Abstract

Le dispositif de commande pour un vérin hydraulique présente une soupape d'arrêt (10) dans laquelle un corps de soupape (40; 40A; 40B) coopère avec un siège de soupape (41) solidaire du corps. Dans le corps de soupape est placé un élément de soupape pilote (72; 72A; 72B), lequel coopère avec un siège de soupape (73; 73A; 73B) également disposé dans le corps de soupape, ainsi qu'avec des orifices d'étranglement (63, 64; 118, 119; 63B, 64B). Les efforts de pression exercés sur l'élément de soupape pilote sont compensés, de sorte que ce dernier puisse être actionné par un aimant proportionnel (13).
