    • A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.
    • 一种用于柴油发动机的燃料喷射泵,其中旋转和往复活塞将燃料加压并分配到通向发动机的喷射阀的各个压力管线。 为了改变相对于发动机循环的喷射时间,提供了一种改变加压活塞与其与发动机同步运行的驱动装置之间的相对角度的机构。 该机构液压操作并受到注射泵的油槽中的燃料压力的影响。 还提供了一种液压控制阀机构,其允许不同量的燃料从燃料输送泵的贮槽向低压侧回流,由此改变喷射正时。 主控制阀基于发动机转速来调节油底壳压力,而二次调节阀根据发动机温度来调节油底壳压力,以便使燃料喷射的时间适应于发动机起动和发动机预热。 呈现各种实施例。
