FIELD: aeronautical engineering.
SUBSTANCE: proposed actuator has body with distributing and locking device, hydraulic cylinder, system for monitoring the locking device position, cross-feed valve and cut-in valve with sleeve where plunger with spring is arranged. Cut-in valve is made in form of three-bead pusher with adjusting screw at end face which is located inside spring-loaded plunger; seat of plunger is provided with bore whose diameter exceeds diameter of pusher; this bore is connected with return line through variable restrictor formed by edge of bore and bead of pusher and permanent restrictor in form of orifice in pusher. Bore is connected with pressure line through permanent restrictor in plunger body and circular chamber formed by plunger beads.
EFFECT: enhanced reliability.
