Abstract: The invention relates to a compact filter element (1) for exchangeable use in a filter housing (2). The compact filter element (1) has a filter body (3) with a longitudinal axis (7) and at least one seal (4) arranged in the area of a front end (5) of the filter body (3), the seal having a seal section (8) which is arranged across the width (10) of a housing wall (6), sealing same. The seal section (8) projects beyond a front surface (12) of the filter body (3) in the direction of the longitudinal axis (7). The seal section (8) has a peripheral support wall (9) and at least one seal lip (17) integrally bonded to the outside of the support wall (9), across the width (10) of the latter, wherein the support wall (9) and the seal lip (17) consist of a rubber elastic material.

Abstract: A filtering device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A cover disk closes off the filter housing. The cover disk consists of two individual disks and a central flow connection connects the two individual disks. The two individual disks and the flow connection form a common plastic component.

Abstract: A filter device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A liquid to be filtered is introduced into the filter housing and flows through the filter element. An overflow valve is arranged between an entry side and a clean side of the filter element and has a valve body. The overflow valve is in an open position when a pressure of the liquid at the entry side of the filter element exceeds a threshold value. The valve body of the overflow valve is a sealing hose placed between the entry side and the clean side onto a cylindrical supporting body arranged in the filter housing. Flow openings are provided in the cylindrical supporting body. The sealing hose is arranged at the clean side of the supporting body.

Abstract: Disclosed is a filter device, especially for filtering liquids in internal combustion engines, comprising a filter element (4) that is to be penetrated in a radial direction and is disposed in a filter housing (2). A check valve (10) which is embodied as a nozzle valve and is provided with flexible wall sections is inserted into the filter housing. The internal faces of said flexible wall sections define a flow outlet while the external faces thereof are in contact with the liquid in the filter device.
