美國(guó)VICKERS威格士柱塞泵是依靠柱塞與缸體內(nèi)孔面來形成密封工作容積的。由于柱塞與缸體內(nèi)孔均為圓柱表面，因此加工方便，配合精度高，密封性能好。故柱塞泵常做成高壓泵。
優(yōu)點(diǎn)：壓力高、結(jié)構(gòu)緊湊、效率高及流量調(diào)節(jié)方便。
缺點(diǎn)：結(jié)構(gòu)復(fù)雜，價(jià)格較貴。
柱塞泵按柱塞排列方向的不同，分為軸向柱塞泵和徑向柱塞泵。在此，簡(jiǎn)要介紹軸向柱塞泵和回轉(zhuǎn)式徑向柱塞泵。
軸向柱塞泵。軸向柱塞泵由配流盤、缸體（轉(zhuǎn)子）、柱塞和斜盤等主要零件組成。在配流盤上開有兩個(gè)弧形溝槽，分別與泵的吸、壓油口連通，形成吸油腔和壓油腔。斜盤、配流盤均與泵體相固定，柱塞在彈簧的作用下以球形端頭與斜盤接觸。兩個(gè)弧形溝槽彼此隔開，保持一定的密封性。斜盤相對(duì)于缸體的夾角為γ。原動(dòng)機(jī)通過傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)，柱塞就在柱塞孔內(nèi)作軸向往復(fù)滑動(dòng)。處于π～2π范圍內(nèi)的柱塞向外伸出，使其底部的密封容積增大，將油吸入；處于0～π范圍內(nèi)的柱塞向缸體內(nèi)壓入，使其底部的密封容積減小，把油壓往系統(tǒng)中。
顯然，泵的輸油量決定于柱塞往復(fù)運(yùn)動(dòng)的行程長(zhǎng)度，也就是決定于斜盤的傾角γ。如果γ角可以調(diào)整，就成為變量泵。γ角越大，輸油量也就越大。
徑向柱塞泵。所示當(dāng)轉(zhuǎn)子旋轉(zhuǎn)時(shí)，柱塞在離心力作用下，它的頭部與定子內(nèi)表面緊緊接觸，由于轉(zhuǎn)子與定子之間有一個(gè)偏心量е，所以柱塞在隨轉(zhuǎn)子轉(zhuǎn)動(dòng)的同時(shí)，又在柱塞孔內(nèi)作徑向往復(fù)滑動(dòng)。當(dāng)轉(zhuǎn)子按圖中箭頭所示方向旋轉(zhuǎn)時(shí)，上半周的柱塞皆往外滑動(dòng)，柱塞孔內(nèi)的密封容積增大，于是通過軸向孔吸油；下半周的柱塞皆往里滑動(dòng)，柱塞孔內(nèi)的密封容積減少，于是通過軸向孔壓油。
