力士乐A4VSO型轴向柱塞变量泵的使用压力一般应在10MPa～100MPa之间。它属于容积式泵，借助工作腔里的容积周期性变化来达到输送液体的目的；原动机的机械能经泵直接转化为输送液体的压力能；泵的容量只取决于工作腔容积变化值及其在单位时间内的变化次数，理论上与排出压力无关。力士乐A4VSO型轴向柱塞变量泵是借助于活塞在液缸工作腔内的往复运动（或通过隔膜、波纹管等挠性元件在工作腔内的周期性弹性变形）来使工作腔容积产生周期性变化的。在结构上，往复泵的工作腔是借助密封装置与外界隔开，通过泵阀（吸入阀和排出阀）与管路沟通或闭合。

Rexroth柱塞泵，力士乐杭州经销，的技术参数及安装注意事项：

  分为普通的和适于HFC油液的。特别适合使用HFC油液运行，使用*的HFC油液运行设备时，获得的速度和压力可以与使用矿物油时获得的速度和压力相同。它们的共同点：采用斜盘设计的轴向柱塞泵，适用于开路中的液压传动装置，流量与输入传动速度和排量成比例。通过调整斜盘角度，可对输出流量进行无级调节。
