Patent ID: 8770415

Claim:
A filter element configured for installation into a filter housing of a liquid filter, said filter housing having a filter cup and a filter head, said filter element comprising a substantially annular, rotationally symmetrical filter medium closed on at least one axial end by an end disk to seal an axial end face and separate an exterior space outside the filter medium from an interior space inside the filter medium, wherein the end disk has a fluid flow opening which is disposed off-center relative to the axis of the filter medium; wherein the end disk comprises a first end disk layer having an axial outer face and an axial inner face, the axial end face of the filter medium securely embedded into the axial inner face of the first end disk layer, the first end disk layer forming an elastic sealing layer abutting the axial end face of the filter medium; a second end disk layer having an axial inner face arranged directly on and covering the axial outer face of the first end disk layer, the axial inner face of the second end disk layer sealing and firmly secured to the axial outer face of the first end disk layer; wherein the first and second end disk layers form overlaid layers of a multi-layered end disk; wherein the second end disk layer is more mechanically rigid than the first end disk, the second end disk layer defining a fitting formed integrally therewith, the fitting formed on the axial outer face of the second end disk layer and having a bore extending completely through the multi-layered end disk into the interior space of the filter medium; wherein each of the end disk layers having chemical, mechanical and thermal properties optimized for a different selected function; wherein said bore of said fitting of said end disk is in fluid flow communication with said interior space of said filter medium through said opening; wherein said fitting is axially spaced apart from said filter housing; and wherein the axial outer face of the second end disk layer includes centering contours for centering, said centering contours extending axially outwardly away from the axial outer face of said end disk in a direction away from said filter medium and configured to engage with the filter head of the filter housing to axially support the filter element within the filter housing.
