Abstract
A liquid filter including a valve arranged in a supporting tube of a filter insert, in which the valve is fixed by a disk (60) which is oversized relative to a mounting opening (61), so that reliable sealing to the edges of the disk is facilitated. Use of the disk (60) simplifies the mounting of the valve.
