Abstract

Improvements introduced in the servo addresses for accumulator service; especially for motor vehicles, with a distribution valve, which is closed in the neutral position, for the distribution of the pressure medium to the cylinder chambers of the servomotor characterized in that the distribution valve is provided with two cylindrical pistons that are arranged symmetrically with respect to a maneuver pin and that with its front surface, located on the opposite side to the maneuver pin, are subjected to the accumulated pressure, each time a closed circuit valve is provided between the return duct and the behavior that leads to the respective cylinder chamber.
