A closure member (5) for a valve seat (4) has a spindle (6) which with a closer spring (7) and a flow pipe (8) extend into a vessel (1) from a housing (3) which has a lateral opening (11) in which a rupture member (12) is secured. In the event of excessive pressure in the space (10), the disc (12) will rupture and the valve member (5) can be forced off its seat (4) by the pressure in the space (10). <IMAGE> |
