柱塞泵柱塞往复运动行程L是不变的，由凸轮的升程决定。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。供油开始时刻不随供油行程的变化而变化。转动柱塞可改变供油终了时刻，从而改变供油量。柱塞泵工作时，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。CTR3-050/P5.5/GP2-0158/A00N

(1)压力不均匀引起的噪声
先导型溢流阀的导阀部分是一个易振部位如图3所示。在高压情况下溢流时，导阀的轴向开口很小，仅0.003~0.006厘米。过流面积很小，流速很高，可达200米/秒，易引起压力分布不均匀，使锥阀径向力不平衡而产生振动。另外锥阀和锥阀座加工时产生的椭圆度、导阀口的脏物粘住及调压弹簧变形等，也会引起锥阀的振动。所以一般认为导阀是发生噪声的振源部位。
