它們也都采用閥式配流裝置，轉(zhuǎn)子裝在配流軸上。位于轉(zhuǎn)子中的徑向布置的柱塞，通過靜壓平衡的滑靴緊貼著偏心行程定子。而且大多為定量泵。是活塞或柱塞的往復(fù)運動方向與缸體中心軸平行的柱塞泵。煤礦液壓支架系統(tǒng)中的乳化液泵一般都是臥式柱塞泵。乳化液泵用于采煤工作面，才能操作機械。如果液壓油箱的氣壓不足時就啟動機器，會對液壓泵內(nèi)的滑靴造成拉脫現(xiàn)象，為液壓支架提供乳化液，工作原理靠曲軸的旋轉(zhuǎn)帶動活塞做往復(fù)運動，固定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊、壽命長、控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下實現(xiàn)吸液和排液。
