美國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：壓力高、結(jié)構(gòu)緊湊,、效率高及流量調(diào)節(jié)方便。
缺點：結(jié)構(gòu)復雜,，價格較貴,。
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,。兩個弧形溝槽彼此隔開,，保持一定的密封性,。斜盤相對于缸體的夾角為γ。原動機通過傳動軸帶動缸體旋轉(zhuǎn),，柱塞就在柱塞孔內(nèi)作軸向往復滑動,。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運動的行程長度,，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,。所示當轉(zhuǎn)子旋轉(zhuǎn)時,，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偏心量е,，所以柱塞在隨轉(zhuǎn)子轉(zhuǎn)動的同時,，又在柱塞孔內(nèi)作徑向往復滑動,。當轉(zhuǎn)子按圖中箭頭所示方向旋轉(zhuǎn)時，上半周的柱塞皆往外滑動,，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,，柱塞孔內(nèi)的密封容積減少，于是通過軸向孔壓油,。
