at least transversely to the element axis.
    [007] According to the invention, at least one support element, and with this the filter itself, abut at least in a transverse direction to the element axis, especially in a radial or tangential direction to the axis of element or radial to another axis and is parallel to the element axis. In this way, the filter can be positioned and fixed in a radial direction, that is, in the direction of the element axis. By virtue of the arrangement of at least one support element, the filter may be mounted on the outside of the front face, altogether in the axial direction. Thus, it can be inserted space-saving inside the filter housing.
    [008] With the filter assembled correctly, the element shaft can advantageously project in a coaxial direction to a shaft of the filter housing. In this way, as a whole, the air filter can be made coaxial. In this way, the space requirement of the air filter can be further reduced. The element axis and/or the housing axis can advantageously extend axially towards a filter mounting direction relative to the filter housing, especially with respect to a housing section with at least one bearing segment. Thus, the filter can simply be fitted axially into the filter housing. The filter may be specially fitted in axial direction in a corresponding housing section, especially in a top of the filter housing. Advantageously, one of the housing sections, especially the housing cover, can be fitted axially over the filter and over the other housing section.
    [009] Advantageously, at least one supporting element can abut on the filter housing additionally in axial direction with respect to the element axis. In this way, too, the axial position of the filter can be predetermined. Advantageously, the filter may be axially clamped and retained between two opposing support segments of the filter housing.
    [0010] At least one side bearing face may preferably have a fully cylindrical shape. A cylindrical shape enables an optimized transfer of force from at least one lateral bearing face or at least one lateral bearing face radially to a main axis of at least one lateral bearing face. Alternatively, the supporting side face may have a changeable cross section along a main axis. In this case, the contour and/or dimensions of the cross face can be changed. At least one supporting side face, especially, can have a fully conical shape. With a conical shape, it can be facilitated the fitting of at least one support segment, at least on one side support face and/or the fitting of at least one support side face, at least on one segment of support. At least one supporting side face can also consist of cylindrical segments and segments of changeable cross section, especially conical segments. At least one supporting side face can advantageously - at least in segments - be straight-cylindrical and/or straight-conical. At least one lateral support face can present, at least, oblique-cylindrical and/or oblique-conical shaped segments.
    [0011] At least one supporting side face can advantageously limit an oval, flat-oval or round cross section. It can also limit another cross section, especially an angular one.
    [0012] At least one side bearing face may be closed on the circumference. It may also have interruptions. For example, the support side face can consist of lateral faces of several support elements or the support element can have slots which form the interruptions of the support side face.
    [0013] At least one support element may also have more than one support side face, preferably two support side faces. In this way, it becomes possible to improve support.
    [0014] Advantageously, at least one support element may have a hollow cylindrical or glove-like segment. A radially inner bearing side face can be configured, with respect to the main axis of at least one bearing element, by the radially inner circumferential side of the hollow cylindrical segment or in the form of a sleeve. Alternatively or additionally, an external radial bearing side face can be configured by the radially external circumferential side of the hollow cylindrical segment or in the form of a sleeve.
    [0015] Advantageously, with the filter assembled correctly, the hollow cylindrical or sleeve-shaped segment can be fitted into a corresponding front groove, especially a counter-support groove of at least one support segment. The groove can be considered as a hollow space of the support segment is open towards the free front face of the support segment. The radially inner bearing side face of at least one bearing element can abut a corresponding radially inner bearing counterface of at least one bearing segment. Alternatively or additionally, the outer radial bearing side face of at least one bearing element can bear on a corresponding outer radial bearing counterface of at least one bearing segment.
    [0016] Alternatively, at least one bearing element may have a front groove, especially a bearing groove extending circumferentially with respect to the main axis. Advantageously, the groove can be located on a front face of at least one support element, spaced apart from the filter. The groove can be considered as a hollow space of at least one support element which is open towards its free front side. A radially inner bearing side face can be configured as the radially inner circumferential face of the groove with respect to the main axis of at least one bearing element.
    [0017] Alternatively or additionally, a radially external support side face may be embodied as a radially external circumferential side of the groove relative to the main axis of at least one support element. A respective hollow cylindrical or sleeve-shaped segment of at least one bearing segment can be fitted in the front groove of at least one bearing element. The radially inner bearing side face of at least one bearing element may abut a corresponding radially inner bearing side counterface of at least one bearing segment. Alternatively, or additionally, the outer radial bearing side face of at least one bearing may bear on a corresponding outer radial bearing side counterface of at least one bearing segment.
    [0018] Advantageously, the filter housing can consist of at least two housing sections. To open the filter housing, the two housing sections can advantageously be separated completely or partially. One of the housing sections can be especially the top of the housing. On top of the housing the filter may be integrated. The top of the housing may advantageously be coaxial with an axis of the housing. Advantageously, it can have a mounting opening for the filter, coaxial with the axis of the housing. In this way, the filter can be mounted simply, in axial direction with respect to the axis of the housing inside the top of the housing through its mounting opening. Another section of the housing can advantageously be the housing cover. With the housing cover, the mounting opening at the top of the housing and therefore the filter housing itself can be closed. At least one entrance and at least one exit can be found in the same or different sections of the accommodation.
    [0019] Advantageously, a supporting seed can be found in one of the housing sections. Advantageously, at least one support segment can be found in the housing cover. Thus, it becomes possible to simplify the positioning of the filter element and/or the assembly of at least one support element with at least one support segment.
