凸轮控制阀 meaning in English

cam operated control valve
cam-operated valve

The dissertation also does a research on the control strategies of mechanical control parts . the theoretical expression among needle valve throttle area , cam - control valve throttle area and the equivalent throttle area of combining control is given , and the principle of combining control of the two valves is analyzed . the arresting control strategies under various engaging conditions are presented , namely the engaging condition of same overrunning length and same engaging speed but different weight , the engaging condition of same overrunning length and same weight but different speed as well as the engaging condition of same weight and same engaging speed but different overrunning length
研究了机械控制机构的控制策略：从理论上推导出了针阀节流面积、凸轮控制阀节流面积及联合控制的当量节流面积三者之间的关系表达式；分析了针阀与凸轮阀联合控制的控制原理和方法；给出了同拦停距离同撞网速度不同重量飞机撞网状况、同拦停距离相同重量不同撞网速度飞机撞网状况以及同重量飞机同撞网速度不同拦停距离撞网状况的拦阻控制策略。
