ABSTRACT:
A fuel injection pump in which for the purpose of controlling the injection quantity and in particular to determine the onset and end of injection, a hydraulically actuatable piston slide is provided, which controls a connection between the pump work chamber and a fuel supply line or the fuel supply container. The control is effected via two magnetic valves acting in opposite directions, by means of which two different, high control pressures acting upon the piston slide can be exerted. The control pressures are made available either with a single pressure control valve and by blocking off the relief of the supply side of the fuel supply pump, or else by means of two pressure control valves.
