Abstract
La présente invention concerne une installation d'injection de carburant. Cette installation comprend un tube d'aspiration 1 contenant un papillon 2 et un organe de mesure 3 monté pivotant et agissant sur le piston de commande 6 d'une soupape de dosage de carburant 7. Le dosage du carburant s'effectue en fonction des paramètres de fonctionnement à l'aide d'une soupape de réglage de pression différentielle 20 qui est séparée en deux chambres 22, 23 reliées l'une à l'autre au moins par l'intermédiaire d'un by-pass 44, 45,46, 47, 48 dont la section est réglable en fonction des différents paramètres de fonctionnement du moteur. L'invention s'applique au moteur à combustion interne des véhicules.
