Abstract
La présente invention concerne une installation d'injection de carburant. Cette installation comprend un tube d'aspiration 1 comprenant un papillon 2 et un organe de mesure 3 actionnant une soupape de dosage de carburant 7 permettant de doser une quantité de carburant proportionnelle à la quantité d'air aspiré. Une soupape d'équilibrage de pression 11 présente deux chambres 13 et 14 séparées par une membrane 12 pour maintenir constante la pression différentielle dont l'importance est déterminée à l'aide d'une soupape de réglage 20 sollicitée par un ressort 31. Les deux chambres 13 et 14 de la soupape d'équilibrage de pression 11 sont reliées par un by-pass 17 réglable formé par un orifice dans ladite membrane 12. L'invention s'applique aux moteurs à combustion interne.
