Abstract

L'invention concerne un distributeur pour directions assistées comportant un vérin non équilibré. Une pression différentielle des deux chambres de travail 11 et 11' du vérin de direction 12 est établie par deux étranglements dont l'un 16 est intercalé entre la chambre 11 du vérin 12 présentant la surface efficace la plus petite et un conduit de retour 15 et dont le second 16' est monté en aval du conduit 8 d'admission du fluide de travail et en amont d'un branchement 13' d'un conduit 10' reliant la chambre 11' présentant la surface efficace la plus grande à l'arête de retour 14'. Application aux directions assistées de véhicules.
