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). Said safety valve is distinguished by the fact that the spring element (102) acts on the closure body (101), in order to exert on the latter a spring force which acts in the triggering direction. This embodiment ensures that the safety valve triggers reliably by means of the force which is exerted on the closure body (101) by the spring element (102), even in the case of a relatively low gas pressure in the crossflow line (1) and therefore a low force which acts on the closure body (101).
