Abstract
The distributor (10, 11), typically with a star-type rotor in a discoid stator, incorporates a valve means with an OR logic function (5, 5') of preselection of the direction of the reaction (22, 23) to be applied to the input component as a function of the relative displacement between the primary and secondary components of the distributor, formed in one piece with the distributor and consisting of pairs of edges cooperating between two cavities (39a, 39b) of the stator (28, 30) and a cavity (44) of the rotor (31) advantageously formed in a reaction arm (41) of this rotor and permanently communicating with the source of pressure (14) of the distributor via a restriction (4) which can be externally modulated. The restrictions (5, 5') providing the OR logic function come into operation first, before the actual distribution restrictions (1, 2, 3; 1', 2', 3') of the distributor supplying the assistance actuator (19).
