Abstract

Die Erfindung betrifft eine Kraftstofffördereinheit 1 mit einem in einen Kraftstoffbehälter 2 eines Kraftfahrzeugs anzuordnenden Schwalltopf 3, in dem eine zur Förderung von Kraftstoff zu einer Brennkraftmaschine vorgesehene Kraftstoffpumpe 4 angeordnet ist, mit einer Saugstrahlpumpe 6 zur Förderung von Kraftstoff aus dem Kraftstoffbehälter 1 in den Schwalltopf 3, wobei die Saugstrahlpumpe 6 ein Gehäuse 8 besitzt, das mindestens einen ersten Kanal 19 zum Zuführen von Kraftstoff als Treibmittel zu einer Treibstrahldüse 25 der Saugstrahlpumpe 6, und mindestens einen zweiten Kanal 10 zum Zuführen von Kraftstoff aus dem Schwalltopf 3 zu einem Einlasskanal 5 der Kraftstoffpumpe 4 aufweist. Das Gehäuse 8 weist einen senkrecht zur Längsachse 22 eines Mischrohres 21 der Saugstrahlpumpe 6 angeordneten und einteilig mit dem Gehäuse 8 verbundenen Rahmen 12 auf, dessen umrahmte Fläche 17 mit Filtergewebe 15, 16 bedeckt ist, indem das Filtergewebe 15, 16 auf beiden Seiten 13, 14 des Rahmens 12 angeordnet ist, um so einen Filter 7 zu bilden, und dass der Rahmen 12 in seinem der Saugstrahlpumpe 6 zugewandte Bereich eine zwischen dem Filtergewebe 15, 16 angeordnete Öffnung 11 besitzt, welche in den mindestens zweiten Kanal 10 übergeht.
