Abstract

Die Kraftstoffeinspritzeinrichtung weist einen Kraftstoffspeicher (16), eine Kraftstoffhochdruckpumpe (14), durch die Kraftstoff abhängig von Betriebsparametern der Brennkraftmaschine in den Kraftstoffspeicher (16) gefördert wird, eine Vorförderpumpe (12), durch die Kraftstoff aus einem Kraftstoffvorratsbehälter (10) zur Saugseite der Kraftstoffhochdruckpumpe (14) gefördert wird, eine Kraftstoffzumeßeinrichtung (44) zur Einstellung der durch die Kraftstoffhochdruckpumpe (14) in den Kraftstoffspeicher (16) geförderten Kraftstoffmenge, und wenigstens einen mit dem Kraftstoffspeicher (16) verbundenen Injektor (20) zur Kraftstoffeinspritzung an der Brennkraftmaschine auf. Die Zumeßeinrichtung (44) ist zwischen dem Kraftstoffvorratsbehälter (10) und der Saugseite der Vorförderpumpe (12) angeordnet. Die Kraftstoffhochdruckpumpe (14) weist einen Antriebsbereich (32) auf, der zu dessen Schmierung mit dem Auslaß der Vorförderpumpe (12) über ein zum Antriebsbereich (32) hin öffnendes Druckventil (48) verbindbar ist.

Figure 00000001
The fuel injection device has a fuel reservoir (16), a high-pressure fuel pump (14), through which fuel is conveyed into the fuel reservoir (16) depending on operating parameters of the internal combustion engine, a pre-feed pump (12), through which fuel from a fuel reservoir (10) to the suction side of the High-pressure fuel pump (14) is conveyed, a fuel metering device (44) for setting the amount of fuel delivered by the high-pressure fuel pump (14) into the fuel accumulator (16), and at least one injector (20) connected to the fuel accumulator (16) for fuel injection on the internal combustion engine , The metering device (44) is arranged between the fuel reservoir (10) and the suction side of the prefeed pump (12). The high-pressure fuel pump (14) has a drive area (32) which, for its lubrication, can be connected to the outlet of the pre-feed pump (12) via a pressure valve (48) opening towards the drive area (32).
