Abstract

Appareil de pompage pour l'alimentation en combustible d'un moteur à combustion interne comprenant un distributeur rotatif 12, une pompe d'injection comprenant des pistons 19 logés dans un alésage transversal 17 et déplaçables vers l'intérieur par une came 20, un conduit 22 par lequel s'écoule le combustible refoulé par les pistons 19 et une pluralité d'orifices de sortie 24 communiquant tour à tour avec le conduit 22. L'appareil comprend en outre une pompe basse pression comportant deux autres pistons 27 montés dans un alésage transversal 18 et une came 28 positionnée de manière que du combustible soit refoulé de l'alésage 18 à l'alésage 17 lorsque le conduit 22 ne communique pas avec un orifice de sortie, un clapet 26 monté dans le conduit, et un moyen pour déterminer la course des pistons 27 correspondant à un envoi de combustible vers l'alésage 17.
