Abstract:
A fuel injection pump includes a pumping section that is segregated from the drive mechanism to permit independent lubrication of the latter, thereby avoiding any need for reliance upon the fuel supplied for that purpose. Generally, the unit will have two pumping stages, one utilizing a rotating vane arrangement and the second comprising reciprocating pistons, and it may include novel means for adjusting timing and speed, which means may automatically be controlled in response to fuel pressure.
