Abstract

A fuel injection pump in which a pump work chamber can be connected with a fuel withdrawal chamber, which is controlled by a deflecting piston. The deflecting piston is loaded by the pressure of the pump work chamber and is adjustable counter to a restoring force, this restoring force being modified with pressure fluid in accordance with rpm.
