Abstract

Dispositif comprenant un moyen (55) régulant la pression dans la chambre (12) à partir de la pression dans le carter (3) en fonction de la commande d'accélérateur et permettant ainsi une commande directe de la quantité de carburant injectée en fonction de l'accélérateur; ce moyen placé dans le canal (19) est doublé d'un conduit entre la chambre (12) et le carter (3), lequel conduit est muni d'un clapet (56) permettant le passage de l'air de la chambre (12) vers le carter (3) mais bloquant le passage du carter (3) vers la chambre (12). Dispositif comprenant un moyen (42) commandé par la poignée des gaz et permettant de régler la contrainte du ressort (15).
