Document Type and Number:
Japanese Patent JP2000513784
Kind Code:
A
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.
