Abstract
A fuel pumping apparatus for supplying fuel to an internal combustion engine has a drive shaft which is coupled to a rotary part of a high pressure pump. A low pressure pump for supplying fuel to the high pressure pump has a rotor mounted about the drive shaft, a stator and side plates on opposite sides of the stator. The stator has an internal surface engaged by vanes carried by the rotor and one end plate has an arcuate outlet port which is connected to a transfer port formed in the side plate but inwardly of the outlet port. The transfer port is connected by passage means in the rotor with a fuel supply passage in the drive shaft.
