Abstract

Abstract Translated from French Le distributeur, avantageusement du type à rotor en étoile, comprend deux éléments coopérants définissant deux circuits de fluide en parallèle (10;11) entre une source de pression (12) et une bâche et (13) incluant chacun trois restrictions en série (1,2,3;1'2',3') actionnables lors du déplacement relatif des deux éléments, et, pour chaque circuit, une restriction supplémentaire (EV;EV') en parallèle avec la seconde restriction (2;2') et modulée par des moyens de commande extérieurs -sensibles par example à des conditions de marche d'un véhicule- pour modifier sélectivement la position du point de transition entre les première et seconde portions de la courbe caractéristique pression d'assistance délivrée (15;16) par le distributeur/réaction sur l'organe de commande du distributeur (14). The distributor, advantageously of the star rotor type, comprises two cooperating elements defining two fluid circuits in parallel (10; 11) between a pressure source (12) and a tank and (13) each including three restrictions in series (1 , 2,3; 1'2 ', 3') actuable during the relative displacement of the two elements, and, for each circuit, an additional restriction (EV; EV ') in parallel with the second restriction (2; 2') and modulated by external control means - sensitive for example to running conditions of a vehicle - to selectively modify the position of the transition point between the first and second portions of the assistance pressure characteristic curve delivered (15; 16) by the distributor / reaction on the distributor control member (14). Application notamment aux servo-directions de véhicules. Application in particular to the power steering of vehicles.
