Abstract
The invention relates to a triggered-stroke actuator (10) comprising a body (12) housing a piston (14) and a rod (16), and a gas generator (18) mounted in said body (12) opposite said piston (14) and capable of pressurising a first chamber (20) defined between said gas generator and said piston, in which the piston (14) comprises, on its external face, a groove (30) in which is housed a sealing joint (40) with the body (12) of the actuator (10). A calibrated passage (50), adapted to evacuate gas from the first chamber (20), is formed between the sealing joint (40) and the wall of the groove (30).
