Abstract

Die Erfindung betrifft eine Kraftstoff-Förderpumpe für eine Kraftstoff-Einspritzpumpe für Brennkraftmaschinen, mit einem in einer Pumpkammer (3) rotierend angetriebenen Paar miteinander kämmender Zahnräder (7, 9), die Kraftstoff aus einem mit einem Vorratstank verbundenen Ansaugraum (13) entlang einem zwischen der Stirnfläche der Zahnräder (7, 9) und der Umfangswand der Pumpkammer (3) gebildeten Förderkanal (17) in einen, mit der Kraftstoff-Einspritzpumpe verbundenen Druckraum (15) fördern, mit einem auf einer Welle (5) befestigten Zahnrad (7), das mittels eines an der Welle (5) angreifenden Antriebselementes (8) rotierend antreibbar ist, wobei das Antriebselement (8) mit einer Überlast-Sicherungsvorrichtung (10) zur Welle (5) verbindbar ist.
