Abstract

Le dispositif comporte une soupape d'arret commandée pour l'ouverture par un piston de commande et bloquant le cylindre de travail par rapport au conduit de pression. La chambre coté sortie de la soupape d'arret est raccordée à un canal de décharge et de controle de fuite commandé par une soupape auxiliaire accouplée au piston de telle façon qu'il soit ouvert lorsque la soupape d'arret est fermée et fermé lorsque celle-ci est ouverte. L'écoulement de liquide à l'extérieur, par ce canal, indique une perturbation de fonctionnement par manque d'étanchéité de la soupape.The device comprises a shut-off valve controlled for opening by a control piston and blocking the working cylinder relative to the pressure conduit. The chamber on the outlet side of the stop valve is connected to a discharge and leakage control channel controlled by an auxiliary valve coupled to the piston so that it is open when the stop valve is closed and closed when that -this is open. The flow of liquid to the outside, through this channel, indicates a disturbance of operation by lack of tightness of the valve.
