Abstract

a. L'invention concerne une pompe d'injection de carburant comportant au moins un piston de pompage actionné par une commande par cames et un régulateur d'injection décalant la position des cames par rapport à l'arbre d'entraînement, des organes de commande agissant sur la liaison entre la chambre de pompage et une chambre de carburant à basse pression, le déroulement de la commande par rapport aux cames variant avec le décalage d'injection. b. Cette pompe est caractérisée en ce qu'un dispositif de synchronisation maintient le déroulement relatif de la commande en cas de décalage d'injection. c. L'invention est applicable à l'alimentation des moteurs à combustion interne.
