Abstract

A linear pneumatic actuator with a reversible-action locking device for presetting of the actuator with an active or passive brake. The actuator comprises a piston (13) which may reciprocate inside a cylinder (10); the linear movement of the piston (13) causes rotation of a threaded shaft (20) connected to a signal generator (25) which continually supplies the relative position of the piston (13). A locking device comprises two interconnected piston members (34, 36) which can be pneumatically actuated in opposite directions and ducts (46, 47) supplying pressurised air which can be selected during assembly so as to activate the locking device as an active brake or passive brake, respectively, in order to block the actuator piston (13). <IMAGE>
