Abstract

The invention relates to a check valve with a curved washer (43) pressing a valve closing member (24) against a valve seat (30). To reduce the closing time and reduce the impact of the valve closing member (24) on closing, the invention proposes a transverse shoulder (66) limiting the valve travel.