    [0020] Advantageously, the filter can support at least one support element on the opposite front side, in the other section of the housing.
    [0021] Advantageously, at least one support element or at least one support segment may not have a sealing function. In this way, the support function can be reciprocally separated, being respectively optimized. A corresponding sealing function can be allocated to at least one other set of modules, separate from at least one support element and at least one support segment, being specifically optimized. In another version, the support element and the support segment can have a sealing function. This will be, for example, necessary when the support segment has a transfixing opening towards the external environment in the housing.
    [0022] Advantageously, at least one support element may be elastic, at least in part. In this way, with at least one support element, any tolerances for mounting the filter inside the filter housing can be simply compensated for. Furthermore, at least one support element can additionally serve as a vibration damper, especially in the operation of the air filter. Advantageously, at least one support element can be made of an elastic plastic, especially polyurethane (PUR). The polyurethane can be joined with the filter medium in a simple way, directly or indirectly, through a corresponding connecting body, especially an end body or an end plate. At least one support element can advantageously be foamed next to or on the filter means or the connecting body. The support element can also have a core of an inelastic plastic that can be wrapped with an elastic plastic, being specially foamed so that its stability will be increased. Alternatively, the support element could also consist entirely of an inelastic plastic.
    [0023] Advantageously, the filter is configured as a hollow element with a filtering means and surrounds an inner element compartment relative to the element axis. The support element will then be found on an outer side of the front face of the filter, away from the inner element compartment. Advantageously, the inner element compartment may be closed on the front side of the filter, where at least one support element is located. In this way, a draft of air from the inner element compartment or into the inner element compartment can be avoided at that point. Thus, you can get the air through the filter. Air may pass through the filter in radially outward to radially inward direction within the element's inner compartment, or it may exit the compartment in the reverse direction. Air can flow through a corresponding through-flow opening on the other front side of the filter, entering the inner element compartment or leaving this compartment. In an alternative configuration, the filter may consist of alternately closed channels. A filter of this type is also known as a floating medium. Elements made up of a filter of this type are also called compact elements. In this case, there is the inflow in the axial direction from one front face to another front face, and on one front side the air penetrates into a channel opened for it on this front face, and flows out on the opposite front face through another open channel on that front face.
    [0024] With respect to the filter element, it may advantageously be a hollow filter, especially a round filter with a round cross section, an oval round filter with an oval cross section, a flat-oval round filter with an oval flanged cross section, a round conical filter, in which the round cross section narrows axially in the direction of the main axis, an oval-conical round filter, in which the oval cross section narrows axially at least in the direction of a transverse axis, a flat round conical flat-oval filter, in which the flat-oval cross section is narrowed in the axial direction, at least in the direction of a transverse axis, or a hollow filter with another cross section, especially angular, and/or another axial transverse path in the direction of the main axis.
    [0025] The filter may advantageously be closed circumferentially, having a star-shaped, especially zigzag shape, or it may be bent in a wavy shape. The filter may also be circumferentially closed in an unbent state.
    [0026] With respect to the filtering medium, it can be filter paper, filtering fleece or another filtering medium suitable for air filtration. The filter medium can be provided in one layer or in several layers.
    [0027] Advantageously, the filter can have a support body, especially a support tube. The support body can advantageously be located in the inner element compartment. A support body which surrounds the filter in radially external position can also be provided. A circumferential wall of the support body can advantageously be permeable to air. The circumferential wall can advantageously be configured as a skeleton or grid. Advantageously, the support body can consist of plastic. Advantageously, the filter can rest on the support body. The support body can advantageously have at least one reinforcing rib which extends in the inner part of the support body in an axial direction. With a reinforcing rib of this type, unwanted compression or bending of the filter can be avoided. For example, with an oval cross-section filter, the reinforcing rib extends along the small half-shaft. Advantageously, other reinforcement ribs which project parallel to this half-shaft can be provided.
    [0028] Advantageously, the air filter may form part of an air intake section of a combustion engine. It can serve for the purification of combustion air, which is fed to a combustion engine. The invention is not, however, restricted to an air filter of an air intake section of a combustion engine of a motor vehicle, especially of a utility vehicle, i.e. a truck. On the contrary, it can also be used in other motor vehicle air systems. With regard to the air filter, it can also advantageously be an internal compartment filter. The air filter can also be used outside the scope of automotive technology, especially with industrial engines. Advantageously, the air filter may form part of an air intake system of a utility vehicle, especially a truck, a bus, a construction machine or an agricultural machine. The air intake system can advantageously be located on a vertical wall, especially a rear section, of a driver's cabin of a utility vehicle.
    [0029] In an advantageous embodiment, at least one support segment can have at least one lateral support counterface which can have at least one cylindrical segment and/or at least one segment of a cross section changeable in the direction of a main axis, especially the conical segment and whose main axis may extend axially or parallel to a housing axis which, in the case of the assembled filter, may be coaxial to the element axis. In this way, at least one lateral bearing counterface and at least one lateral bearing face can have the same orientation in the case of the assembled filter.
    [0030] Advantageously, with the filter mounted, the main axes of at least one lateral support face and at least one lateral support counterface can extend in a coaxial direction. In this way, at least one lateral support face can simply be applied over or snapped onto at least one lateral support face. With the filter mounted, advantageously the main axes of at least one side face supporting the at least one side supporting side face can extend parallel to the direction of mounting the filter with respect to the housing of the filter, especially in relation to the housing section that has at least one support segment. In this way, at least one lateral bearing face and at least one lateral bearing counterface can simply automatically, when mounting the filter, be inserted into the filter housing, especially when mounting the filter housing. filtering, starting to establish a correlation. Advantageously, in this way, when mounting the housing cover on a top of the housing, at least one lateral bearing face may be brought into relationship with at least one lateral bearing counterface.
