ABSTRACT:
A fuel injection pump, embodied as a series pump, has a governor rod for rotating a pump piston provided with an oblique control groove. The pump piston further has at least one longitudinal groove, by means of which upon congruence with a fill and relief opening of the pump work chamber, a zero fuel supply can be established. With electrically controlled actuation of the governor rod, the appropriate adjustment of the end stops of the governor rod or the appropriate embodiment of the pump piston assures that the opening comes into congruence with a longitudinal groove adjoining the full-load working zone of the pump piston before the end stop of the governor rod is reached.
