Abstract: A filter system for liquid has a filter head with drainage channel and stop element. A filter cartridge is mounted by screw-in movement at the filter head and has a support ring rotatably fastened to its housing part. The support ring has an eccentric closure element and a first positioning element guided toward the stop element by the screw-in movement to position the support ring at the filter head in a rotational position for axially aligning closure element and drainage channel. The closure element is transferred axially into a sealing seat at the filter head to close the drainage channel when screwing on the filter cartridge. The support ring has a second positioning element holding the support ring in a rotationally fixed position at the filter head when unscrewing the filter cartridge so that the closure element is moved out of the sealing seat only in an axial direction.

Abstract: A filter element for filtering a fluid is connectable to a filter head with a drainage channel. The filter element has a closure element that closes the drainage channel of the filter head when the filter element is connected to the filter head. The closure element is eccentrically arranged relative to a longitudinal axis of the filter element at an end face of the filter element. The closure element extends away from the end face of the filter element in an axial direction of the filter element. A stand is locked at the filter element and extends away from the end face of the filter element in the axial direction to a level of a free end of the closure element or past the free end of the closure element.