    [0031] Advantageously, at least one supporting side counterface - at least in segments - can be complementary at least with respect to one supporting side face. In this way, a lateral support face can be abutted almost free of play on at least one lateral support face. In this way, a reliable and stabilized support in the transverse direction, especially radially or tangentially, towards the element axis can be verified in a simple way.
    [0032] Advantageously, at least one supporting side counterface can be straight-cylindrical and/or straight-conical. At least one supporting lateral counterface can at least also, in segments, be oblique-cylindrical and/or oblique-conical.
    [0033] At least one supporting side counterface can advantageously limit an oval, flat-oval or round cross section. It can also limit another different cross section, especially angular.
    [0034] At least one supporting side counterface may be circumferentially closed. But it can also present interruptions.
    [0035] At least one bearing segment may also have more than one bearing side counterface, preferably two bearing side counterfaces.
    [0036] Advantageously, at least one bearing segment may have a front groove, in particular a counter-bearing groove that extends circumferentially with respect to the main axis. Advantageously, the groove can be provided on a front side of at least one support segment, facing towards the filter. A radially inner bearing side counterface can be configured as the radially inner circumferential side of the groove with respect to the main axis of at least one bearing segment. Alternatively, or in addition, the outer radial bearing side counterface may be configured as the outer radial circumferential side of the groove.
    [0037] Alternatively or advantageously, at least one support segment may have a hollow cylindrical segment or a sleeve-shaped segment. A radially inner bearing side counterface may be configured as the radially inner circumferential face of the hollow or sleeve-shaped cylindrical segment with respect to the main axis of at least one bearing segment. Alternatively or additionally, an external radial bearing lateral counterface can be configured on the external radial circumferential side of the hollow cylindrical segment or in the form of a sleeve.
    [0038] In another advantageous modality, at least one lateral support face - with respect to its main axis - may be projected radially inwards, involving a hollow space of at least one support element, which may be open at the free end corresponding to at least one support element, and at least one side support counterface - with respect to its main axis - may face radially outwards and with the filter correctly mounted, the support side counterface may be fitted in the hollow housing of at least one support element.
    [0039] Advantageously, at least one support segment can be a kind of column or dome that encompasses said segment or can form part of it. At the free end of the column or dome, at least one supporting side counterface can be provided. With the other end, the column or dome may be joined with the filter housing, especially the housing cover. It can be joined with the filter housing, preferably in one piece.
    [0040] The column or dome can advantageously extend over a segment of the space of the filter housing. In this way, the filter may be supported at a closed distance at a bridged distance by the column or dome with respect to a corresponding wall of the filter housing. Advantageously, the space segment may be traversed by air during operation of the air filter. Depending on the direction of air flow inside the filter housing, with respect to the space segment, it can be an input space segment or an output space segment.
    [0041] Alternatively, at least one or another supporting lateral counterface may be turned radially inwards relative to its main axis. The support side counterface may comprise a hollow housing of at least one support segment which is open to at least one support segment provided at the respective free end. At least one or one additional lateral support face, with respect to its main axis, may face radially outwards. With the filter of correct construction, at least one side support face can be fitted into the hollow compartment of at least one support segment.
    [0042] In another advantageous mode, a support element may be arranged in a centralized position, with respect to the element axis, on one of the front faces of the filter. In this way, the filter can be supported in a central position. In this way, even with only a single support element and with only a single corresponding support segment, uniform support of the filter in the filter housing can be verified. Thus, the support can be accomplished with space, with reduced space needed for the modules needed for this purpose inside the filter housing.
    [0043] Advantageously, several support elements of another configuration can be additionally provided in the filter with corresponding support segments in the housing. Advantageously, the corresponding support elements, with respect to the element axis, can be positioned circumferentially on the front side where at least one support element is located. The additional support elements can advantageously be integrated in a marginal area of the front face. Advantageously, the additional support elements can support the filter, i.e. the element axis, in radial direction against corresponding additional support segments of the filter housing.
    [0044] With additional support elements it can be advantageously fillets. The additional support elements can advantageously be elastic. Furthermore, they can contribute to tolerance compensation and/or vibration dampening.
    [0045] In another advantageous modality, a support segment, with respect to a housing axis, which coincides - with the assembled filter - with the element axis, may be positioned in the central direction. This support element could simply cooperate with a corresponding support element in a central position.
    [0046] In another advantageous mode provided, several support elements may be arranged on one of the front faces of the filter. In this way, support can be further enhanced. In this way, a toppling of the filter with respect to the element axis can be avoided.
    [0047] Advantageously, two supporting elements can be arranged on one of the front faces of the filter, possibly on opposite sides of the element axis. Therefore, on opposite sides of the element axis, there can be uniform support of the filter.
    [0048] Advantageously, the support elements can be integrated in circumferential marginal areas of the front side. In this way, the lever relationships can be improved by the corresponding distance to the element axis. Therefore, vibrations and even mechanical loads can be introduced into the filter. The mechanical load on the filter can thus be reduced altogether.
    [0049] In another advantageous mode, support segments may be provided in the filter housing. Advantageously, support segments can be allocated to corresponding support elements in the filter element.
