压力阀是靠弹簧力与液体压力的平衡来控制阀体上油道的开闭，系统的高压力是由溢流阀调定的，系统的
工作压力由外载荷决定。压力阀的工作原理如图1所示，从液压泵来的油进入B腔后，由于两边面积相等，故对阀芯没有轴向推力。在图1(a)所示位置时，弹簧推动阀芯把P口与T口隔断，油液没有泄漏，系统压力升高，A腔内的压力也随之升高，向下压缩弹簧的力不断，直至超过弹簧的推力，使阀芯向下运动，如图1(b)所示。由于P口与T口接通，压力油经T口泄回油箱，系统压力下降，A腔压力也随之降低，当油压力低于弹簧力时，阀芯上移，又切断P口与T口的联系，油液不能泄漏，压力又上升，阀芯这样不停地交替动作，系统压力就在动态中实现平衡，稳定在某一值，这就是压力阀的工作原理。 [2]
