Abstract

Dispositif hydraulique pour la commande d'un frein ou d'un accouplement et pour l'alimentation d'un consommateur de fluide hydraulique. Selon l'invention, ce dispositif est caractérisé en ce que la conduite d'alimentation d'un consommateur de fluide hydraulique fonctionnant avec une partie de la pression de l'accouplement est branchée en dérivation sur la conduite de pression de la pompe et le dispositif de commande de pression est agencé dans ladite conduite d'alimentation et comporte, entre le raccord de la conduite d'alimentation dirigée vers la pompe et celui dirigé vers l'utilisateur, un organe de réglage relié à un piston différentiel commandé d'un côté par la pression de la conduite d'alimentation, et en ce que le côté d'alimentation de la soupape de réglage est reliée à la conduite de commande entre la soupape de prémanoeuvre et l'accouplement ou le frein. Commande et alimentation simultanée de frein, accouplement et consommateur de fluide hydraulique.
