 REXROTH柱塞泵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 REXROTH柱塞泵部圓柱 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，力士樂柱塞套裝入泵上體后， 應用定位螺釘定位。 REXROTH液壓泵部斜槽的位置不同，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 。 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。
