Embodiment Construction

[0042] figure 1 and figure 2 The filter device 1 is shown in a perspective view, wherein the housing 2 of the filter device 1 is shown in figure 1 , while the filter insert 3 of the filter device 1 is shown in figure 2 middle.

[0043] according to figure 1 , the housing 2 comprises a second housing part 4 which is realized in a cup-shaped manner in the example shown. For the sake of brevity and without limiting the possible three-dimensional arrangements, the second housing part 4 will be referred to as the lower housing part 4 . Arranged at the side of the lower housing part 4 is a fluid connection 5 which allows the fluid to be filtered by the filter device 1 to flow through the chamber 16 of the filter device for filtering purposes. The connection piece 5 can be used, for example, as an inlet 6 for fluid to enter the filter device 1 . Along its edge, the lower housing part 4 has a second housing structure 8 , which extends in the circumferential direction 7 and whi...

Abstract

The invention relates to a filter device (1) comprising a housing (2) in which a filter insert (3) is arranged. The filter insert (3) has a seal (19) which is pressed against housing structures (8, 26) of the housing (2) in order to seal a clean side (27) from an unfiltered side (28) of the filter device (1). The use of unsuitable filter inserts (3) in the housing (2) is prevented or at least reduced in that the housing (2) is provided with a contour (13) which has a recess (14) while the filter insert (3) is provided with a support element (24) that interacts with the contour (13) such that the seal (19) is pressed against the housing (2) on the side facing away from the support element (24) via the support element (24) for sealing purposes. The invention further relates to such a filterinsert (3).

Description

technical field [0001] According to the preamble of claim 1 , the invention relates to a filter device comprising a filter insert. The invention also relates to such a filter insert. Background technique [0002] With the help of a filter device, fluids, such as liquids or gases, can be filtered. In the context of filtration, the corresponding fluid is released, for example, from dust particles and / or unwanted components are separated from the fluid. Common filter devices thus have a two-part housing, in which a corresponding filter insert is arranged for filtering the fluid and through which the fluid to be filtered flows. In order to seal the unfiltered side of the filter device (in which the fluid to be filtered flows into the filter device) from the clean side (in which the filtered fluid flows into), such a filter inserts The element basically has a seal which extends in the circumferential direction on the edge side of the filter insert. The seal thus interacts wit...
