Abstract

Improvements in control valves for power steering of vehicles, of the type comprising a distributor member, connected in rotation with the driving spindle of a steering box and comprising, on the one hand, communicating ducts with opposite chambers of a fluidic actuator of double effect, associated with the steering mechanism to assist the spindle, and on the other communicating ducts with a fluid inlet and outlet under pressure, and a control member, attached to the steering wheel and associated with the distributor of this means is suitable for communicating the inlet and the outlet of pressurized fluid with opposite chambers of the actuator, characterized essentially by the fact of developing the distributing member as a discoidal chamber, and the rotor-shaped control member as star whose arms a-just with the surfaces of the camera defining circumferentially distributed and hermetic cameras each other, with alternate chambers in communication with respective chambers of the servo-actuator, and having at least one of the axial surfaces of the chamber circumferentially distributed ports, connected alternately with the fluid inlet and outlet and arranged in angular positions such that in the resting positions are substantially closed by the arms of the star rotor, and in each of the operating positions communicate the inputs and outputs with the corresponding cameras to one or the other side of the servo-actuator.