    [0050] Advantageously, two support elements can be provided on approximately opposite sides of an axis of the housing which coincides with the axis of the element with the filter in mounted position. But they can be provided, in a distributed way, for more than two support elements, being distributed evenly or unevenly.
    [0051] In another advantageous mode, at least one support element and at least one support segment may be positioned on an impure air side of the filter. In another embodiment, the support element and support segment can be positioned on a fresh air side.
    [0052] Advantageously, it may be configured between the filter, in the area of the front face, with at least one support element and an inner wall of a filter housing that surrounds the filter in radially external position, a slit may be configured. Through this slit, air can enter or exit the surrounding space in radially external position or filter. Therefore, an air stream may flow axially towards the element axis from a segment of an inlet space of the filter housing to the inflow side of the filter medium. According to the direction of flow, the inflow side of the filter medium may be in the inner element compartment or in the outer radial circumferential side of the filter element. Correspondingly, the air stream may flow axially with respect to the element axis from the filter-flow side to a corresponding segment of a filter-flow compartment. By the axial air stream, an improved compaction of the filter housing and therefore less space required can be realized. Furthermore, in an axial airflow towards the inflow side, towards the inflow and/or the outflow side, a pressure difference between the inflow side and the outflow side can be reduced. Thus, for example, a lower pressure difference can be obtained than in a comparable air filter, in which the air stream is supplied tangentially to the inflow side of the filter, or is derived from the outflow side.
    [0053] In another advantageous mode, at least one support element may be arranged or profiled in an end body, especially an end plate of the filter. The support element can be integrated in the end body or it can be configured separately, being joined to said end body.
    [0054] Advantageously, the end body, especially the end plate, may be facing at least with a supporting element towards a segment of the inlet space of the filter housing for air to be purified. The input space segment can advantageously be joined with at least one input. In this way, at least one support element can be located on the impure air side of the filter.
    [0055] At least with a terminal body, the filter can be stabilized. Furthermore, with at least one end body, the filter can be sealed on the front face.
    [0056] At least one end body can advantageously consist of plastic. Advantageously, it may be glued, welded or otherwise sealed together with the front side of the filter. The material of which the end body consists can, advantageously, also be foamed or integrated with foam on the front face of the filter.
    [0057] At least one support element can advantageously be fixedly joined with at least one end body. At least one support element, as a separate module, can be specially glued, welded or foamed with the end body or can be fixedly joined to it in another way. At least one support element can also be mechanically joined with the end body through a groove connection, snap-on connection or otherwise. At least one support element may be detachably or inseparably joined with the end body.
    [0058] In another advantageous mode, on the front face of the filter, opposite at least one support element, between the filter and the filter housing, a seal may be integrated. With this seal, the filter can be sealed in axial and/or radial direction against the filter housing.
    [0059] In addition, the seal may have a supporting function. Advantageously, through the seal, the filter can support in an axial and/or radial direction against the filter housing. The seal can serve as a counter-support for at least one supporting element, in an axial direction. The filter element can in this way be mounted between the seal and at least one support element.
    [0060] Advantageously, the seal may consist of an elastic material, especially polyurethane, especially a polyurethane foam.
    [0061] The seal can advantageously cooperate with a corresponding sealing face on the side of the housing. The housing side sealing face can advantageously be arranged on a top of the filter housing.
    [0062] In another advantageous modality, an input space segment on the input side, an element space segment, within which the filter is integrated, as well as an output space segment on the output side, may be arranged, of the filter housing, being positioned in a linear direction and along the air flow path through the air filter, in sequential position. In this way, an axial air inflow to the inflow side of the filter can be easily configured. In addition, in this way, an axial flow of filtered air from the clean air of the filter can be achieved. Any pressure differences between the clean air side or the impure air side can be reduced in this way. Advantageously, a main flow direction of air from the inlet space segment can project through the element space segment to the exit space segment essentially in an axial direction, facing in the direction of the element axis.
    [0063] In another advantageous mode of the air filter, at least one support segment has at least one transfixing opening which is provided in such a way that through the opening a segment of the filter can be seen from the outside of the filter housing . In particular, through the opening, a segment of the support element and/or the front face, i.e. of an end body of the filter, can be seen. Regarding the opening, it is, for example, a perforation. It can be recognized by the opening if a filter is mounted inside the filter housing, so the opening functions as a mounting control. In order to avoid an exchange of air with the inner compartment through the opening, the support segment in the housing and the support element in the filter are preferably configured in such a way that the opening is sealed. For example, across the supporting side face and the supporting side counterface, a seal is provided. Preferably, the opening is aligned in the axial direction of the housing.
    [0064] In addition, the technical task will be so selected with respect to the filter, that the filter presents on an outer side, away from the inner element compartment on at least one axial front face relative to the axis of element, at least one bearing element comprising a lateral bearing face, which, at least in segments, is cylindrical or having a cross-section changeable in the direction of a main axis of the lateral bearing face, which main axis extends in parallel or coaxially to the element axis and with which at least one support element abuts at least against a corresponding support segment on the side of the air filter housing, where the filter, being able to support at least transversely to the element axis.
    [0065] The above-mentioned advantages and characteristics in connection with the air filter according to the invention and its advantageous embodiments are valid for the filter according to the invention and its correspondingly advantageous embodiments. Especially advantageous filter modalities are indicated in the embodiments.
