Abstract:
     The pressure regulation with damping capillary and the pressure controlling valve are presented in the patent. The angular displacement signal is converted into pressure signal by means of the uniform pressure variation in the capillary to control the pressure of outlet or inlet of a valve. The signal conversion stage and the power amplifying stage of a two-stage valve may be mounted on one valve core. The said valve has simple structure, high repeat accuracy, good stability and low cost.
