摘　　要：在高压共轨系统中限压阀是重要的安全阀,用于保障共轨管内的燃油压力在阈值以内,避免因轨压过大导致共轨管及其他装置损坏。本文简要介绍了高压系统限压阀的工作原理,并对常见的冲阀故障及原因进行解析,通过实例为相关设计及应用人员提供参考。In the high-pressure common rail system,the pressure reducing valve is an important safety valve,which is used to ensure that the fuel pressure in the common rail pipe is within the threshold and avoid the damage of the common rail pipe and other devices due to excessive rail pressure.This article briefly introduces the working principle of pressure reducing valve in high-pressure system,analyzes the common flush valve faults and their causes,and provides reference for relevant designers and application personnel through examples.
