Abstract

La commande comporte un cylindre d'entraînement 8 avec un piston d'entraînement 2 commandé par une came 1, un piston de travail 33 actionnant la soupape 32, et un réservoir 31, le cylindre d'entraînement étant en communication permanente avec un accumulateur 27 présentant un orifice de sortie 29 avec un point d'étranglement, le piston d'entraînement étant entouré par deux douilles de commande 6 et 7 destinées à déplacer le début d'ouverture et de fermeture de la soupape, tandis que dans le cylindre de travail est disposée une douille de commande entourant le piston de travail et destinée à modifier la course de la soupape.
