Abstract: A filter element has a filter bellows with circumferential seal having a seal region and a fastening region with radial and axial fastening sections. The radial fastening section has a holding surface facing away from the filter bellows and engaging a radially inner pressure-exerting section of a housing. The axial fastening section provides a radially inner boundary of a circumferential groove of the seal region that receives a radially outer pressure-exerting section of the housing. A seal projection forms a radially outer boundary of the groove. The seal region has an axially acting sealing surface opposite the groove axially spaced farther from an axial filter bellows end face than the holding surface. Axial spacing between groove base and axially acting sealing surface is greater than a spacing between a transition of the groove base into the axial fastening section and a transition of the holding surface into the seal region.

Abstract: A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material.

Abstract: A filter device is provided with a filter housing and a housing cover closing off the filter housing. A filter element is disposed in the filter housing. The filter element comprises a first form-fit part projecting past an outer wall surface of the filter element. The housing cover is provided with a second form-fit part correlated with the first form-fit part. The first and second form-fit parts engage each other in a mounted state of the filter element on the housing cover. The first form-fit part is a laterally projecting hook.

Abstract: A filter device is provided with a filter housing and a housing cover closing off the filter housing. A filter element is disposed in the filter housing. The filter element has a clamping element that is resting with a clamping force on a first housing part that is provided on the filter housing or on the housing cover. The filter element further has a lever element that, in the mounted state of the filter element in the filter housing, is resting on a second housing part that is provided on the filter housing or on the housing cover and force-loads the clamping element against the first housing part. The clamping element and the lever element form a single part and are preferably provided on an end disk of the filter element.

Abstract: A filter housing has first and second housing parts connected to each other to be openable and secured by a latching element. The latching element is connected to the first housing part by a moveable connection with a predetermined breaking point and is pivotable by the movable connection into the closed state. The latching element has two positioning elements and the housing parts have counter positioning elements. In the closed state, the counter positioning elements are axially arranged between the two positioning elements and the positioning elements form a stop for the counter positioning elements. The latching element has an element locking section locking at a housing locking section on the first or second housing part. The predetermined breaking point is subjected to mechanical stress such that the predetermined breaking point breaks upon locking or release of the latching element.
