Abstract

Eine Brennstoffpumpe (1), die insbesondere als Pumpenanordnung für Brennstoffeinspritzanlagen von luftverdichtenden selbstzündenden Brennkraftmaschinen dient, weist zumindest ein Gehäuseteil (3), ein erstes Zahnrad (15) und ein zweites Zahnrad (16) auf. Dabei sind die Zahnräder (15, 16) in dem Gehäuseteil (3) angeordnet. Ferner kämmen die Zahnräder (15, 16) miteinander, um eine Zahnradpumpe (17) auszubilden. Ferner ist ein Zu- oder Rücklauf (35, 36) für die Zahnradpumpe (17) vorgesehen, der in dem Gehäuseteil (3) vorgesehen ist.
