Abstract

Die Erfindung betrifft eine Einrichtung zum Fördern von Kraftstoff zu einem Verbrennungsmotor mittels einer Förderpumpe 1 für Einspritzanlagen, die als vorzugsweise direkt aus dem Kraftstofftank 5 fördernde und direkt vom Verbrennungsmotor angetriebene Zahnrad- oder Flügelzellenpumpe ausgeführt ist und mit einem Speichertopf 3 zusammenwirkt.
Die Aufgabe der Erfindung besteht darin, eine gattungsgemäße Kraftstofförderpumpe hinsichtlich ihres Saugverhaltens nach dem Leerfahren des Kraftstomanks zu verbessern.
Erfindungsgemäß ist der Förderpumpe 1 druckseitig ein Speichertopf 3 nachgeschaltet, wobei eine Kraftstoffzulaufleitung 2 a bzw. Kraftstoffzulaufleitungen oberhalb der Förderpumpe 1 am Speichertopf 3 angeschlossen ist bzw. sind.
Der Speichertopf 3 überdeckt axial den Bereich der Förderpumpe 1 und einen Teil der anliegenden Dichtgrenzen. Ein Druckbegrenzungsventil 11 ist vorzugsweise an der höchsten Stelle des Speichertopfes 3 angeschlossen und über eine Kraftstoffrückleitung 12 mit der Saugseite der Förderpumpe 1 verbunden.
In der Saugleitung 6 der Förderpumpe 1 ist ein den Rücklauf verhinderndes Rückschlagventil 7 angeordnet.
