摘要:
The invention relates to a filter, especially an air filter for the intake air of internal combustion engines. The filter has a housing consisting of two conical housing shells (12, 12a), wherein a support tube (17), especially a conical support tube, is integrated into one of the housing shells. A conical round filter cartridge having axial play compensation (21) is pushed into said tube. The housing shells (12, 12a) are joined by means of a central screwed connection (22), wherein sealing between the housing shells is ensured by a labyrinth seal (14, 15). The inventive filter is insensitive to an axial tolerance range of the individual components thereby minimizing production costs. Moreover, the housing shells are embodied in such a way that they can be produced using simple casting molds with no undercuttings which additionally enhances the economic viability of the filter. Undercuttings are prevented especially in the case of the grid-shaped support tube (17) due to the fact that its conical shape produces a radial distance (a) between the radial girders (29) of the support tube.

The invention describes a method for producing an in particular rectangular flat filter element (10) for fluids, in particular of a motor vehicle, and a flat filter element (10) in which a filter medium is folded so as to form a filter bellows (14). The filter bellows (14) is connected, in regions (22) of its end folds (16), in a fluid-tight manner to a fixed filter element frame (12) and the end edges (18) of the filter bellows (14) are connected in a fluid-tight manner to the filter element frame (12), in such a way that the filter bellows (14) is held in the filter element frame (12).

The invention relates to an air-filtration system for purifying an air stream, in particular the induction air of an internal combustion engine. The air-filtration system comprises a system plate (10), a pre-filtration side (13), a filter housing (12) comprising a filter element (16) and a post-filtration side (19). The filter element (16) hermetically seals and separates the pre-filtration side (13) from the post-filtration side (19). The pre-filtration side (13) is configured by a first half-shell (11), which is connected to the system plate (10) in a fixed, hermetic manner. The filter housing (12) is likewise connected to the system plate in a fixed manner. The sealed, fixed connection of the system plate (10) to the first half-shell (11) allows the air-filtration system to be produced in a simpler, more rapid and more cost-effective manner, obviating the need for seals and connecting elements, in addition to their assembly.
