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.
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.
Die Vorrichtung ist für eine Brennkraftmaschine eines Fahrzeugs vorgesehen.
