Improvements in the mechanisms for the operation of automatic passage barriers, essentially characterized by the fact that they comprise a hydraulic circuit in which a cylinder is interposed, whose corresponding piston moves alternately working by direct control of the alternative hydraulic pressure on each side of the same, to which end the hydraulic circuit that governs said piston, comprises two branches of communication, one for each head of the cylinder, and related to a gear pump or other, working alternately from right to left by the action of an engine The inverter contactor is designed to rotate in one direction or another alternately, eliminating any intermediate or two-step valve.
