Abstract

An oil filter assembly (10) has a receiving chamber that can be closed by a cover element and a spring-loaded supporting tube (22) that is fixed in the receiving chamber (18) and is designed to receive a filter element (20) that can be radially traversed by oil, the supporting tube being 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 (14), the tube closes a drain opening (42) and when the receiving chamber is open in the drain position, the tube releases a drain opening (42). The cover element (14) has a supporting tube contact area (58) on the side facing the receiving chamber in such a way that during the closing of the receiving chamber (14) when the filter element is located on the supporting tube (22), pressure is exerted on the tube by the support tube contact area (58), thus displacing the tube into the operating position.