    [0066] Advantageously, the support element is configured in such a way that it is suitable for an axial support of the filter inside the filter housing. Preferably, the support element advances in the axial direction at least 15 mm from the axial front face of the filter.
    [0067] The filter may be a hollow filter, so that the filter medium comprises an internal element compartment relative to the element axis. The through-flow takes place in a filter of this type in a radial direction, preferably from the outside towards the inside. Alternatively, the filter means can also consist of alternately closed channels, the filter means being so rolled up or stacked that a compact filter element is formed. A filter element of this type is flow through in an axial direction.
    [0068] According to one embodiment, the lateral support face is configured closed in the circumferential direction. In an alternative configuration, the support side face is made up of several partial segments, at least two, mutually separated. For example, slots are formed in a circumferentially closed bearing side face so that separate partial segments result. The different sub-segments can, however, also be configured individually on the front side of the filter.
    [0069] According to an advantageous method of the filter, at least one circumference of the axial front face with the support element, there may be provided at least two support cams, by means of which the filter can be supported in the filter housing transversely to the element axis. Preferably, the support cams extend in the direction of the element axis and in the direction transverse to the element axis, beyond the axial transverse face of the filter. Advantageously, going beyond the axial front face of the filter. Advantageously, the support cams are positioned opposite each other. For example, the support cams are profiled on a filter end plate. The support cams preferably consist of PUR or another material which is sufficiently rigid but still flexible.
    [0070] According to an advantageous modality, the filter has a cross section that diverges from a round circular shape, especially presenting an oval or flat-oval cross section. The filter can be cylindrical. However, another conical shape is also possible, with the cross section narrowing towards the axial front face that presents the support element. Especially in a hollow element, which is radially traversed by the flow, the conical shape enables an improved inflow of the filter face.
    [0071] In the filter housing according to the invention, furthermore, the technical task will be solved by the fact that, on the side of the filter housing, at least one support segment is provided which covers a lateral support counterface , whose main axis extends parallel or coaxial to an axis of the housing and which, with the filter mounted, extends axially to the element axis and which, at least in segments, is cylindrical or with a cross section that can be changed in the direction of the main axis and against which a corresponding support element located on an outer face, spaced apart from the inner element compartment, in at least transverse to the housing axis and which lies on an axial front face of the filter element at least with respect to the element axis.
    [0072] The advantages and characteristics mentioned in connection with the air filter according to the invention and the filter element according to the invention, as well as their advantageous modalities, are valid for the filter housing according to the invention and their corresponding advantageous embodiments.

    [0087] Figure 1 shows an air filter 10 of an air suction section of a combustion engine of a utility vehicle, according to a first example of execution, in a longitudinal section. The air filter 10 is integrated into an air intake section of the combustion engine. It serves to purify the combustion air that is fed to the combustion engine for the purpose of combustion.
    [0088] The air filter 10 comprises a filter housing 12 which can be opened. The filter housing 12 is of flat-oval construction. With respect to its reduced transverse axis, the filter housing 12 is flat with respect to an oval filter housing of approximately elliptical cross section, in the direction of its reduced transverse axis. In Figure 1, the section is shown along an extended transverse axis of the filter housing 12. The filter housing 12 has a housing top 14, in Figure 1 on the left, and has a housing cap 20, in the figure. 1 on the right side. The top of the housing 14 has a mounting opening 16, in figure 1 on the right side, for mounting a filter 18. The mounting opening 16 is closed with the housing cover 20.
    [0089] The top of the housing 14 has an outlet 22 for the air which flows into a spatial segment of the outlet 24 from the top of the housing 14. On the outside of the filter housing 12, the outlet 22 - through air lines not shown - is linked with the combustion engine.
    [0090] The housing cover 20 has an inlet 26 for the air to be filtered, which flows into an inlet space segment 29 of the housing cover 20 and on the outside of the filter housing 12, is joined with the environment.
    [0091] The filter 18 is such integrated in an element space segment 30 from the top of the housing 14 and separates the input 26 from the output 22. The element space segment 30 is found in a linear arrangement between the input space segment 28 and the output space segment 24.
    [0092] The input space segment 28, the element space segment 30, as well as the output space segment 24, are sequentially positioned in axial direction, constituting an axis 32. The axis 32 coincides with an axis of the filter housing 12 In the present example of embodiment, the shaft 32 also coincides with an assembly direction, in which the filter 18 is fitted to the top of the housing 14 and can be removed from it. In the present exemplary embodiment, the shaft 32 also coincides with an assembly direction, in which the housing cover 20 is mounted on the housing cover 14. The assembly opening 16 circumferentially surrounds the shaft 32.
    [0093] When the expressions "axial", "radial", "circumferentially" or "coaxial" are then used, these expressions refer - unless otherwise indicated, to axis 32.
    [0094] Axially between the element space segment 30 and the output space segment 24, the top of the housing 14 has a closed circumferential sealing face 34. The sealing face 34 extends in a radial direction. The sealing face 34 is mounted towards the housing cover 20. On the sealing face 34, a seal 36 of the filter 18, circumferentially closed, is densely abutted.
    [0095] The radially inner cross section of the space segment of element 30 is greater than an outer radial cross section of the sealing face 34.
    [0096] Between an outer radial circumferential face of the filter 18 and the inner radial circumferential face of the element space segment 30, an annular inflow compartment 38 is configured. The inflow annular compartment 38, by means of a seal 36, is separated from the output space segment 24.
