　　PCY14-1B：恒壓變量柱塞泵 　　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(duì)精密偶件，經(jīng)配對(duì)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。 　　出油閥和出油閥座也是一對(duì)精密偶件，配對(duì)研磨后不能互換，其配合間隙為0.01mm 。 　　出油閥是一個(gè)單向閥，在彈簧壓力作用下，閥上部圓錐面與閥座嚴(yán)密配合，其作用是在停供時(shí)，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?jǐn)嗝妫饶軐?dǎo)向，又能通過柴油。出油閥的錐面下有一個(gè)小的圓柱面，稱為減壓環(huán)帶，其作用是在供油終了時(shí)，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(dāng)環(huán)帶落入閥座內(nèi)時(shí)則使上方容積很快增大，壓力迅速減小，停噴迅速。 廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場(chǎng)合，諸如液壓機(jī)、工程機(jī)械和船舶中。。38.1KTC2HGC49MC1100M1144。
