Abstract

Circuit hydraulique de commande multiple pour alimenter des récepteurs avec du liquide hydraulique fourni par une pompe à débit commandé par la pression (PLS) de la ligne de commande (LS) dépendant de la pression de charge des récepteurs (Ri) et débitant le liquide hydraulique à la pression réglée. Le circuit étant composé de modules hydrauliques (Mi) associés chacun à un récepteur ayant un distributeur qui règle le débit variable alimentant le récepteur (Ri) à travers un compensateur de pression (15), relié en entrée (U) à la sortie de l'étranglement variable (20) du distributeur (11) et en sortie (V). Le plongeur (150) gère la communication entre son entrée (U) et sa sortie (V). Le compensateur de pression (15) a une liaison fluidique (31, 32) munie d'un étranglement (33, 33a) et reliant la sortie (V) à la ligne (LS), quelle que soit la position du plongeur (150).
