Abstract
A fuel injection pump volatiling fuel which has an inlet opening to a pump chamber, an impeller in the pump chamber and a side channel, at whose end an outlet opening is provided. The outlet opening is separated from the beginning of the side channel by a sealing surface having a vent hole. To improve the supply properties of fuel with higher temperature the outlet opening has two areas extending across finite angles which are adjacent to each other in the circumferential direction. The areas have radially differing widths and extend farther into the sealing surface with the narrower area externally than internally. The supply quantity of fuel with a higher temperature is accordingly increased.
