Abstract
A pressure-limiting valve has a closure member (5) which, in its closed position, rests with initial stress against a valve seat (4) and has, on the side towards the valve seat (4), a shoulder (6) which can be formed by a circumferential flange (7) on the closure member (5). This induces enlargement of the opening stroke upon a slight opening of the closure member (5) as the flow strikes against the shoulder (6).
