Abstract: A flat filter element for filtering a fluid may include a filter body made up of a folded filter material. The filter element may also include a circumferential edge and a side edge running in a circumferential direction along the circumferential edge. The side edge may have at least one strip portion, running along the side edge, with a side strip that may be separate from the filter body and arranged on the filter body. The side edge may also have at least one adhesive portion running along the side edge for sealing the filter body. The at least one adhesive portion may be formed by gluing of least two folds, adjacent along the side edge, in a region of the side edge.

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.

Abstract: An arrangement for a fluidic and mechanical connection of two components may include a first component, a second component, and a coupling. The coupling may include a first coupling part arranged on the first component and a second coupling part. A damping part may moveably connect the second coupling part to the second component. An axial overlap region may be formed between the damping part and the second coupling part, which axially on the side facing the first component is bounded by a connecting region for realizing a mechanical connection between the second coupling part and the damping part. The second coupling part may coaxially plug into the first coupling part for fluidic and mechanical connection. At least one sealing element may be radially arranged between the first coupling part and the second coupling part.

Abstract: A filter element of a filter device for filtering a fluid may include a ring-shaped filter body from a filter material. The filter body may enclose an interior space in the circumferential direction. A main port may be fluidically connected to the interior space and an auxiliary port may also be fluidically connected to the interior space. The filter body may include a duct that extends axially and is radially open. The auxiliary port may be arranged in a region of the duct.

Abstract: A plate filter element for a filter device may include a filter body having a peripheral edge, which has at least two rectilinear wall sections, which border each other and forming a corner. A seal may be attached to the filter body and be arranged peripherally along the edge. The seal may have an inner contour running around the inside and an outer contour running around the outside. The inner contour may run parallel to the rectilinear edge sections into the respective corner. The outer contour may run parallel to the rectilinear edge sections to a corner region, which contains the respective corner and end sections of the rectilinear edge sections border the respective corner regions. The outer contour may form a bulge, which curves outwards in relation to rectilinear sections of the outer contour, in the corner region.

Abstract: An air filter for a fresh air system of an internal combustion engine may include a housing having a first housing shell and a second housing shell. An intermediate panel may be disposed therebetween separating a crude chamber from a clean chamber in the housing. The intermediate panel may have a passage opening. A filter element may be arranged in the passage opening, and the filter element may include a surrounding seal. The intermediate panel may include a surrounding seal contour on an inside edge bordering the passage opening, and the seal may rest on the seal contour. A fixing frame may be configured as a separate component with respect to the intermediate panel, the two housing shells, and the filter component. The fixing frame may encompass a side of the seal facing away from the seal contour along the filter element and be secured to the intermediate panel.
