Abstract
Ce dispositif hydraulique est destiné à commander un vérin 10 monté par exemple sur une grue à compensation de houle munie d'une pompe réversible 20 à à cylindrée variable reliée au vérin par un conduit 21; un conduit 23 la relie à un distributeur 35 qui peut alimenter la pompe par un réservoir à basse pression 22 ou par des accumulateurs à haute pression 40 et 50. La pression des accumulateurs pouvant être à certains moments supérieure à la contre-pression de la charge, des moyens sont prévus pour éviter que la pression d'alimentation ne fasse tourner la pompe en maintenant la pression à la sortie de la pompe supérieure à celle de l'entrée de cette pompe quel que soit le sens de fonctionnement de celle-ci. Il est encore prévu des circuits de surpression évitant la surcharge de la pompe et de la grue.
