    摘要： A spool slides in a bore to open and close a valve. An armature moveable relative to the spool is biased in a first direction. A coupling biasing member biases the armature and the spool toward each other. When a solenoid is actuated the armature and the spool move in a second direction opposite the first direction until the spool forcibly engages a seat in the bore, closing the valve and stopping the spool movement. The armature continues to move in the second direction, causing the coupling to apply additional force to keep the spool engaged against the seat, until the armature reaches a second position where it forcibly engages with the spool. This stops the armature from moving further in the second direction, but allows the stationary armature to continue applying force to keep the spool engaged against the seat. When the solenoid is de-energized the armature bias sends the armature back in the first direction until it strikes the spool, causing the spool to rapidly unseat, thus opening the valve. Proper configuration of the spool and bore geometries in the vicinity of the seat keeps static pressure from developing that could otherwise retard spool valve opening.

    摘要翻译： 阀芯在孔中滑动以打开和关闭阀门。 可相对于线轴移动的衔铁在第一方向上偏置。 联接偏置构件使电枢和线轴朝向彼此偏置。 当螺线管被致动时，电枢和线轴沿与第一方向相反的第二方向移动，直到阀芯强制地接合孔中的阀座，关闭阀并停止阀芯运动。 电枢继续沿第二方向移动，使得联接器施加额外的力以保持线轴抵靠座椅，直到电枢到达其与阀芯强制接合的第二位置。 这使得电枢在第二方向上进一步移动，但允许固定电枢继续施加力以保持线轴抵靠座椅。 当螺线管断电时，电枢偏压将电枢向第一方向发回，直到其撞击阀芯，导致阀芯迅速下降，从而打开阀门。 座椅附近的阀芯和钻孔几何形状的正确配置保持静电压力不会妨碍滑阀打开。

    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 fuel injector for a common rail fuel system includes a common rail inlet port fluidly connected to a high pressure common rail, and a cooling inlet fluidly connected to an output from a lower pressure fuel transfer pump. The cooling fluid circulates internally through the fuel injector to cool a single pole solenoid via both internal and peripheral cooling passages. In order to accommodate a small spatial envelope while providing superior performance, a thin insulating layer may separate the solenoid coil winding from an inner pole piece, and small flux gap clearances may permit a flux carrying portion of the injector body to be a portion of the single pole solenoid assembly.

    摘要： A solenoid actuated device such as a fuel injector includes an actuator body having a plurality of body pieces, and a single-pole solenoid actuator assembly positioned at least partially within the actuator body. The single-pole solenoid actuator assembly includes a one-piece compound armature housing having a load carrying component clamped between the first body piece and the second body piece, and a flux carrying component. The load carrying component includes a high structural strength and a low flux permeability, and the flux carrying component includes a low structural strength and a high flux permeability. A method of making a solenoid actuated device includes placing an armature at a sliding radial air gap with a flux carrying component of a one-piece compound armature housing, and establishing a structural load path by placing a load carrying component of the compound armature housing between a first actuator body piece and a second actuator body piece. A method of operating a single-pole solenoid actuator device includes supporting a flux carrying component of a one-piece compound armature housing with a load carrying component of the compound armature housing, channeling magnetic flux across a sliding air gap between a flux carrying component and the armature, and channeling a clamping load between a first actuator body piece and a second actuator body piece through the load carrying component of the compound armature housing.

    摘要： A self-guided armature assembly for a single pole solenoid assembly includes an armature stem and an armature. The solenoid assembly includes a flux ring component and an actuator body. The armature is movable inside the flux ring. An axial air gap is defined between the top armature surface of the armature and a bottom stator surface of a stator assembly. A sliding air gap is defined between an inner diameter surface of the flux ring and an outer diameter surface of the armature. The self-guided armature is guided along the flux ring via a guiding interaction between the armature and the flux ring. The sliding air gap is smaller than the axial air gap. A stem clearance gap is defined between the armature stem and the actuator body. The sliding air gap is also smaller than the stem clearance gap.