    [0097] On the side facing towards the housing cover 20, the annular inflow compartment 38 - through a circumferential slot 40 - is joined with the inlet space segment 28. The inlet space segment 28 and the inflow annular segment 38 meet yourself on the impure air side of the filter 18.
    [0098] The input space segment 28 exceeds the filter 18 and slit 40 in radial direction and overlaps the slit 40. The input space segment 28 has its maximum axial extension in an area, in which the input 26 is foreseen. The maximum axial extent of input space segment 28 is approximately as large as the axial extent of element space segment 30.
    [0099] The output space segment 24 has its maximum axial extension in an area, in which the output 22 is arranged. The maximum axial extension of the output special segment 24 is a little smaller than the maximum axial extension of the space segment of entry 28 and the axial extent of the element space segment 30.
    [00100] On the housing cover 20, a support column 42 is mounted. This column is integrally joined with the housing cover 20. The support column 42 extends approximately coaxial with the axis 32, i.e. coaxial towards the housing shaft. It is arranged centrally with respect to the housing axis. The support column 42 extends in the inner space segment 289 from an inner side of the housing cover 20, facing the direction of the filter 18, towards a front face of the inlet side of the filter 18. The support column 42 is located on the impure air side of filter 46.
    [00101] On the free front face of the support column 42, facing the direction of the filter 18, a coaxial counter-support groove is provided, extending circumferentially, in the direction of a main axis of the support column 42, i.e. , in the direction of the axis 32, and the axis of the housing. The backrest groove is a hollow space of the support post 42 which is open towards the free front face of the support post 42. A radially inner circumferential wall of the backrest groove forms a radially inner support counterface 44. The inner radial bearing counterface 44 faces radially outwardly with respect to the main axis of the bearing column 42. A radially outer circumferential wall of the mating groove forms an outer radial bearing counterface 45. The bearing counterface The outer radial 45 faces radially inwards relative to the main axis of the support column 42. The lateral support counterfaces 44 and 45 are coaxial with the axis 32. They have a cylindrical design. Furthermore, they have an oval cross section. The oblong transverse axis of the respective oval section is located in the drawn plane of figure 1, and the short transverse axis lies perpendicularly in the drawn plane.
    [00102] Filter 18 is being shown in figures 2 through 5 in differentiated detailed views. With respect to filter 18, it is a flat-oval, conical round filter. Filter 18 is in coaxial position to an element axis. With the filter 18 assembled, in the example shown, the element axis coincides with the axis of the housing, that is, with the axis 32. The filter 18 has a flat-oval cross section. The long transverse axis of the oval section is in the drawn plane of figure 1, the short transverse axis is perpendicular to the drawn plane. In the direction of the short transverse axis, the filter 18 is, moreover, flat, which is why the designation "flat-oval". In a different, relative sense, the expression "oval" designates an approximately elliptical cross section. The radially outer circumferential face and a radially inner circumferential face of the filter 18 have a tapered path. The outer cross section and the inner cross section of the filter 18 narrow from its output side front side, facing towards the output space segment 24, towards the input side front side.
    [00103] The filter 18 comprises a filtering means 46, bent in a zigzag shape with respect to an element axis, circumferentially closed. With respect to filtering medium 46, it is a filtering paper which is suitable for filtering air. However, it can also be another suitable filtering means for filtering, for example, filter fleece. The filtering means 46 may be provided in one layer or in several layers.
    [00104] On its front face on the output side, the filtering means 46 is joined with a coaxial end plate 48 on the output side. This output side endplate 48 consists of an elastomer. It is sealingly glued to the front face of the filtering means 46. It may also be joined in another way with the filtering means 46. For example, it may also be welded together or consist of surface-applied foam or integrated foam. The radially outer circumferential face of the output side endplate 48 abuts with minimal clearance the radially inner face of the top of the housing 14.
    [00105] The end plate 48 on the outlet side has a second central outflow opening 50. The outflow opening 50 extends over the overall radial inner cross section of the filtering means 46. Through the outflow opening 50, a inner element compartment 58 of filter 18, surrounded by filter means 46, is joined with output space segment 24.
    [00106] On the outer side of the end plate 48 on the outlet side, axially opposite to the filtering means 46, is the seal 36. The seal 36 consists of an elastic polyurethane foam. It is fitted to the terminal board 48 on the output side. Instead of polyurethane foam, the seal 36 may consist of another material, preferably elastic, for example a plastic. Instead of being applied in the form of a foam, it could also be joined in another way with the end plate 48 on the outlet side. Seal 36 is coaxially with the element axis and circumferentially surrounds the outflow opening 50. It extends in an axial direction, bears axially on the sealing face 34 of the top of the housing 14.
    [00107] On the inlet side front face, the filtering means 46 is sealingly joined with an inlet side end plate 54. The input side end plate 54 closes the inner element compartment 52 towards the input space segment 28. The input side end plate 54 - similarly as the output side end plate 48 - is joined in shape. sealed with the filtering means 46. It may also be connected in another way with the filtering means 46.
    [00108] Between the end plate 54 on the inlet side and the end plate 48 on the outlet side, a coaxial support tube 56 extends in the inner element compartment 52. The support tube 56 consists of plastic. It is built similar to a grid. Its circumferential face is permeable to air. The support tube 56 has a flat-oval, conical shape, corresponding to the filter means 46. The inner radial circumferential side of the filter means 46 rests on the outer radial circumferential face of the support tube 56. recognize that the support tube 56 has a reinforcing rib which extends along the short transverse axis between the oblong sides of the flat-oval filter element 18. The reinforcement opening does not extend throughout the inner element compartment 52, however, it presents a recess towards the opening of the filter element 18, so that an exchange of air can take place between the two chambers of the filter 18, formed by the reinforcing rib.
