摘要： A fuel injector for an internal combustion engine having a crankshaft is disclosed. The fuel injector has plunger to displace fuel and an electronically controlled spill valve. The fuel injector also has a nozzle member having at least one orifice and a valve needle disposed within the nozzle member, and movable against a spring bias to selectively inject pressurized fuel through the at least one orifice. The fuel injector also has an electronically controlled check valve. The valve needle is automatically moved to inject pressurized fuel when the pressure of the fuel within the fuel injector reaches a predetermined valve opening pressure determined by a spring bias. Valve elements of the electronically controlled spill and check valves are both in a flow blocking position before the pressure of the fuel within the fuel injector reaches the predetermined valve opening pressure. Injection terminates when the valve element of the electronically controlled check valve is moved to a flow-passing position.

摘要： A fuel injector includes an injector body having an internal surface and an external surface. A tappet assembly includes a non-guided tappet and a plunger assembly, and is mounted on the injector body. The tappet assembly is movable with respect to the injector body a displacement distance between an advanced position and an extended position. A portion of the plunger assembly is slidably guided along the internal surface of the injector body, while the non-guided tappet is free of contact with both the internal surface and the external surface of the injector body in the advanced and extended positions. The tappet assembly may be prevented from moving beyond the extended position using a snap ring positioned within a retention opening of the fuel injector body.

摘要： A mechanically actuated electronically controlled unit injector includes an electronically controlled spill valve to precisely control timing of fuel pressurization within a fuel pressurization chamber. Cavitation bubbles may be generated in the region of the valve seat when the spill valve member is closed to raise fuel pressure in the fuel injector. This cavitation can cause erosion on the spill valve member and the surrounding injector body. In order to preempt cavitation damage, the valve member may be modified to include a compound annulus that includes a small annulus that corresponds to an identified cavitation damage pattern. Although the generation of cavitation bubbles may continue after such a strategy, cavitation erosion, and the associated liberation of metallic particles into the fuel system can be reduced, and maybe eliminated, by the preemptive cavitation reduction strategy.

摘要： A relatively inexpensive robust attachment strategy that insures good perpendicularity between a valve member and an armature utilizes an intervening nut between the armature and valve member. A valve member is received in a guide bore of a valve body. A nut is threaded onto one end of a valve member. The armature is press fit onto a orientation neutral interface of the nut, and a fixture is utilized to set near perfect perpendicularity between an air gap plane of the armature and a centerline of the valve member. The armature is then welded to the valve member. The weld may be accomplished via laser welding while the valve assembly is firmly held in an appropriate position within the fixture. The valve assembly may be then incorporated into a fuel injector stack of components in a conventional manner.

摘要： A fuel injection system includes a fuel pressurizer that may be cam actuated. The fuel injection system also includes an electronically controlled spill valve and an electronically controlled needle control valve. The energization of the electronically controlled spill valve closes a fuel pressurization chamber to a drain passage to allow fuel pressure in the fuel injector to build to injection levels. The electronically controlled needle control valve controls whether high or low fuel pressure is applied to a closing hydraulic surface associated with a direct control needle valve. The fuel injection system includes a hydraulic circuitry that allows for fuel injection to occur by either maintaining the electronically controlled needle control valve in a de-energized state, or by de-energizing the same, after fuel pressure within the fuel injector has built to injection levels. With a de-energize to inject hydraulic circuitry associated with the direct control needle valve, the fuel injection system can prevent overpressurization in the event of electrical failure in the needle control electronic circuitry. This also provides a fuel engine with a limp home capability in the case of such an electronic problem. In addition, the fuel injection system can have reduced overall power requirements that can lead to downsizing and other cost saving advantages.
摘要翻译：燃料喷射系统包括可以被凸轮致动的燃料加压器。燃料喷射系统还包括电子控制的溢流阀和电子控制的针阀。电子控制溢流阀的通电将燃料加压室关闭到排放通道，以允许燃料喷射器中的燃料压力建立到喷射水平。电子控制针控制阀控制是否对与直接控制针阀相关联的关闭液压表面施加高或低的燃料压力。燃料喷射系统包括液压回路，其允许通过将电子控制的针控制阀保持在断电状态或者通过使燃料喷射器内的燃料压力建立到喷射器之后将燃料喷射器保持在断电状态水平。通过断电来注入与直接控制针阀相关联的液压回路，燃料喷射系统可防止在针控电子电路中出现电气故障时的过压。这也提供了一种在这种电子问题的情况下具有跛足的能力的燃料发动机。此外，燃料喷射系统可以降低总体功率需求，这可以导致小型化和其他成本节省的优点。

摘要： An electromagnetic control valve is provided. The control valve includes a housing defining a bore and a fluid passageway having a seat. A valve element is slidably disposed in the bore and is moveable between a first position where a flow of fluid passes by the seat and a second position where a flow of fluid relative to the seat is blocked. A solenoid having an armature is operatively connected with the valve element. The solenoid is operable to move the valve element from the first position to the second position. A biasing assembly is operatively engaged with the valve element and is adapted to move the valve element from the second position towards the first position. The biasing assembly exerts a first force on the valve element during a first predetermined travel distance from the second position and a second force on the valve element during a second predetermined travel distance. The first force is greater than the second force.
