ABSTRACT:
Control valve in which the reaction torque is created firstly by hydraulic reaction means and secondly by resilient means to provide for a second gradient of reaction torque; the invention consists in a control valve having a star-shaped rotor rotatably mounted in a disc chamber of a stator to define notably with a constituting member of that chamber several working chambers, the arms of said star-shaped rotor being of unequal lengths to provide for a first gradient of reaction torque, as known per se, and the improvement consisting in that the member is rotatable with respect to a surrounding intermediate member of said stator and that resilient means are located between members to provide for a second gradient of reaction torque.
