Abstract
A fuel pump comprising a plunger member reciprocable within a plunger bore, wherein the plunger member is cooperable with a drive arrangement to cause inward movement of the plunger member within the plunger bore to increase fuel pressure therein. The pump comprises an accumulator for fuel, and a valve arrangement controlling communication between the plunger bore and the accumulator to permit fuel under pressure to flow into the accumulator. The pumping plunger is moved in an outward direction under the action of the fuel pressure within the accumulator. The invention also relates to a fuel injection system comprising the fuel pump.
