PCT No. PCT/DE92/00757 Sec. 371 Date Aug. 25, 1994 Sec. 102(e) Date Aug. 25, 1994 PCT Filed Aug. 9, 1992 PCT Pub. No. WO93/10386 PCT Pub. Date May 27, 1993The pressure-relief valve (10) has a valve member (18), which interacts with a valve seat (17). The valve member (18) is forced with a certain pretensioning against the valve seat, which pretensioning is applied by way of a diaphragm (21), either directly by this or by virtue of an additional spring means. Whenever a predefined maximum pressure is exceeded, the diaphragm (21) comes to bear against a stop face (26). Due to the free guidance of the valve member (18) tight, contamination-sensitive gaps are avoided. Although the pressure-relief valve is compact, secure bearing contact of the valve member against the seat is nevertheless ensured (FIG. 1).
