Abstract

L'invention concerne un dispositif d'alimentation en carburant pour un moteur. Selon l'invention, il comprend un dispositif 4 de détection du débit d'air pour générer un signal électrique dont la fréquence est proportionnelle au débit variable d'air d'aspiration; un certain nombre de vannes électromagnétiques 8 disposées à une jonction d'un collecteur d'aspiration 9 pour controler le débit de carburant pour maintenir une différence de pression fixe entre la pression d'alimentation du carburant vers les vannes électromagnétiques et la pression d'aspiration à proximité d'une sortie du carburant; et un moyen de contrôle électrique 7 pour entraîner les vannes électromagnétiques à une phase décalée les unes par rapport aux autres en synchronisme avec une fréquence du signal électrique généré par le dispositif de détection 4. L'invention s'applique notamment à l'industrie automobile.
