Abstract
An oil filter assembly () has a receiving chamber () that can be closed by a cover element () and a spring-loaded supporting tube () that is fixed in the receiving chamber and is designed to receive a filter element () that can be radially traversed by oil. The supporting tube () is axially displaceable between an operating position and a drain position in such a way that, in the operating position when the receiving chamber is closed by the cover element (), the tube closes a drain opening (). When the receiving chamber is open in the drain position, the tube releases the drain opening. The supporting tube is mounted to rotate through a rotational angle that is limited by two rotational stops () in the housing and the cover element has follower sections () that co-operate with the supporting tube and/or filter element to rotate the supporting tube through the rotational angle when the cover element is screwed on and/or unscrewed.
