Abstract
(EN)
A device comprising an actuating cylinder (10) having a piston (14) arranged to be driven along a stroke path therewithin and a valve means (50) for controlling the flow of actuating fluid to a first side (20) of the piston (14). This device is arranged such that upon actuation of the valve means (50) the flow of actuating fluid to the first side (20) of the piston (14) is stopped and wherein the pressure of the actuating fluid on the first side (20) of said piston (14) upon actuation of said valve means (50) is at least sufficient to substantially maintain the piston (14) in a first predetermined position along the stroke path.
(FR)
Le dispositif de l'invention comprend un cylindre d'actionnement (10) ayant un piston (14) ayant une course d'entraînement à l'intérieur du cylindre et des moyens à soupape (50) pour commander l'écoulement du fluide d'actionnement sur un premier côté (20) du piston (14). Ce dispositif est agencé de telle sorte que, en actionnant les moyens à soupape (50), l'écoulement du fluide d'actionnement vers le premier côté (20) du piston (14) est arrêté et la pression du fluide d'actionnement sur ce premier côté (20) du piston (14) est au moins suffisante pour maintenir le piston (14) dans une première position prédéterminée sur le chemin de la course du piston.
