Abstract

Distributeur pour direction assistée fermé en position centrale et comportant au moins un clapet et deux organes tournant 22, 23 l'un dans l'autre. Ces organes sont des éléments d'un tiroir rotatif qui définit des étranglements à section variable réglant le débit du liquide qui revient du servomoteur et qui peut constituer un répartiteur du liquide envoyé à ce servomoteur et en revenant Application notamment aux automobiles de tourismeDistributor for power steering closed in the central position and comprising at least one valve and two rotating members 22, 23 one inside the other. These members are elements of a rotary slide which defines constrictions with variable section regulating the flow rate of the liquid which returns from the booster and which can constitute a distributor of the liquid sent to this booster and returning Application in particular to passenger cars
