Abstract

Dispositif de commande hydraulique d'un servo-moteur 1, notamment de direction de véhicule, comportant un circuit de commande 7, comprenant un dispositif de réglage de débit 8 et deux soupapes de commande 20, 21, un circuit de puissance 22, comprenant un régulateur de pression 29, deux soupapes principales 23 et 24, auxquelles sont associés deux éléments de rappel 46, 47, et un régulateur de pression 29. Le réglage de débit 9 comporte un conduit 17 qui, en position neutre, fait communiquer les tubulures de raccordement de commande 13, 14 avec la tubulure de raccordement 11 du réservoir. Application : commande hydraulique de direction, notamment de véhicules.
