buffer piston meaning in Chinese

缓冲器活塞

Barrel buffer piston rod assembly
枪管缓冲器活塞杆组件
Many researches have been done with the simulation model . it was found that some structure parameters such as the diameter of the driving piston , the diameter of the buffer piston , the stiffness of the valve spring , the compress ratio of the buffer piston , and the flux area of the solenoid valve etc . have great effect on the performance of the haecvvs . for certain performance demand of the variable vale system , there is a most suitable combination for the structure parameters
通过对电控可变气门系统的主要结构参数，如动力活塞直径、缓冲活塞直径、气门弹簧刚度、缓冲活塞实际压缩比、电磁阀通流面积等参中压共轨电控柴油机可变气门系统的研究数对电控可变气门系统启、闭特性的影响规律的研究发现，动力活塞直径、气门弹簧刚度、电磁阀通流面积对电控可变气门系统启、闭性能起着决定性的作用，对于一定的气门启闭规律要求，这些结构参数存在一组最佳值。
