    Abstract: A liquid fuel injection pump for supplying precisely measured charges of fuel under high prssure, has a housing in which a fuel distributing rotor is journaled. The rotor carries a high pressure charge pump for pressurizing the charges of fuel and a pair of through bores in the housing mount a pair of shuttles which alternate in pumping measured charges of fuel into the charge pump chamber. Fuel regulated by a metering valve is delivered to a chamber at one end of each shuttle and the fuel charge so produced is then pumped into the charge pump chamber by applying hydraulic pressure to the other end of the shuttle. A ball check valve carried by the rotor isolates the shuttles from the charge pump. An axially adjustable stop at each end of each through bore limits the movement of each shuttle in each direction and the stops for each shuttle are accessible through the end of its through bore for changing the limit of movement of the shuttle in each direction independently of the other stop for the shuttle. A passage supplies fuel to a closer plunger which hydraulically seats the ball check valve and the fuel trapped between the plunger and its stop cushions the impact therebetween as the charge pump pressurizes the pressure, in the rotor.

    Abstract translation: 一种液体燃料喷射泵，用于在高精度下提供精确测量的燃料的燃料，具有壳体，燃料分配转子安装在壳体中。 转子承载高压电荷泵，用于加压燃料的电荷和壳体中的一对穿孔，一对穿梭器将泵送测量的燃料进入电荷泵室。 由计量阀调节的燃料被输送到每个梭的一端的腔室中，然后通过向梭子的另一端施加液压将所产生的燃料充入泵送到电荷泵室中。 由转子携带的球形止回阀将来自电荷泵的梭子隔开。 每个通孔的每个端部处的可轴向调节的止动件限制每个梭子在每个方向上的移动，并且每个梭子的止动件可通过其通孔的端部进入，用于改变梭子在每个方向上的移动极限，独立于 其他停靠站的班车。 通道为靠近柱塞提供燃料，该柱塞液压地安置球止回阀，并且随着电荷泵加压转子中的压力，捕获在柱塞和止动垫之间的燃料抵靠其间的冲击。

    Abstract: A liquid fuel injection pump for supplying timed charges of fuel to an engine by timed pumping strokes includes an adjustable timing mechanism for changing the timing of the pumping strokes. The timing mechanism includes an advance piston which is variably positionable in response to two different hydraulic control pressures. A speed related control pressure operates a servo mechanism associated with the advance piston to provide a component of speed advance. The reference position of a servo spring associated with the servo mechanism is varied by the second control pressure acting against a piston which mounts the spring and which is biased to a position of relatively advanced timing, thereby to add a component of advance which modifies or supplements the speed advance. The second control pressure is correlated with engine load and/or acceleration and in one embodiment is derived from the positioning of the fuel metering means and in another embodiment is derived from the intake manifold air pressure such as that from a turbocharged engine so that the timing is relatively advanced at low loads and during acceleration, and is relatively retarded at higher loads. A gate controlled by the position of a fuel limiting plunger coacts with the advance piston's servo mechanism to prevent advance of the advance piston during engine cranking, and maximum fuel delivery per pumping stroke is controlled according to intake manifold air pressure.
