Abstract

Förderpumpe mit einem in einer Pumpkammer rotierend angetriebenen Paar miteinander kämmender Zahnräder (5,9), die vorzugsweise Kraftstoff aus einem mit einem Vorratstank verbundenen Ansaugraum entlang einem zwischen der Stirnfläche der Zahnräder (5,9) und der Umfangswand der Pumpkammer gebildeten Förderkanal in einen Druckraum fördern.
Um dabei die an den Zahnrädern (5,9) auftretenden Querkräfte direkt in das Pumpengehäuse (1) einzuleiten, sind die Zahnräder (5,9) jeweils auf einem in das Gehäuse (1) der Förderpumpe ragenden, einteilig mit dem Gehäuse (1) ausgebildeten Gehäusezapfen (23,25) gelagert.

Figure 00000001
Feed pump with a pair of meshing gear wheels (5,9) driven in rotation in a pump chamber, which preferably fuel into a pressure chamber from a suction chamber connected to a storage tank along a delivery channel formed between the end face of the gear wheels (5,9) and the peripheral wall of the pump chamber promote.
In order to introduce the transverse forces occurring on the gearwheels (5,9) directly into the pump housing (1), the gearwheels (5,9) are each mounted on one piece with the housing (1) protruding into the housing (1) of the feed pump. trained housing pin (23.25) stored.
