Abstract

LA PRESENTE INVENTION CONCERNE UN INJECTEUR DE COMBUSTIBLE POUR MOTEURS A COMBUSTION INTERNE. IL COMPORTE UNE AIGUILLE D'INJECTEUR LOGEE DANS LE CORPS D'INJECTEUR ET POUVANT COULISSER AXIALEMENT, CETTE AIGUILLE ETANT EQUIPEE, DU COTE DE LA CHAMBRE DE COMBUSTION, D'UN TETON D'ETRANGLEMENT 4 COULISSANT DANS UN ALESAGE CENTRAL 5 DU CORPS D'INJECTEUR. L'INJECTEUR SE CARACTERISE PAR UNE FENTE ANNULAIRE 6 PREVUE ENTRE L'ALESAGE 5 ET LE TETON 4, EN CE QU'UN TROU TRANSVERSAL 9 DEBOUCHE DANS L'ALESAGE CENTRAL 5 ET RELIE LA CHAMBRE DE REFOULEMENT 7 A L'ALESAGE LONGITUDINAL 8, ET EN CE QUE LE TETON 4 PLONGE DANS L'ALESAGE CENTRAL 5 SUR PRESQUE TOUTE SA LONGUEUR.THE PRESENT INVENTION CONCERNS A FUEL INJECTOR FOR INTERNAL COMBUSTION ENGINES. IT INCLUDES AN INJECTOR NEEDLE LOCATED IN THE INJECTOR BODY AND CAN SLIDE AXIALLY, THIS NEEDLE BEING EQUIPPED, ON THE COMBUSTION CHAMBER SIDE, WITH A CHANGING BOTTLE 4 SLIDING IN A CENTRAL BORE 5 OF THE BODY BODY INJECTOR. THE INJECTOR IS CHARACTERIZED BY AN ANNULAR SLOT 6 PROVIDED BETWEEN THE BALEAGE 5 AND THE BORE 4, IN THAT A TRANSVERSAL HOLE 9 OPENS IN THE CENTRAL BALE 5 AND CONNECTS THE DISCHARGE CHAMBER 7 TO THE LONGITUDINAL BORE 8, AND IN THAT TETON 4 DIVES IN CENTRAL BALEAGE 5 ALMOST OF ITS LENGTH.
