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.

Abstract: A fuel pump includes a pumping plunger reciprocable within a bore formed in a pump housing under the influence of a cam drive arrangement. The cam drive arrangement includes a reciprocable tappet member, a surface associated with the tappet member defining, in part, an auxiliary pumping chamber. A flow path interconnects the auxiliary pumping chamber and the bore such that fuel displaced from the auxiliary pumping chamber, in use, can be supplied through the flow path to the bore.

Abstract translation: 燃料泵包括在凸轮驱动装置的影响下在形成于泵壳体中的孔内往复运动的泵送柱塞。 凸轮驱动装置包括往复式挺杆构件，与挺杆构件相关联的表面，其部分地限定辅助泵送室。 流动路径将辅助泵送室和孔相互连接，使得在使用中从辅助泵送室排出的燃料可以通过流路提供给孔。
