<p>A transfer pump for use with a high pressure pump having a rotary drive member (10) and a stationary part (16), comprises a plurality of pumping elements (26) reciprocable within bores (24) provided in the drive member (10), the bores (24) extending generally parallel to the axis of rotation of the drive member (10), the pumping elements (26) being reciprocable under the influence of a cam surface (28) defined by a surface of the stationary part (16) of the high pressure pump, the pumping elements (26) being biased towards the cam surface (28), and valve means associated with the bores (24) controlling the flow of the fuel to and from the bores (24). <IMAGE></p> |
