Injection pump for an internal-combustion engine comprising a mechanism for controlling the start of the fuel injection delivery
Abstract
Abstract Translated from French Le dispositif de réglage comprend un clapet (13) de fermeture et d'ouverture d'un canal de dérivation (14) susceptible de relier la chambre de pompage (5) à un espace (10) communiquant avec la source de combustible de remplissage de la chambre (5), et un système de commande (17-27) de ce clapet (13) comportant un dispositif de commande pour la fermeture de ce clapet en fonction de la position angulaire d'un organe rotatif (27) du moteur, tel que l'arbre manivelle. The adjustment device comprises a valve (13) for closing and opening a bypass channel (14) capable of connecting the pumping chamber (5) to a space (10) communicating with the source of fuel for filling the the chamber (5), and a control system (17-27) of this valve (13) comprising a control device for closing this valve as a function of the angular position of a rotary member (27) of the motor, such as the crankshaft.
