Abstract
Dispositif de commande hydraulique d'un servo-moteur, notamment pour des directions de véhicules, ce servo-moteur 1 comportant deux canalisations de raccordement 2, 3, un circuit de commande 4, un circuit de travail 5 et une pompe commune à débit fixe 6 qui alimente ces deux circuits, ainsi qu'un circuit supplémentaire 8 d'un servo-moteur de levage 7. La pompe 6 alimente le dispositif de réglage de pression 23 du circuit de travail 5, le dispositif de réglage de débit 10 du circuit de commande 4 et la soupape d'actionnement du circuit supplémentaire 8 par l'intermédiaire d'une soupape de priorité 49 commandée par un diaphragme 18 du circuit de commande, de manière à alimenter soit le circuit supplémentaire, soit les circuits de travail et de commande. Application : direction hydraulique de véhicules.
