Abstract

La présente invention concerne une installation d'injection de carburant. Cette installation comprend un papillon 2 et un clapet de retenue pivotant 3 monté au bord d'un tube d'aspiration 1. Un prolongement 5 du clapet 3 est muni d'un alésage 6 recevant un piston de commande 8 monté tournant dans un cylindre de commande fixe 9. Le cylindre 9 est monté fixe à côté du clapet de retenue 3 à l'extérieur du tube d'aspiration 1 et le piston de commande rotatif 8 est relié à l'extérieur du cylindre 9 par sa première extrémité 7 au clapet 3 et par son autre extrémité 18 à l'ailette d'amortisseur 17 logé dans la chambre 16 prévue à l'extrémité supérieure du cylindre 9. L'invention s'applique aux moteurs à combustion interne des véhicules.
