Abstract

Bei Kraftstoffversorgungsanlagen mit zwei in Reihe geschalteten Pumpen und direkt in den Brennraum einspritzenden Kraftstoffventilen gab es bei höheren Temperaturen bisher häufig Probleme wegen ungenügender Förderwirkung der zweiten Kraftstoffpumpe.For fuel supply systems with two in series Pump and inject directly into the combustion chamber There have been fuel valves at higher temperatures so far often problems due to insufficient funding from the second Fuel pump.

Es wird nun vorgeschlagen, ein Absperrventil (30), das bei höherer Temperatur geschlossen wird, und eine Spülleitung (60), durch die bei höherer Temperatur Kraftstoff zum Kraftstoffvorratsbehälter (2) geleitet wird, vorzusehen. Damit soll möglichst viel Wärmeenergie aus der zweiten Kraftstoffpumpe (12) abgeführt und durch einen höheren Speisedruck soll der Bildung von Gasblasen entgegengewirkt werden.It is now proposed to use a shut-off valve (30) higher temperature is closed, and a flushing line (60) through which fuel is delivered to the fuel tank at a higher temperature (2) is to be provided. In order to should have as much thermal energy as possible from the second fuel pump (12) dissipated and by a higher feed pressure the formation of gas bubbles is to be counteracted.

Die Vorrichtung ist für eine Brennkraftmaschine eines Fahrzeugs vorgesehen.
