    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。
