    摘要： A power steering pump comprises a housing that includes a bore, a fluid discharge port that supplies pumped fluid into the bore, and a fluid bypass port for recycling excess fluid to the pumping elements. A flow control valve is slideably received in the bore and regulate the size of the inlet to the fluid bypass port. The pump includes a solenoid assembly that has a plunger that is operatively connected to the flow control valve. By adjusting the magnitude of the current to the electromagnetic coil of the solenoid assembly, the position of the flow control valve is varied to increase or decrease fluid flow to the fluid bypass port and thereby regulate the output from the pump.

    摘要翻译： 动力转向泵包括壳体，其包括孔，将泵送的流体供应到孔中的流体排出口以及用于将多余流体再循环到泵送元件的流体旁路端口。 流量控制阀可滑动地容纳在孔中并调节流体旁路端口的入口的尺寸。 泵包括具有可操作地连接到流量控制阀的柱塞的螺线管组件。 通过调节电磁线圈组件的电磁线圈的电流大小，可以改变流量控制阀的位置，以增加或减少流体流向旁路端口的流体，从而调节泵的输出。
