Abstract

APPAREIL DE POMPAGE DE CARBURANT POUR L'ALIMENTATION D'UN MOTEUR A COMBUSTION INTERNE, COMPRENANT UN ELEMENT 19 A COMMANDE MANUELLE QUI DETERMINE LA VITESSE A LAQUELLE UN REGULATEUR AGIT POUR REDUIRE LA QUANTITE DE CARBURANT FOURNIE PAR L'APPAREIL AU MOTEUR ASSOCIE. UN DISPOSITIF DE BUTEE 21 EST PREVU POUR LIMITER LA COURSE DE DEPLACEMENT DUDIT ELEMENT DANS LE SENS D'UNE AUGMENTATION DE LA VITESSE, CE DISPOSITIF COMPRENANT UN PISTON 33 A DEPLACEMENT AXIAL, UN SOLENOIDE 34 POUR DEPLACER LE PISTON ENTRE UNE POSITION DE TRAVAIL ET UNE POSITION DE REPOS ET UN ORGANE DE BUTEE 32 QUI SERT A LIMITER LA COURSE DE L'ELEMENT A COMMANDE MANUELLE. IL EST PREVU EN OUTRE UN MOYEN DE VERROUILLAGE 36 QUI, LORSQUE LE PISTON EST EN POSITION DE TRAVAIL, MAINTIENT L'ORGANE DE BUTEE 32 DANS UNE PREMIERE POSITION CONTRE L'ACTION DE L'ELEMENT A COMMANDE MANUELLE.FUEL PUMPING APPARATUS FOR SUPPLYING AN INTERNAL COMBUSTION ENGINE, INCLUDING A MANUALLY CONTROLLED ELEMENT 19 WHICH DETERMINES THE SPEED AT WHICH A REGULATOR ACTS TO REDUCE THE QUANTITY OF FUEL SUPPLIED BY THE APPARATUS TO THE ASSOCIATED MOTOR. A STOP DEVICE 21 IS PROVIDED FOR LIMITING THE DISPLACEMENT STROKE OF THE SAID ELEMENT IN THE DIRECTION OF A SPEED INCREASE, THIS DEVICE INCLUDING A PISTON 33 WITH AXIAL DISPLACEMENT, A SOLENOID 34 FOR MOVING THE PISTON BETWEEN A WORKING POSITION AND A REST POSITION AND A STOPPER 32 WHICH SERVES TO LIMIT THE STROKE OF THE MANUALLY CONTROLLED ELEMENT. LOCKING MEANS 36 ARE FURTHER PROVIDED FOR WHICH, WHEN THE PISTON IS IN THE WORKING POSITION, KEEP THE STOPPER 32 IN A FIRST POSITION AGAINST THE ACTION OF THE MANUALLY CONTROLLED ELEMENT.
