Abstract

L'INVENTION CONCERNE UN INJECTEUR DE CARBURANT POUR MOTEUR A COMBUSTION INTERNE, A INJECTION ET A COMPRESSION D'AIR, EQUIPE D'UNE AIGUILLE VENANT EN POSITION D'OUVERTURE, DECOLLANT DE SON SIEGE DE FORME CONIQUE, DANS UN PORTE-INJECTEUR, DANS LE SENS OPPOSE A CELUI DE L'ECOULEMENT DU CARBURANT, EQUIPE PAR AILLEURS D'UN CANAL DE SORTIE SE RACCORDANT AU SIEGE ET NE POUVANT ETRE OBTURE DU COTE PAR LEQUEL IL DEBOUCHE DANS LA CHAMBRE DE COMBUSTION. DANS LE SENS D'ECOULEMENT, LA PAROI DU CANAL DE SORTIE 4 COMPREND AU MOINS UNE ZONE DE DISCONTINUITE ETOU UNE ZONE EVASEE PROVOQUANT UN DECOLLEMENT DE L'ECOULEMENT. POUR RENDRE LE FONCTIONNEMENT DES INJECTEURS DE CARBURANT MOINS SUJET AUX DERANGEMENTS, L'INVENTION A POUR BUT D'EVITER LE CALAMINAGE DE L'ORIFICE DE SORTIE.