    [00109] On the axial outer side of the inlet side end plate 54, remote from the inner element compartment 52, there is a support element 58. This support element 58 is located on the impure air side of the middle filter 46. The support member 58 is firmly joined with the end plate 54 on the inlet side. The support element 58 is produced from an elastic material. For example, it could consist of a polyurethane foam. The support element 58 is applied in the form of a foam to the end plate 54 on the inlet side. But it could also be joined in another way with the end plate 54 on the input side. It can also be used with a support element that is integrally joined with the end plate 54 on the inlet side.
    [00110] The support element 58 has a glove shape. It is shaped like a hollow cylinder whose main axis - in the example execution shown - extends coaxially in the direction of the element axis. The support element 58 has an approximately oval cross-section. Its short transverse axis - in figure 1 - lies in the drawn plane, while its long transverse axis lies perpendicularly in the drawn plane. The orientation of the support element 58 with respect to the axis 32, i.e. the axis of the housing, corresponds to the orientation of the counter-support side faces 44 and 45.
    [00111] The radially inner circumferential face of the bearing element 58 forms a radially inner bearing side face 60. The radially inner bearing side face 60 surrounds a hollow housing 62 of the bearing element 58. A main axis of the radially inner bearing side face 60 - in the example of embodiment shown - is coaxially with the main axis of the bearing element. support 58 and therefore also with respect to the element axis. The inner radial bearing side 60, with respect to its main axis, faces radially inwards. The inner cross section of the radially inner bearing side face 60 corresponds to the outer cross section of the radial inner bearing side counterface 44.
    [00112] The radially outer circumferential side of the bearing element 58 forms a radially outer bearing side face 61. The main axis of the outer radial bearing side face 61 extends coaxially with the main axis of the radially inner bearing side face 60. The outer radial bearing side face 61, with respect to its main axis, is mounted radially outwards. The outer cross section of the outer radial bearing side face 61 corresponds to the inner cross section of the outer radial bearing side face 45.
    [00113] The segment of the support column 42, surrounded by the counter-support groove and which supports the lateral support counterface 44 radially inside, with the filter 18 correctly assembled, is fitted in the hollow compartment 62 of the support element 58. A hollow, sleeve-like cylindrical bearing element 58 is fitted into the counter-groove of the bearing column 42. The inner radial bearing side face 60 is abutted to the inner radial bearing side counterface 44. The outer radial bearing side face 61 abuts on the outer radial support side counterface 45.
    [00114] On its side facing the end plate 54, the inner radial support side face 60 and the outer radial support side face 61 of the support element 58 have an oval cylindrical cross section. On its free side, remote from the end plate 54, the inner radial bearing side face 60 has a conical segment whose inner cross section widens outwards towards a free end of the bearing element 58. The outer cross section of the outer radial bearing side face 61 decreases, within the tapered segment, towards the free end of the bearing element 58. As a whole, the wall thickness of the bearing element 58 in the tapered segment towards the free edge decreases. Therefore, the engagement of the bearing element 58 in the counter-bearing groove of the bearing column 42 could be simplified.
    [00115] As a support element 58, the filter 18 will be supported through the support column 42 against the filter housing 12. This support takes place in the radial direction, that is, transverse to the element axis and the axis of the housing side and axial direction. By the combined action of the support element 58 with the support column 42, a filter 18 will be retained and positioned, radially and axially, on the inlet side, that is, on the impure air side. In this way, the filter 18 can be held in the filter housing 42, on the side facing the inlet space segment 28, without the slit 40 being covered by the necessary retaining components.
    [00116] Furthermore, on the outer radial edges of the end plate 54 on the inlet side, in the area of short transverse sides, two support cams 68 are provided. The support cams 68 overlap on the terminal plate 54 on the inlet side , both in radial and axial direction. The support cams 68 rest on corresponding support points, not shown in the figures, on the inner side of the housing cover 20, in radial direction.
    [00117] In the operation of the air filter 10, the air to be filtered passes through the inlet 26, which is indicated by an arrow 64, entering the inner space segment of the inlet 28. From that point, the air passes essentially towards axial through the slit 40, in the inflow compartment 38 towards the inflow side of the filter medium 46. The air passes through the filter medium 46 from the radially outer part to the radially inner part, being purified. The purified air passes through the circumferential side of the support tube 56 and reaches the inner element compartment 52. The purified air presents the inner element compartment 52 essentially in an axial direction, reaching the outlet space segment 24. From that point, the filtered air leaves filter housing 12 via outlet 22, indicated by arrow 66.
    [00118] For maintenance purposes, for example, for cleaning or replacement of filter 18, filter housing 12 may be opened. To do this, the housing cover 20 will be removed in an axial direction from the housing cover 14. In this procedure, the support element 52 will automatically be removed from the counter-support groove at the end of the support column 42. The filter 18 will be extracted at axial direction of the elemental space segment 30 from the top of the housing 14. It can be replaced by a new filter 18 or it can be reassembled after cleaning.
