Abstract
A filter device may include a housing including a first housing part and a second housing part which define a chamber through which a fluid is flowable. The device may also include a filter insert arranged in the housing and configured to filter the fluid. The filter insert may include a seal. The second housing structure may be configured as a web. A circumferential section of the second housing structure may include a contour. The contour may include a recess configured as an interruption in an area of the web. The device may further include a support element arranged on the filter insert interacting with the second housing structure in an area of the contour. The second housing structure may press the first sealing surface against the first housing structure via the support element to seal a clean side from an unfiltered side.
Claims20
A filter device comprising:
- a housing including a first housing part and a second housing part which define a chamber of the housing through which a fluid is flowable;
- a filter insert arranged in the housing and configured to filter the fluid;
- the filter insert including a seal extending on an edge side of the filter insert in a circumferential direction configured to seal a clean side arranged downstream from the filter insert from an unfiltered side arranged upstream of the filter insert;
- the seal having a first sealing surface and a second sealing surface, the second sealing surface abutting a second housing structure of the second housing part, the first sealing surface facing away from the second sealing surface and abutting a first housing structure of the first housing part;
- the seal pressed by the first housing structure and the second housing structure to seal the clean side from the unfiltered side;
- the second housing structure configured as a web;
- a circumferential section of the second housing structure including a contour, the contour including a recess configured as an interruption in an area of the web;
- the second sealing surface abutting the web;
- and
- a support element arranged on the filter insert and interacting with the second housing structure in an area of the contour, wherein the second housing structure presses the first sealing surface against the first housing structure via the support element to seal the clean side from the unfiltered side.
A filter device comprising:
- a housing including a first housing part and a second housing part defining a chamber through which a fluid is flowable, the first housing part including a first housing structure, the second housing part including a second housing structure configured as a web, the second housing structure having a circumferential section including a contour defined by a recess, the recess configured as an interruption in an area of the web;
- a filter insert arranged in the housing and configured to filter the fluid;
- a seal extending on an edge side of the filter insert in a circumferential direction, the seal having a first sealing surface abutting the first housing structure and a second sealing surface abutting the web of the second housing structure, the first sealing surface and the second sealing surface facing away from one another;
- and
- a support element arranged on the filter insert offset relative to the second sealing surface, the support element sticking out from the filter insert and interacting with the second housing structure in an area of the contour, wherein the support element is engaged with the contour and fills the recess;
- wherein the first sealing surface is pressed against the first housing structure via the second housing structure and the support element sealing a clean side arranged downstream from the filter insert from an unfiltered side arranged upstream of the filter insert.
