美国VICKERS威格士径向柱塞泵，威格士径向柱塞泵工作原理：
威格士柱塞泵是往复泵的一种，径向柱塞泵可分为阀配流与轴配流两大类。阀配流径向柱塞泵存在故障率高、效率低等缺点。上70、80年代发展的轴配流径向柱塞泵克服了阀配流径向柱塞泵的不足。由于径向泵结构上的特点，陕定了轴配流径向柱塞泵比轴向柱塞泵耐冲击、寿命长、控制精度高。变量行程短泵的变量是在变量柱塞和限位柱塞作用下，改变定子的偏心距实现的，而定于的zui大偏心距为5—9mm（根据排量大小不同），变量行程很短。且变量机构设计为高压操纵，由控制阀进行控制。故该泵的响应速度快。径向结构设计克服了如轴向柱塞泵滑靴偏磨的问题。使其抗冲击能力大幅度提高。
