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。

工作时，在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下，迫使柱塞作上、下往复运动，从而完成泵油任务，泵油过程可分为以下三个阶段。
结论：通过上述讨论，得出下列结论
① 柱塞往复运动总行程L是不变的，由凸轮的升程决定。
② 柱塞每循环的供油量大小取决于供油行程，供油行程不受凸轮轴控制是可变的。
③ 供油开始时刻不随供油行程的变化而变化。
④ 转动柱塞可改变供油终了时刻，从而改变供油量。
3. 国产系列柱塞式喷油泵
国产系列柱塞泵主要有A、B、P、Z和Ⅰ、Ⅱ、Ⅲ号等系列。系列化是根据柴油机单缸功率范围对供油量的要求不同，以柱塞行程，泵缸中心距和结构型式为基础，再分别配以不同尺寸的柱塞直径，组成若干种在一个工作循环内供油量不等的喷油泵，以满足各种柴油机的需要。
国产系列喷油泵的工作原理和结构型式基本相同，以A型泵为例介绍柱塞式喷油泵的构造和工作原理。柱塞泵由四大部分组成：分泵、油量调节机构、传动机构和泵体
国产最新智能柱塞泵为微处理器智能控制，液晶屏显示，可与电脑进行通讯，具有工作压力稳定、脉动小、操作方便等特点。广泛用于生化、医药、化工、环保等行业，满足以上行业需要连续恒压、恒流输送液体的要求。

液压泵是液压系统的动力元件，其功用是给液压系统提供压力油，从能量转换角度讲，它将是原动机（如发动机）输出的机械能转换为便于输送的液体的压力能。液压马达则属于执行元件，它能将输入液体的压力能转换为输出轴转动的机械能，用来拖动负载做功。根据结构形式，液压泵与液压马达具体可分为齿轮式、叶片式、柱塞式等类型。
1.液压泵压力
液压泵工作压力是指泵（或马达）在实际工作时输出（或输入）油液的压力，由外负载决定。
额定压力是指在正常工作条件下，按试验标准规定能连续运转的最高压力。其大小受寿命的限制，若超过额定压力工作，泵（或马达）的使用寿命将会比设计的寿命短。当工作压力大于额定压力时称超载。
