过滤器装置的过滤器元件、过滤器壳体和过滤器装置
摘要：
描述了用于特别是机动车辆的特别是内燃机的过滤器装置（10）的过滤器元件（18）、过滤器壳体（12）和过滤器装置（10），用于流体，特别是空气、气体、燃料、油、水、尿素水溶液或类似物。过滤器元件（18）能可更换地布置在过滤器壳体（12）中在用于流体的至少一个入口（14）和至少一个出口（16）之间。过滤器元件（18）包括至少一个过滤器波纹管（54），其具有至少一个过滤器介质和至少一个密封件（28），密封件（28）相对于过滤器元件（18）的轴线（20）周向地布置在过滤器波纹管（54）的端部侧边缘（52）处。至少一个密封件（28）包括周向紧固区域（56）和周向密封件区域（62），周向紧固区域（56）具有从径向外部到径向内部延伸的径向紧固部段（58）和至少利用一方向分量平行于轴线（20）延伸的轴向紧固部段（60）。紧固区域（56）借助于径向紧固部段（58）和轴向紧固部段（60）围绕过滤器波纹管（54）的边缘（52）接合。径向紧固部段（58）的背离过滤器波纹管（54）的后侧形成用于壳体上的径向内部压力施加部段（48）的保持表面（59）。轴向紧固部段（60）的背离过滤器波纹管（54）的后侧在密封件区域（62）中形成至少部分周向的凹槽（64）的径向内部边界，用于接收壳体上的径向外部压力施加部段（32）。凹槽（64）在与轴向紧固部段（60）相对地定位的径向外部周向侧处从径向内部到径向外部观察由周向密封件凸起（66）界定，周向密封件凸起（66）在轴向方向上观察突出超过所述轴向紧固部段（60）。在所述密封件区域（62）的与所述凹槽（64）轴向相对地定位的外侧处布置至少在轴向方向上作用的周向密封表面（70），所述周向密封表面（70）比所述径向紧固部段（58）的所述保持表面（59）位于距所述过滤器波纹管（54）的端部侧（72）的更大的轴向间隔处。在所述凹槽（64）的基部和所述密封表面（70）之间的轴向间隔大于在所述凹槽（64）的所述基部到所述轴向密封部段（60）的过渡部和所述密封表面（59）到所述密封件区域（62）的过渡部之间的间隔。
摘要（英）：

A filter element (18) for a filter device (10) for fluid, in particular air, gas, fuel, oil, water, urea-water solution or the like, in particular of an internal combustion engine, in particular of amotor vehicle, and a filter housing (12) and a filter device (10) are described. The filter element (18) is arranged exchangeably in a filter housing (12) between at least one inlet (14) and at leastone outlet (16) for fluid. The filter element (18) has at least one filter bellows (54) with at least one filter medium and with at least one seal (28) which, with respect to an axis (20) of the filter element (18), is arranged circumferentially on a face-side edge (52) of the filter bellows (54). The at least one seal (28) has a circumferential fastening region (56), with a radial fastening section (58) which extends from radially outside to radially inside and with an axial fastening section (60) which extends at least with a direction component parallel to the axis (20), and a circumferential seal region (62). The fastening region (56) engages with the radial fastening section (58) and the axial fastening section (60) around the edge (52) of the filter bellows (54). A rear side, avertedfrom the filter bellows (54), of the radial fastening section (58) forms a holding surface (59) for a radially inner pressure-exerting section (48) on the housing. A rear side, averted from the filter bellows (54), of the axial fastening section (60) forms a radially inner delimitation of an at least partially circumferential groove (64) in the seal region (62) for receiving a radially outer pressure-exerting section (32) on the housing. The groove (64) is delimited, on the radially outer circumferential side, which is situated opposite the axial fastening section (60) as viewed from radiallyinside to radially outside, by a circumferential seal projection (66) which projects beyond the axial fastening section (60) as viewed in an axial direction. On the outer side, situated axially opposite the groove (64), of the seal region (62), there is arranged a circumferential seal surface (70) which acts at least in an axial direction and which is situated with a greater axial spacing to theface side (72) of the filter bellows (54) than the holding surface (59) of the radial fastening section (58). An axial spacing between a base of the groove (64) and the seal surface (70) is greater than a spacing between a transition of the base of the groove (64) to the axial fastening section (60) and a transition of the holding surface (59) to the seal region (62).
