Abstract: A safety valve for a pressurized gas container is disclosed having a crossflow channel (1) which is connected to the pressurized gas container and having at least one outlet channel (2) and having a thermal triggering unit (3, 101, 102) which has a closure body (101) which can be displaced from a readiness position, in which, in interaction with a sealing element (5), it keeps the crossflow channel (1) tightly closed with respect to the at least one outlet channel (2), into a release position, in which the crossflow channel (1) is connected to the outlet channel (2), and which thermal triggering unit (3, 101, 102) has a rupture body (3) which is arranged between an abutment (4) and the closure body (101), in order to hold the latter in the readiness position, wherein the thermal triggering unit (3, 101, 102) comprises a spring element (102) which exerts a spring force on the rupture body (3), which spring force is oriented in the direction of the abutment (4).
