Abstract (en)

The pump has at least two pump elements (3) for delivering fuel into a high-pressure connection (25) and at least one controlable hydraulic connection (29) between two pump elements. The hydraulic connection is controled by at least one control valve, especially a 2/2-way valve. Several control valves can be arranged in parallel and operated by an actuator, especially an electromagnetic actuator or a piezoelectric actuator.

Abstract (de)

Es wird eine Kraftstoffhochdruckpumpe (1) vorgeschlagen, bei der durch einen Druckausgleich zwischen den Pumpenelementen (3) eine Regelung der Fördermenge stufenlos zwischen 0 und 100 % erfolgen kann. <IMAGE>
