HYDRAULIC BALL LOCK FOR CONNECTING AND DISCONNECTING SECTIONS OF AIRBORNE EQUIPMENT

Abstract : The object of the invention is a hydraulic ball lock for connecting and disconnecting sections of flying (airborne) equipment which has a spring piston compressing in the radial direction balls, which are located in openings in the cylinder of the piston. For the purpose of simultaneously connecting and disconnecting several connecting tenons of sections of the airborne apparatus, it is provided with a stationary race and a race held movable by balls, set on the outer surface of a cylinder, these races holding on the cylinder segments of the connecting tenons, such segments forming in the closed position of the lock a ring with two cones, which enter the inner conical bores of the races. A pneumatic differential piston, which acts on a volume of operating fluid included in the bore of the spring piston is used as a reinforcer of the lock.
