ABSTRACT:
A device for actuating a movable mechanical member, using a fluid source such as a gas generator of a missile, of the type having a controllable distributor connected to the source. The device includes a body (11) provided with a distributor (12), the body being coupled, via an inlet orifice (17), to a fluid source; a first conduit (15) capable of connecting the inlet orifice to a chamber (16) of the distributor; an actuator cylinder (14) arranged in the body and including a first chamber (19A) and a second chamber (19B) which are coaxial and separated from each other by a sliding piston (31) connected to a rod (31B) which projects externally in relation to the body in order to be linked to a mechanical member. A second conduit (18) connects the chamber (16) of the distributor to the first chamber (19A) of the actuator cylinder, it being possible for the second conduit (18) to be brought into communication, via the chamber (16) of the distributor, either with the first conduit (15) or with an outlet orifice (20) outside the body, depending on the position of the distributor. A third conduit (21) connects the second chamber (19B) of the actuator cylinder to the inlet orifice (17) of the body.
