Abstract
Improvements in control valves for power steering of vehicles, of the type comprising a distributor body, connected in rotation with the driving spindle of a steering box and comprising, on the one hand, ducts connected with opposite chambers of a fluidic actuator of double effect, associated with the steering mechanism to help the spindle, and by the other inlet and outlet ducts of fluid under pressure, and a control member, attached to the steering wheel and associated with the distributor so that it is suitable for communicating the inlet and the outlet of pressurized fluid with opposite working chambers of the actuator, essentially characterized by the fact of developing the distributor body as a discoidal chamber and the star-shaped rotor-like control member whose arms adjust with the surfaces of the discoidal chamber defining circumferentially distributed and hermetic chambers with each other, is alternating cameras in communication with respective working chambers of the servo-actuator, and having at least one of the axial surfaces of the distributor chamber having circumferentially distributed ports, connected alternately with the fluid inlet and outlet and arranged in angular positions such that in the rest position are closed substantially 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, the distributor chamber and the arms of the star rotor being designed so that the circumferentially opposed surfaces of each two adjacent arms are different, so that the fluid pressure prevailing in the circumferential chambers that in an operating position communicate with the pressurized fluid inlet, produce on the surface arms greater a reaction that is it puts the driving effort of the steering and is proportional to the steering angle thereof and/or to the operating pressure of the driving fluid.
