Abstract

Ce dispositif comprend un piston 14 en liaison d'entraînement avec une soupape du moteur, ce piston étant monté dans un cylindre dont une extrémité peut être reliée à une source de fluide sous pression au moyen d'une soupape de commande 20. La même extrémité du cylindre peut être reliée à un conduit de vidange par l'intermédiaire d'une autre soupape de commande 29 afin de permettre la fermeture de la soupape du moteur. Suivant un mode de réalisation, un ressort est utilisé pour fermer cette soupape et dans un autre exemple, cette dernière est sollicitée vers sa position de fermeture par une force exercée sur un piston secondaire par un fluide sous pression.This device comprises a piston 14 in a drive connection with an engine valve, this piston being mounted in a cylinder, one end of which can be connected to a source of pressurized fluid by means of a control valve 20. The same end of the cylinder can be connected to a drain line through another control valve 29 to allow the engine valve to close. According to one embodiment, a spring is used to close this valve and in another example, the latter is urged towards its closed position by a force exerted on a secondary piston by a pressurized fluid.
