Abstract

Mécanisme de commande à soupapes pour moteur à combustion interne suralimenté. Il comporte plusieurs soupapes 74 qui commandent des circuits d'écoulement de fluide aboutissant à des dispositifs de régulation de certaines fonctions du moteur. Le mécanisme est conçu de manière que, lorsque la pression régnant dans le circuit d'aspiration d'air et de carburant croît pour passer d'une valeur négative à une valeur positive, les circuits de commande soient fermés afin de faire cesser le fonctionnement des dispositifs ainsi pilotés. Domaine d'application : moteurs à combustion interne suralimentés.
