    • In a two-stage fuel pump (14) liquid fuel passes via gear pump (24) and radial piston pump (28) to two similar metering fuel distributors (32), (34). Delivery from piston pump (28) is variable by means of an eccentric piston drive arrangement such that maximum delivery occurs under reduced speed conditions, such as engine cranking or heavy load. Distribution (32), (34) comprise hollow cylindrical members (230) in which rotate spindles (234) driven from gear pump (24). The spindles (234) have cavities (300), (302) which periodically align with an arrangement of ports through the walls of members (230). As spindles (234) rotate, fuel is alternately received into and delivered from cavities (300), (302) metering and delivery being effected by a slidable pin (304) which axially reciprocates through spindle (234) to intrude a controllable variable amount into cavities (300), (302) under alternately applied fuel pressure to effect variable fuel displacement. Provision is made for varying the timing of fuel displacement by variation of the angular displacement of the spindle (234) of the distributor (32) relative to its drive shaft (90) from the gear pump (24).

    • A fuel injection control device comprising a timing body (5) rotating between surfaces of two normally stationary bodies (4 and 6), each body having periodically alignable fluid conduit means to time, meter and distribute pressurized fluid pulses to injectors of an internal combustion engine. The volume of each fluid pulse is controlled by turning one of the normally stationary bodies (4) to adjust the overlap alignment between respective openings of the normally stationary bodies. Cam actuated piston pumping means are utilized for higher pressure fuel injection. Rotating cam actuated piston pumping means are disposed in removable plunger cartridges.
    • 一种燃料喷射控制装置,包括在两个正常静止体(4和6)的表面之间旋转的定时体(5),每个主体具有周期性可对准的流体管道装置,以将加压流体脉冲时间,计量和分配到内燃机的喷射器 。 通过转动正常静止体(4)中的一个来调节每个流体脉冲的体积,以调节正常静止体的相应开口之间的重叠对准。 凸轮致动的活塞泵送装置用于更高压力的燃料喷射。 旋转凸轮致动的活塞泵送装置设置在可拆卸的柱塞盒中。
