Abstract: A fuel pump comprising a first pumping plunger reciprocable within a first bore and defining, with the first bore, a first pumping chamber. A second pumping plunger is reciprocable within a second bore and defines, with the second bore, a second pumping chamber. The fuel pump further comprises a supply passage, whereby fuel from the first pumping chamber is supplied to the second pumping chamber. A drive arrangement is provided for driving the first and second pumping plungers in both an extending direction and a retracting direction such that when the drive arrangement drives the first pumping plunger in its retracting direction, the second pumping plunger is driven in its extending direction to expel fuel from the second pumping chamber, and when the drive arrangement drives the first pumping plunger in its extending direction, the second pumping plunger is driven in its retracting direction and fuel is expelled from the first pumping chamber through the supply passage to the second pumping chamber.

Abstract: A fuel supply apparatus for supplying fuel to a compression ignition engine comprising a rotary distributor member having a delivery passage which can register in turn with outlet ports connected to the injection nozzles of the engine. Fuel is supplied to the delivery passage from an accumulator under the control of a valve. The accumulator is charged with fuel by means of a high pressure pump which is a cam actuated pump and fuel is supplied to the high pressure pump by a low pressure pump. A valve is provided to control the output pressure of the low pressure pump so that the amount of fuel supplied to the high pressure pump can be varied for the purpose of controlling the fuel pressure within the accumulator. This pressure is sensed by a transducer which supplies a signal to a control system which controls the flow of electric current in the valve.
Abstract translation: 一种用于向压缩点火发动机供应燃料的燃料供应装置，包括具有输送通道的旋转分配器构件，该输送通道可依次与所述发动机的喷嘴连接的出口连接。 在阀门的控制下，燃料从蓄能器供给到输送通道。 蓄能器通过作为凸轮驱动的泵的高压泵对燃料充电，并且通过低压泵将燃料供应到高压泵。 提供一个阀门来控制低压泵的输出压力，从而为了控制蓄能器内的燃料压力，可以改变供给高压泵的燃油量。 该压力由向控制系统中的信号提供的换能器感测，控制系统控制阀中的电流。

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.
