Abstract

Dispositif servant au déplacement de la came d'une machine hydraulique et comportant un seul étranglement parcouru dans les deux sens. La douille de commande 13 est manoeuvrée par un levier 15. Avec le piston 18, elle constitue une liaison entre la haute pression et une chambre 52, ou entre celle-ci et un espace sans pression. L'étranglement 21 se trouve dans chacune des deux liaisons. Une soupape de limitation 55 permet une commande de sécurité, avec échappement à faible débit.Device used to move the cam of a hydraulic machine and comprising a single throttle traversed in both directions. The control sleeve 13 is operated by a lever 15. With the piston 18, it constitutes a connection between the high pressure and a chamber 52, or between the latter and a space without pressure. The constriction 21 is found in each of the two links. A limiting valve 55 allows a safety control, with low flow exhaust.
