Abstract
Mécanisme de commande. Le circuit fluidique pour la commande d'un mécanisme de commande comportant un cylindre 28 et un piston 29 avec une tige de piston 30 comprend un ensemble 1 à soupapes de réglage du débit et de réglage de la pression entre une sortie 3 reliée à la chambre du cylindre côté tige du piston et une entrée 2 communiquant avec un distributeur de changement de direction d'écoulement 31 et une source de fluide sous pression 35, et un ensemble 33 à soupapes de retenue et de réglage par étranglement entre la chambre du cylindre côté tête du piston et le distributeur 31, l'agencement étant tel qu'il permette un réglage de la pression du fluide pour la course de retour du piston de façon à réduire l'énergie nécessaire à cet effet. Convient, en particulier, pour un mécanisme de commande d'un travail mécanique.
