Abstract

Die Erfindung betrifft eine Kraftstoff-Förderpumpe für eine Kraftstoffeinspritzpumpe (1) für Brennkraftmaschinen, mit zwei in einer Pumpkammer (19) miteinander in Eingriff befindlichen rotierenden Zahnrädern (15, 16), die Kraftstoff aus einem mit einem Vorratsraum verbundenen Ansaugraum entlang einem zwischen den Stirnflächen der Zahnräder (15, 16) und der Umfangswand der Pumpkammer (19) gebildeten Förderkanal in einen mit der Kraftstoffeinspritzpumpe (1) verbundenen Druckraum fördern, wobei eines (15) der Zahnräder (15, 16) durch eine Antriebswelle (12) angetrieben ist.The invention relates to a fuel feed pump for a Fuel injection pump (1) for internal combustion engines, with two in a pump chamber (19) with each other located rotating gears (15, 16), the Fuel from one connected to a pantry Intake space along one between the end faces of the Gears (15, 16) and the peripheral wall of the pump chamber (19) formed delivery channel in one with the Promote the fuel injection pump (1) connected pressure chamber, one (15) of the gears (15, 16) by a Drive shaft (12) is driven.

Um die Verwendung in einem Baukastenprinzip für verschiedene Anwendungen zu ermöglichen, ist die Antriebswelle (12) mit einem Übersetzungsgetriebe (8, 13) gekoppelt.To use in a modular principle for to enable different applications is the Drive shaft (12) with a transmission gear (8, 13) coupled.

In einer Brennkraftmaschine ist die Antriebswelle (12) der Kraftstoff-Förderpumpe (2) zentrisch oder exzentrisch zu der Nockenwelle (7) der Kraftstoff-Einspritzpumpe (1) angeordnet.
