The invention relates to a thermostatic safety valve for controlling a mass flow, having a housing (12) which has an inlet opening (14) and an outlet opening (16), having a passage opening (17) which connects the inlet opening (14) and the outlet opening (16) so as to be traversed by a mass flow, and having a valve seat (18) which is arranged in the passage opening (17), which valve seat (18) can be closed off by means of a valve element (19), wherein at least one actuating element (31) acts between the valve element (19) and the housing (12), which actuating element (31) can be arranged in a self-holding fashion in at least one defined end position (32, 37) and, in the one end position (32), positions the valve element (19) in an open position (34) with respect to the valve seat (18), and in the further end position (37), positions the valve element (19) in a closed position (36) with respect to the valve seat (18), wherein a thermal actuating member (28) engages on the valve element (19), which thermal actuating member (28), as a function of the temperature of the mass flow, generates at least one actuating movement of the valve element (19) and moves the valve element (19) into the first end position (32) or the second end position (37). |
