FIELD: aeronautical engineering. ^ SUBSTANCE: proposed actuator is provided with distributing device, cylinder with actuating rod, locking device and cross-feed valve. Locking device is made in form of two systems of levers located symmetrically relative to actuating rod and secured on cylinder; they are engageable with rollers secured on rod. Each lever system consists of double-arm levers; one arms are linked by means of rod and other arms are articulated with spring-loaded piston of locking device control cylinder and with three-arm levers by means of adjustable stops; first arms of three-arm levers are interconnected by means of springs and second arms are connected with unit for monitoring operation of locking device, third arms are provided with bevels engageable with roller secured on actuating rod. ^ EFFECT: enhanced reliability. ^ 1 dwg |
