FUEL INJECTION NOZZLE FOR INTERNAL COMBUSTION ENGINES

Abstract

Abstract Translated from French A.L'INVENTION CONCERNE UNE BUSE D'INJECTION DE CARBURANT POUR MOTEURS A COMBUSTION INTERNE, COMPORTANT UN POINTEAU DE SOUPAPE S'OUVRANT DANS LE SENS OPPOSE A CELUI DU COURANT DE CARBURANT ET SUR LEQUEL EST MONTE UN PISTON QUI, RELIE A UN CANAL SERVANT A LA CONDUITE DE CARBURANT, EST GUIDE, DE FACON ETANCHE RADIALEMENT, DANS UN CORPS D'INJECTION DANS LA ZONE DE LA SORTIE DU CARBURANT, UNE OUVERTURE DE COMMANDE ASSURANT LA MISE EN ACTION D'AU MOINS UN ORIFICE D'INJECTION LORS DU MOUVEMENT DE LEVAGE DU PISTON. B.CETTE BUSE EST CARACTERISEE EN CE QUE L'ORIFICE D'INJECTION EST MENAGE DANS LE POINTEAU DE LA SOUPAPE ET L'OUVERTURE ASSURANT L'INJECTION EST MENAGEE DANS LE CORPS D'INJECTION. C.L'INVENTION EST APPLICABLE A L'ALIMENTATION EN CARBURANT DES MOTEURS A COMBUSTION INTERNE. A. THE INVENTION RELATES TO A FUEL INJECTION NOZZLE FOR INTERNAL COMBUSTION ENGINES, INCLUDING A VALVE NEEDLE OPENING IN THE DIRECTION OPPOSITE TO THAT OF THE FUEL CURRENT AND ON WHICH IS MOUNTED A PISTON WHICH, CONNECTED TO A CHANNEL SERVED FOR THE FUEL LINE, IS GUIDED, IN A RADIALLY SEALED MANNER, IN AN INJECTION BODY IN THE FUEL OUTLET ZONE, A CONTROL OPENING ENSURING THE ACTION OF AT LEAST ONE INJECTION PORT DURING THE PISTON LIFTING MOVEMENT. B. THIS NOZZLE IS CHARACTERIZED IN THAT THE INJECTION PORT IS CONTAINED IN THE NEEDLE OF THE VALVE AND THE OPENING ENSURING THE INJECTION IS PROVIDED IN THE INJECTION BODY. C. THE INVENTION IS APPLICABLE TO THE FUEL SUPPLY OF INTERNAL COMBUSTION ENGINES.
