Abstract

La présente invention concerne une soupape de dosage de carburant pour un système d'injection de carburant. Cette soupape disposée sur le tube d'aspiration d'un moteur comprend un piston de commande 3 monté tournant à l'intérieur d'un cylindre 4. Le piston 3 est monté entre deux emplacements de logement 13 et 14 qui servent également de logement à un organe de mesure de la quantité d'air suivant laquelle le piston est déplacé. Une rainure hélicoïdale 19 du piston 3 forme avec la paroi extérieure dudit piston une arête de commande 20. Pour régulariser l'écoulement du carburant et réduire le frottement du piston contre la paroi interne du cylindre 4, on a prévu sur les surfaces périphériques des emplacements de logement 13 et 14, des rainures également périphériques 27. L'invention s'applique aux moteurs à combustion interne des véhicules.The present invention relates to a fuel metering valve for a fuel injection system. This valve arranged on the suction tube of an engine comprises a control piston 3 rotatably mounted inside a cylinder 4. The piston 3 is mounted between two housing locations 13 and 14 which also serve as housing for a device for measuring the quantity of air in which the piston is moved. A helical groove 19 of the piston 3 forms with the outer wall of said piston a control edge 20. To regulate the flow of fuel and reduce the friction of the piston against the internal wall of the cylinder 4, locations have been provided on the peripheral surfaces. housing 13 and 14, also peripheral grooves 27. The invention applies to internal combustion engines of vehicles.
