ABSTRACT:
The technical field of the invention is that of pyrotechnic actuators including a piston and having the essential function of exerting thrust to move an object by causing the piston to emerge. The invention relates more particularly to a pyrotechnic gas generator (2), a combustion chamber (3), a piston (10) capable of moving in a slide chamber (4) under the effect of said gas, the two chambers (3, 4) being in communication with each other. The main characteristic of this actuator is that it comprises a shutter device (5) implemented after said actuator (1) has been triggered to interrupt the communication between said chambers (3, 4), said shutter device (5) being included in the slide chamber (4).
