Abstract
The technical field of the invention is that of pyrotechnic actuators comprising a piston, the basic function of which is to exert a thrust so as to displace an object by shooting out the piston. More particularly, the invention relates to a pyrotechnic actuator () comprising a pyrotechnic-gas generator (), a combustion chamber () and a piston () which can move in a slide chamber () under the effect of the said gases. The principal characteristic of this actuator is that it comprises a shut-off device (, 4) used after the triggering of the said actuator () in order, on the one hand, to close the slide chamber () and, on the other hand, to secure the depressurization of the combustion chamber ().
