Abstract

L'INVENTION A POUR OBJET UN DISPOSITIF D'INJECTION DE CARBURANT POUR MOTEUR A COMBUSTION INTERNE. IL COMPREND UNE CHAMBRE DE RESERVE H, DANS LAQUELLE LE CARBURANT EST MAINTENU SOUS UNE PRESSION CONSTAMMENT ELEVEE, ET DE LAQUELLE IL EST AMENE, EN QUANTITE DOSEE, AUX CYLINDRES PAR DES INJECTEURS E, DONT LES POINTEAUX E SONT LEVES CYCLIQUEMENT, POUR PERMETTRE L'INJECTION DE CARBURANT ALIMENTANT LA CHAMBRE E D'INJECTEUR PAR LE TUYAU H, RELIANT CE DERNIER A LA RESERVE H, ET SUR LEQUEL EST DISPOSE UN DISPOSITIF DE SURETE S MUNI D'UN ORGANE D'ISOLEMENT EMPECHANT LA RESERVE H DE SE VIDER ET LE CARBURANT DE SORTIR DE L'INJECTEUR E, DE FACON INCONTROLEE, LORSQUE LE POINTEAU E, DE FACON INCONTROLEE, LORSQUE LE POINTEAU E RESTE BLOQUE EN POSITION LEVEE. APPLICATION AUX MOTEURS A COMBUSTION INTERNE.THE OBJECT OF THE INVENTION IS A FUEL INJECTION DEVICE FOR INTERNAL COMBUSTION ENGINES. IT INCLUDES A RESERVE CHAMBER H, IN WHICH THE FUEL IS KEPT UNDER CONSTANTLY HIGH PRESSURE, AND FROM WHICH IT IS SUPPLIED, IN DOSED QUANTITY, TO THE CYLINDERS BY INJECTORS E, WHOSE POINTS E ARE CYCLICALLY LIFTED. INJECTION OF FUEL SUPPLYING THE INJECTOR CHAMBER E THROUGH PIPE H, CONNECTING THE LATTER TO THE H RESERVE, AND ON WHICH A SAFETY DEVICE S EQUIPPED WITH AN ISOLATION BODY PREVENTS THE H RESERVE FROM EMPTYING FUEL TO COME OUT OF INJECTOR E, UNCONTROLLED, WHEN NEEDLE E, UNCONTROLLED, WHEN NEEDLE E REMAINS BLOCKED IN THE LIFT POSITION. APPLICATION TO INTERNAL COMBUSTION ENGINES.
