摘要： A pump including a pressure plate having two inlets and outlets, wherein each inlet has an auxiliary intake port in fluid communication with the inlet, and each outlet has an auxiliary discharge port in fluid communication with the outlet, and a cam/rotor assembly attached to the pressure plate. The cam/rotor assembly includes a rotatable cam having an opening, a rotor within the cam opening, the rotor having multiple radial slots, and multiple vanes that move within the slots, wherein a pumping chamber is defined by a space between rotor and cam. Rotor rotation within the cam causes the vanes to extend and retract within the pumping chamber. The movement of the vanes discharges into the outlets and auxiliary discharge ports a fluid drawn into the pumping chamber via inlets and auxiliary intake ports. The auxiliary inlet and auxiliary discharge ports reduce pressure pulsations in a variable displacement dual-lobe vane pump.
摘要翻译：一种包括具有两个入口和出口的压力板的泵，其中每个入口具有与入口流体连通的辅助入口，并且每个出口具有与出口流体连通的辅助排放口和附连到压板。凸轮/转子组件包括具有开口的可旋转凸轮，位于凸轮开口内的转子，转子具有多个径向槽以及在槽内移动的多个叶片，其中泵室由转子和凸轮之间的空间限定。凸轮内的转子旋转导致叶片在泵室内延伸和缩回。叶片的运动将通过入口和辅助进气口吸入泵送室的流体排入出口和辅助排出口。辅助进气口和辅助排气口可减小可变排量双叶叶片泵中的压力脉动。
