Embodiment Construction

[0044] exist figure 1 , a side view of a filter device 1 for filtering a fluid, for example fresh air for an internal combustion engine not shown, is shown. The filter device 1 has a filter housing 2 which is composed of two parts and has a lower housing part 2' and an upper housing part 2". The housing parts 2', 2" are mounted against each other by pivot bearings 3 so that the housing 2 can be turned off and on. A connection 4 is formed at each housing part 2 ′, 2 ″ in order to introduce fluid to be filtered into the filter device 1 or to convey filtered fluid out of the filter device 1 , respectively.

[0045] For filtering the fluid, the filter device 1 has a replaceable filter element 5, which is shown in figure 2 in top view and image 3 in side view. The filter element is formed in the form of a plate. This means that the filter element 5 is designed so as to be larger in the longitudinal direction 6 than in the vertical direction 7 extending transversely to the lo...

Abstract

The present invention relates to a flat filter element (5) having a filter body (9) made up of a folded filter material (10), said filter element having a side edge (12) running along its edge in the circumferential direction. A stable design and sealing of the filter element (5) are achieved by the side edge having at least one adhesive portion (14) extending along the side edge (12), and at least one strip portion (15) with a side strip (16), said strip portion extending along the side edge (12). The invention also relates to a filter device (1) having a filter housing (2) in which a filter element (5) of this type is arranged. The invention additionally relates to a filter housing (2) of this type.

Description

technical field [0001] The invention relates to a flat filter element for filtering fluids, to a filter device having a filter element of this type, and to a filter housing of a filter device of this type. Background technique [0002] For cleaning gases or liquids, respectively, filter devices are usually used which have filter elements for this purpose. In various applications, the use of flat filter elements is desired and / or required here. Such a filter element can have a filter body of pleated filter material. [0003] In order to seal the filter element or the filter body, respectively, it is conceivable to glue adjacent creases along the peripheral edge of the filter body in the region of the side edges and thereby achieve a corresponding sealing of the filter element. [0004] A disadvantage here is that the filter element or filter body, respectively, is thus relatively unstable. The filter element can thus be destroyed during installation in the associated filte...
