柱塞和柱塞套是一对精密偶件,经配对研磨后不能互换,要求有高的精度和光洁度和好的耐磨性,其径向间隙为0.002~0.003mm
柱塞头部圆柱面上切有斜槽,并通过径向孔、轴向孔与顶部相通,其目的是改变循环供油量;柱塞套上制有进、回油孔,均与泵上体内低压油腔相通,柱塞套装入泵上体后,应用定位螺钉定位。
柱塞头部斜槽的位置不同,改变供油量的方法也不同。
出油阀和出油阀座也是一对精密偶件,配对研磨后不能互换,其配合间隙为0.01mm 。
出油阀是一个单向阀,在弹簧压力作用下,阀上部圆锥面与阀座严密配合,其作用是在停供时,将高压油管与柱塞上端空腔隔绝,防止高压油管内的油倒流入喷油泵内。
出油阀的下部呈十字断面,既能导向,又能通过柴油。出油阀的锥面下有一个小的圆柱面,称为减压环带,其作用是在供油终了时,使高压油管内的油压迅速下降,避免喷孔处产生滴油现象。当环带落入阀座内时则使上方容积很快增大,压力迅速减小,停喷迅速。
