Abstract:
A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.

A filter housing (11) has at least one inlet (15) and at least one outlet (17) for the fluid. The filter element (10) includes a filter body of a filter medium (18).The filter element (10) is configured to be arranged in a filter housing (11) separating the at least one inlet (15) from the at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) can be aligned parallel or axially to an installation direction (12) of the filter element into the filter housing. The filter element (10) may include at least one guide crosspiece (46, 48) which extends axially and radially outward on a peripheral exterior side (26), relative to the element axis (14), of the filter element (10). The filter element (10) has at least one seal (42) running peripherally relative to the element axis (14), the seal (42) having a seal line with at least one convexity (54) arranged peripherally between two corner regions of the filter element (10) and is separated by these corner regions.
Abstract:
A hollow filter element, including: a filter medium (64) for filtering the fluid, the filter medium circumferentially surrounding an element interior space (72) in relation to an element axis (32), forming a conical-oval round filter element; wherein the hollow filter element (18) includes: at least at one outer face facing away from the element interior space (72) at an end face (66); at least one support element (78) configured to support the hollow filter element (18) at a housing-sided support section (42) of a filter housing (12); and at least one fluid passage (81) arranged at the end face (66) in the center of the at least one support element (78), the at least one fluid passage connected to the element interior space (72) for connecting a secondary fluid line connector (45) of a housing-sided secondary fluid line (47) and/or for receiving a housing-sided positioning dome (245).
Abstract:
Being described are a filter (13) for fluid, particularly an air filter, particularly of an internal combustion engine, particularly of a motor vehicle, a filter housing (11) and at least one filter element (10). The filter housing (11) has at least one inlet (15) and at least one outlet (17) for the fluid. The filter element (10), particularly a flat filter element, comprises an open filter bellows (16) made of a filter medium (18), which has an upstream side (28) and a downstream side (30) for the fluid to be filtered. The filter element (10) is arranged in the filter housing (11) in such a manner that it separates the at least one inlet (15) from the at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) can be aligned parallel or axially to an installation direction (12) of the filter element for installing the filter element (10) into the filter housing. The filter element (10) has at least one guide crosspiece (46, 48), which extends axially and radially outward on a peripheral exterior side (26), relative to the element axis (14), of the filter element (10).In addition, the filter element (10) has at least one seal (42) running peripherally relative to the element axis (14), wherein the seal (42) has a seal line, which comprises at least one convexity (54), which is arranged peripherally between two corner regions of the filter element (10) and is separated by these corner regions.
Abstract:
A filter element (10) is provided with open filter bellows (16) of a filter medium (18). The filter element (10) has at least one longitudinal mating surface (40) which is directed with at least one direction component axially to an element axis (14) of the filter element (10) and which is in contact with a corresponding longitudinal mating surface of the filter housing (11) for securing the filter element (10) axially to the element axis (14). The filter element (10) has at least one transverse retaining surface (52) which is directed with at least one direction component across the element axis (14). The transverse retaining surface (52) is separated from the at least one longitudinal retaining surface (40) and may be in contact with a corresponding transverse mating surface (56) of the filter housing (11) for securing the filter element (10) across the element axis (14).
