美國威格士柱塞泵*柱塞泵分為軸向柱塞泵和徑向柱塞泵兩種代表性的結(jié)構(gòu)形式；由于徑向柱塞泵  柱塞泵
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 　?。灰韵聝H以軸向柱塞泵為例進行解釋。 　　威格士VICKERS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)運動所產(chǎn)生的容積變化來進行工作的。由于柱塞和柱塞孔都是圓形零件，加工時可以達到很高的精度配合，因此具有容積效率高，運轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點，但對液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價較高。 　　MCY14-1B：定量柱塞泵 　　SCY14-1B：手動變量柱塞泵 　　YCY14-1B：壓力變量柱塞泵 　　BCY14-1B：電液控制柱塞泵 　　PCY14-1B：恒壓變量柱塞泵 　　柱塞泵的泵油機構(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、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。 　　出油閥和出油閥座也是一對精密偶件，配對研磨后不能互換，其配合間隙為0.01mm 。 　　VICKERS出油閥是一個單向閥，在彈簧壓力作用下，閥上部圓錐面與閥座嚴密配合，其作用是在停供時，將高壓油管與柱塞上端空腔隔絕，防止高壓油管內(nèi)的油倒流入噴油泵內(nèi)。 　　出油閥的下部呈十字斷面，既能導(dǎo)向，又能通過柴油。出油閥的錐面下有一個小的圓柱面，稱為減壓環(huán)帶，其作用是在供油終了時，使高壓油管內(nèi)的油壓迅速下降，避免噴孔處產(chǎn)生滴油現(xiàn)象。當環(huán)帶落入閥座內(nèi)時則使上方容積很快增大，壓力迅速減小，停噴迅速。
