Abstract

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.
