軸向柱塞泵（英文名：Piston pump）是活塞或柱塞的往復(fù)運(yùn)動方向與缸體中心軸平行的柱塞泵。軸向柱塞泵利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時(shí)可以達(dá)到很高的精度配合，因此容積效率高
直軸斜盤式

直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱，靠氣壓供油的液壓油箱，在每次啟動機(jī)器之后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就啟動機(jī)器，會對液壓泵內(nèi)的與滑靴造成拉脫現(xiàn)象，出會造成泵體內(nèi)回程板與壓板的非正常磨損。
徑向式

徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率

柱塞泵
低等缺點(diǎn)。國際上70、80年代發(fā)展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足。由于徑向泵結(jié)構(gòu)上的特點(diǎn)，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，改變定子的偏心距實(shí)現(xiàn)的，而定于的*大偏心距為 5—9mm（根據(jù)排量大小不同），變量行程很短。且變量機(jī)構(gòu)設(shè)計(jì)為高壓操縱，由控制閥進(jìn)行控制。故該泵的響應(yīng)速度快。徑向結(jié)構(gòu)設(shè)計(jì)克服了如軸向柱塞泵滑靴偏磨的問題。使其抗沖擊能力大幅度提高。
液壓式

液壓柱塞泵靠氣壓供油的液壓油箱，在每次啟動機(jī)器后，必須等液壓油箱達(dá)到使用氣壓后，才能操作機(jī)械。直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無需外力供油。

屬于一種新型的技術(shù)含量比較高的高效泵，隨著國產(chǎn)化的不斷加快，徑向柱塞泵必然會成為柱塞泵應(yīng)用領(lǐng)域的重要組成部分；具體詳見徑向柱塞泵百科，以下僅以軸向柱塞泵為例進(jìn)行解釋。
軸向柱塞泵是利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時(shí)可以達(dá)到很高的精度配合，因此具有容積效率高，運(yùn)轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點(diǎn)，但對液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價(jià)較高。

柱塞泵的泵油機(jī)構(gòu)包括兩套精密偶件：柱塞（plunger）+柱塞套(barrel)構(gòu)成柱塞偶件(plunger and barrel assembly)（圖5-11）、出油閥（delivery valve）和出油閥座(delivery valve seat)構(gòu)成出油閥偶件(delivery valve assembly
柱塞和柱塞套是一對精密偶件，經(jīng)配對研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm
柱塞頭部圓柱面上切有斜槽，并通過徑向孔、軸向孔與頂部相通，其目的是改變循環(huán)供油量；柱塞套上制有進(jìn)、回油孔，均與泵上體內(nèi)低壓油腔相通，柱塞套裝入泵上體后，應(yīng)用定位螺釘定位。
柱塞頭部斜槽的位置不同，改變供油量的方法也不同。
