Abstract
The invention relates to a fuel feed pump for a fuel injection pump for internal combustion engines, having a pair of gear wheels that mesh with one another and are driven to rotate in a pump chamber. The pair of gear wheels pump fuel out of an intake chamber that communicates with a supply tank along a feed conduit, formed between the end face of the gear wheels and the circumferential wall of the pump chamber, into a pressure chamber that communicates with the fuel injection pump. One gear wheel is secured to a shaft is driven to rotate by means of a drive element that engages the shaft, wherein the drive element can be connected to the shaft by an overload safety device.
