<p>The distributor, typically one having a star-shaped rotor in a disc-shaped stator, incorporates two components, primary and secondary, defining two parallel distribution circuits (10, 10') controlling an assistance actuator (V) and incorporating, in each circuit, three variable restrictions (1-3 or 1'-3'), together with, advantageously, two other parallel reaction circuits (20, 20') with two restrictions in series (4, 5 and 4', 5'). The chamber (V1, V2) of the assistance actuator (V) are joined to the distribution circuits (10, 10'), respectively, between the second (2, 2') and third (3, 3') variable restrictions which create the differential assistance pressure, the central point of the distributor being determined by the first (1, 1') and second (2, 2') variable restrictions.</p> |
