Abstract

A.INJECTEUR DE CARBURANT POUR MOTEURS A COMBUSTION INTERNE. B.INJECTEUR DE CARBURANT POUR MOTEURS A COMBUSTION INTERNE COMPORTANT UNE CHAMBRE ANNULAIRE PREVUE EN AVAL DU SIEGE DE SOUPAPE ENTRE LE POINTEAU DE SOUPAPE ET LE CORPS D'INJECTION, AINSI QU'UN ALESAGE BORGNE LONGITUDINAL DEBOUCHANT DU COTE FRONTAL DU POINTEAU DE SOUPAPE, ET QUI EST BRANCHE SUR CETTE CHAMBRE ANNULAIRE PAR UNE LIAISON S'ETENDANT SENSIBLEMENT EN DIRECTION TRANSVERSALE AU POINTEAU ET PRESENTANT UNE PLUS GRANDE SECTION TRANSVERSALE QUE L'ALESAGE BORGNE LONGITUDINAL, INJECTEUR CARACTERISE EN CE QUE, AFIN D'EVITER QUE DE LA LIMAILLE NE SOIT ENTRAINEE, A PARTIR DE LA CHAMBRE ANNULAIRE 9, DANS L'ALESAGE LONGITUDINAL 7, DANS UN SENS DE DIMENSION AU MOINS DE LA LIAISON 8, 10 LE DIMENSIONNEMENT PREVU POUR CELLE-CI EST PLUS PETIT QUE LE DIAMETRE DE L'ALESAGE BORGNE 7.A. FUEL INJECTOR FOR INTERNAL COMBUSTION ENGINES. B. FUEL INJECTOR FOR INTERNAL COMBUSTION ENGINES INCLUDING AN ANNULAR CHAMBER PROVIDED DOWNSTREAM OF THE VALVE SEAT BETWEEN THE VALVE NEEDLE AND THE INJECTION BODY, AS WELL AS A LONGITUDINAL BLOCK BORE OPENING FROM THE POINT FRONT, AND FRONT OF THE POINT, AND FRONT OF THE POINT WHICH IS CONNECTED TO THIS ANNULAR CHAMBER BY A CONNECTION EXTENDING SENSITIVELY CROSS-DIRECTED AT THE NEEDLE AND PRESENTING A LARGER CROSS-SECTION THAN THE LONGITUDINAL BORING BORD, INJECTOR CHARACTERIZED IN THAT, IN ORDER TO AVOID THAT THE STAINED IS , FROM THE ANNULAR CHAMBER 9, IN THE LONGITUDINAL BALE 7, IN A DIMENSIONAL DIRECTION AT LEAST OF LINK 8, 10 THE DIMENSIONING PROVIDED FOR THIS IS SMALLER THAN THE DIAMETER OF THE BORNE 7 BALEAGE.