    [00119] For assembly, a filter 18 will be inserted to such an extent with the end plate 48 on the outlet side and, towards the front, in the axial direction, into the top of the housing 14 until the seal 36 is abutted on the face seal 34. Then the housing cover 20 will be inserted with its side open, with the front in axial direction over the mounting opening 16 of the top of the housing 14. In this procedure, the support member 58 is fitted into the groove of Support column counter-support 42. The segment with the inner radial support side counterface 44, at the end of the support column 42, penetrates into the hollow housing 62 of the support element 58.
    [00120] Figure 6 presents a second example of execution of an air filter 110. Those elements that, in relation to the first example of execution of figures 1 to 5, are similar, have the same reference numbers with the addition of 100 The second example of execution differs from the first example of execution in that in the second example of execution, the filter 118 has on its end plate 154 on the input side two supporting elements 158. The filter 118 is shown in the figures of 7 to 10 in different perspectives and in a detailed way.
    [00121] The support elements 158 have the shape of sleeves in a circular cylindrical shape. They lie in the area of a side edge on the transverse face of the inlet side endplate 154. The hollow compartments 162 of the bearing elements 158, with respect to a respective main axis of the bearing element 158, are surrounded by an inner radial bearing side face 160. The inner radial bearing side faces 160, with respect to the main axis, they face radially inwards. In a tapered segment on the free front face, the hollow compartments 162 widen towards the free end of the bearing elements 158. The circumferential radial outer sides of the bearing elements 158 form an outer radial bearing lateral face 161.
    [00122] Furthermore, different from the first example of execution, in the second example of execution, two support columns 142 are provided for the support elements 158. The support columns 142 extend with their main axis in parallel to the axis 132, i.e. parallel to the axis of the filter housing 112.
    [00123] In a manner analogous to the first example of execution, the sleeve-like support elements 158 are fitted in a counter-support groove in the free front faces of the support columns 142. In this case, the segments that support the support counterfaces Inner radial sides 144 are fitted to the free ends of the support columns 142 in corresponding hollow compartments 162 of the bearing elements 158. The outer radial bearing side counterfaces 145 of the bearing columns 142 surround the outer radial bearing side faces 161 of the bearing elements. support 158. Support elements 158 - with respect to their main axes, support each other in radial direction. With respect to axis 132, in the example of embodiment shown, that is, on the element axis and housing axis, support elements 158 are supported in the axial direction. According to the circumferential side of the support element 158, each support element 158 is supported in a radial or tangential direction or in another direction, transversely to the axis 132. A rotation about the axis 132 of the filter 118 in the area of the end plate 158 on the inlet side, in the present case, therefore, the housing axis can thus be avoided.
    [00124] Different from what happens in relation to the first example of execution, the filter 118 is of cylindrical constitution. In this case, it is a flat-oval round filter with a cylindrical constitution.
    [00125] Furthermore, in the second embodiment, the support cams 68 of the first embodiment are dispensed with.
    [00126] Figures 11 and 12 show a third mode of an air filter 210. The elements corresponding to the elements of the first example of execution have the same reference numbers added by 200. The air filter 210 may be mounted in a horizontal direction and, as illustrated, it can be passed through by the air flow from the right side to the left side or it can be mounted perpendicularly, being traversed from the top to the bottom.
    [00127] The housing cover 220 has two inlets 226 for the air to be filtered and an opposite outlet 222. The two inputs 226 are symmetrically positioned with respect to axis 232. In other configurations, element space segment 230 is in a linear arrangement between inner space segment 228 and outer space segment 224.
    [00128] Filter 218 is cylindrical and has an oval-eccentric basic face that is specular-symmetric with respect to a transverse axis. Three support elements 258 are profiled on the inlet side end plate 254. The inlet side end plate 258 is formed in the form of elastic polyurethane segments and is applied by foam to the filter medium. At the center, the end plate is formed by a plastic component that forms part of the support tube 256 of the filter 218. The support members 258 are configured integrally with the elastic segment of the end plate 254.
    [00129] The support elements 258 have a circular cylindrical cross section and define a hollow compartment 262 which is surrounded by an inner support side face 260, which, relative to a main axis of the support element 258, faces towards radial inwards. Analogous to the second example of execution, the cylindrical segment ends up in a conical segment. In this way, the hollow compartments 262 on the free front side are widened towards the free end of the bearing elements 258. The circumferential radial outer faces of the bearing elements 258 form outer radial bearing lateral faces 261.
    [00130] With respect to each of the three support elements 258, the housing 212 has a support column 242. The support columns 242 extend with their main axis in parallel to the axis 232 and, therefore, in parallel to with the axis of the filter housing 212. Analogous to the previous examples of execution, the support elements 258 are fitted in each counter-support groove on the free front sides of the support columns 242. The radial inner side support sides 268 of the elements struts 258 are abutted to a corresponding inner radial bearing side counterface 244 of the support columns 242, and the outer radial lateral bearing faces 261 are abutted to corresponding bearing lateral counterfaces 245. The bearing elements 258 bear - with respect to its main axis - in radial direction. With respect to the axis 232, which coincides with a housing axis and an element axis, the supporting elements 258 bear at least in a transverse direction, for example in a radial or tangential direction. Furthermore, through the support elements 258 there is an axial support in the direction of the axis 232.
    [00131] Through the three support elements 258, the filter 218 is mounted in a stabilized manner in a transverse direction to and along the axis 232 within the housing 212. The arrangement of the support elements 258 and the support columns 242 make it possible the optimized inflow of filter 218, because the cross section of annular slit 240, which interconnects input space segment 228 with element space segment 230, will not be reduced by this action.
