Claim 0:
1. A filter element for an oil separator of a crankcase ventilation system, the filter element comprising:
at least one filter medium surrounding a central axis, the at least one filter medium configured to separate oil from aerosol, the at least one filter medium having an axial end surface forming a covering surface extending in a radial direction relative to the central axis;
a cover element formed as an annular end plate, fixed onto and fully covering the covering surface of the at least one filter medium; and
a tubular projection projecting axially outwardly away from the cover element and the at least one filter medium, the tubular projection having an open interior which opens through the cover element into an interior of the at least one filter medium, wherein the tubular projection is a clean fluid discharge element configured to remove cleaned fluid from an interior of the filter element;
wherein an axially outer end of the tubular projection of the filter element has an annular sealing surface forming a valve seat;
wherein the tubular projection is configured as a clean fluid discharge element that extends away from the filter element and is configured to remove cleaned fluid from an interior of the filter element to the valve seat of the cover element;
wherein the valve seat of the cover element is configured as a sealing surface for a pressure control valve body of the crankcase ventilation system to sealably close against.
