Abstract

L'invention concerne un dispositif d'alimentation en carburant. Selon l'invention, il comporte un dispositif 4 de détection du débit d'air pour générer des signaux électriques à des fréquences proportionnelles au débit d'air d'aspiration; des vannes électromagnétiques 8, 8' ayant des sections différentes de passage du carburant à une jonction 9a d'un collecteur d'aspiration 9; un régulateur 10 de la pression du carburant pour maintenir une différence fixe entre l'alimentation vers les vannes et l'aspiration vers une sortie de carburant; et un moyen de contrôle électrique 7 pour n'entraîner que les vannes de plus petite section quand le moteur fonctionne dans une gamme où le dispositif 4 génère des signaux à de basses fréquences, et au moins les vannes électromagnétiques de plus grande section en synchronisme avec une fréquence produite en démultipliant celle des signaux, quand le moteur fonctionne dans une gamme où le dispositif 4 génère des signaux à des fréquences supérieures. L'invention s'applique notamment à l'industrie automobile.
