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 (), a combustion chamber (), a piston () capable of moving in a slide chamber () under the effect of said gas, the two chambers () being in communication with each other. The main characteristic of this actuator is that it comprises a shutter device () implemented after said actuator () has been triggered to interrupt the communication between said chambers (), said shutter device () being included in the slide chamber ().
