FIELD: nuclear or power engineering.
SUBSTANCE: actuator comprises three plates. The top and bottom plates are secured by means of studs. The intermediate plate is mounted for permitting movement along the studs. The actuator is also provided with gas collector which is connected with the air distributor and made in the top plate. The air-operated drive additionally has branch pipes. The first branch pipe is connected with the face of the rod of the piston of the air-operated drive. The rod is hollow and provided with openings in its side and at its end. The second branch pipe is set in the axial hole which is made in the cylinder base opposite to that provided with the opening for passing the rod of the piston. The rod of the air-operated drive is set in the opening of the collector or in the opening made in the intermediate plate. The cylinder is set in the opening in the intermediate plate or in the opening in the collector.
EFFECT: enhanced reliability and expanded functional capabilities.
