分析了目前液压冲击器配油阀的工作原理及能量损失，设计了一种新型液压冲击器配油阀，经理论计算分析证明，新型配油阀泄漏少，压力损失小，能耗低，采用新型配油阀的液压冲击器效率高．
The working principle and energy loss of hydraulic impactor oil distribution valve are analyzed. A new type of hydraulic impactor oil distribution valve is designed. Theoretical calculations show that the new oil distribution valve has less leakage, less pressure loss and low energy consumption. The new hydraulic valve hydraulic valve with high efficiency.
