ABSTRACT:
The distributor (10), typically with a star-shaped rotor in a discoid stator, comprises a reaction device (11) advantageously integrated in the distributor and providing the actuating member (17) of the distributor with a reaction opposite to the actuating torque exerted on this actuating member and proportional to the power-assistance force supplied by a jack (12) controlled by the distributor (10). A regulating valve (30, 31) is associated with the reaction device (11), being typically located upstream of the latter, and is put into effect when the reaction force applied by the reaction device reaches a maximum predetermined value, in order to limit the reaction force to this predetermined value.
