Abstract
The application is directed towards a filter element which has an oval cross-section and a circumferential sealing device for sealing the filter element off from a filter holder for the filter element, wherein the sealing device has a plurality of curvature sections to ensure good sealing. The application is also directed towards a filter assembly utilizing such a filter element.
Claims18
A filter element comprising:
- an open first end plate;
- a closed second end plate;
- filter media being arranged between the first end plate and the second end plate;
- and
- a seal member arranged on a front side of the first end plate facing away from the filter media, the seal member having an oval profile;
- wherein the first end plate includes an opening such that a working fluid may flow into or out of the filter media;
- wherein the filter media is configured to allow the working fluid to be filtered through the filter media;
- and
- wherein the seal member comprises at least two pairs of curvature formed on an inner perimeter thereof, and wherein the at least two pairs of curvature sections comprise outwardly curved surfaces and have different degrees of curvature;
- and
- wherein a joining location between different curvature sections does not comprise an outwardly surface.
