This choke valve, during cold engine starting, starts fuel to flow through the main system prematurely.
在冷启动时，阻风门使燃油提早进入主供油装置。
It is a long time since the traditional mechanismic speed governing system has been used for control the speed of turbine. It has so much defects as choke, leakage, wide velocity perturbation.
长期以来，透平机一直使用传统的机械调速系统来控制其转速，卡涩、液压系统渗漏及转速波动范围大等均属其不可克服的缺陷。
