摘要： A pumping system for supplying high pressure actuation fluid to individual fuel injectors of an engine equipped with a hydraulically-actuated fuel injection system wherein the three major elements of the system, namely, the pump, the rail pressure control valve and the bleed-off sump or reservoir are physically separated and spaced from one another. The pump is annular, having a central opening through which the engine crankshaft passes. The crankshaft and pump wobble plate are rotationally coupled by opposing flats on each. The pump, rail pressure control valve and reservoir are mounted directly to the engine, receiving and discharging fluid through internal engine passageways, thereby eliminating the usual tubing, and fittings. The pump itself is compact and relatively short in the axial direction, leaving space for mounting such things as a cylindrical housing having belt grooves in its outer surface and a viscous damper on the crankshaft between the pump and the terminal crankshaft end.
摘要翻译：一种用于向配备有液压致动燃料喷射系统的发动机的单个燃料喷射器供应高压致动流体的泵送系统，其中系统的三个主要元件，即泵，轨道压力控制阀和泄放池或储存器在物理上彼此分离和间隔开。泵是环形的，具有发动机曲轴通过的中心开口。曲轴和泵摆动板通过相对的平面旋转耦合。泵，导轨压力控制阀和储存器直接安装在发动机上，通过内部发动机通道接收和排出流体，从而消除了通常的管道和配件。泵本身紧凑并且在轴向方向上相对较短，留下用于安装诸如其外表面中具有带槽的圆柱形壳体和在泵与端子曲轴端之间的曲轴上的粘性阻尼器的空间。

摘要： A control valve assembly adapted for a fuel injector includes a valve seat with fluid inlet and fluid outlet. A poppet valve controls the flow of fluid through the valve seat. A pair of electrical actuators are selectively operably energized for releasing the poppet and moving the poppet to valve open and closed positions. Split fuel injection can be provided using either sequential operation or concurrent operation, i.e., phasing. Permanent magnets, holding current and residual magnetism enable the latching of the poppet valve in each of the valve open and closed positions.

摘要： A dual fuel common rail engine supplies pressurized natural gas and liquid diesel fuel at different pressures through a co-axial quill assembly for direct injection from a single fuel injector into an engine cylinder. Each coaxial quill assembly includes a matched pair of inner and outer quills that are chosen to have dimensions that allow both quills to sealingly engage each fuel injector at a common conical seat responsive to a clamping force applied along an axis. Matched pairs of inner and outer quills are retained together during pre-installation handling with a retainer that is left between the inner and outer quills after installation in an engine.
