Abstract: A fuel injection pump having a cam drive and an injection adjuster piston, acting on the cam drive and serving the purpose of an injection onset adjustment. The injection adjuster piston on a face end encloses at least one pressure chamber that via a control valve is either made to communicate with a pressure source or a relief line or can be closed entirely. The control valve is actuated by an a proportional electromagnet. As a result, only a little adjusting medium is required, to obtain a high efficiency of the injection onset adjustment, and advantageously the injection adjuster piston is stressed only axially, and frictional forces on the circumference of the injection adjuster piston are thus avoided.

Abstract: A fuel injection pump of the distributor type which has a reciprocatingly driven pump piston that is load-bearing in a rotating distributor shaft which pumps fuel out of a pump work chamber to various fuel injection valves via a distributor opening. To control the duration of high-pressure injection, an electrically actuated valve is provided with a valve member in a valve chamber that communicates with the pump work chamber and from a second valve chamber, communicates with a low-pressure region. To terminate the high-pressure injection, the valve member makes a communication between the two valve chambers, whereupon the outflow of the fuel stream is controlled by disposing a diameter constriction in the connecting line, thus reducing any tendency to cavitation.
