Abstract
A fuel injection pump has an injection adjuster whose injection adjuster piston is acted upon on one face end by a restoring spring and by a pressure controlled by a control slide. On another face end the injection adjuster piston is exposed constantly to a pressure fluid source, which furnishes an rpm-dependent pressure. The control slide is adjusted positively by a control piston actuated by a control pressure, and in the process the control piston varies the pressure, acting the one face end, in a closed first pressure chamber. The injection adjuster piston is thus free of relatively high adjusting pressures acting on the injection adjuster piston transversely to a direction of motion.
