摘　　要：利用无返回力矩擒纵机构控制液压阀的开闭,设计一种新型可定时液压阀。并针对该阀开启时出现的瞬态冲击设计了一种避免瞬态冲击力矩放大机构。对该阀的无返回力矩擒纵机构在理论上进行了初步分析,并结合实际,提出无返回力矩擒纵机构在给定周期条件下的设计准则。Making use of runaway escapement to control the valve working state, a new kind of timing valve was designed. And enlarge mechanism specifically for the valve been design to avoid moment pounding force, the first step analysis has carried out In theory on the runaway escapement of the valve. According to the use condition, the runaway escapement design criteria were given under the given period.

关 键 词：定时换向阀 无返回力矩擒纵机构 战术力矩
