ABSTRACT:
A feed pump having a pair of gears in a housing that mesh with each other and are driven to rotate in a pump chamber. The pair of gears supply fuel from an intake chamber connected to a storage tank, along a supply conduit in the housing constituted between the end face of the gears and the circumference wall of the pump chamber, and into a pressure chamber. In order to introduce lateral forces acting on the gears directly into the pump housing the gears are each supported on a housing pin, which is embodied as being of one piece with the housing of the feed pump and protrudes into the housing.
