摘要： A closed, self-sustaining power system for the operation of valves includes a first means for storing and containing an expandable system which means communicates with a responsive means of a valve system to enable the valve system to be opened, closed or controlled. A controlled energy means transmits energy to the expandable medium to thereby cause an increase in pressure in the responsive means of the valve system which enables the valve system to respond as desired. After actuation of the responsive means of the valve system, the means for storing is enabled to communicate with a reservoir means which thereby increases the area of the closed system to reduce the pressure in the closed system sufficiently to terminate actuation of the responsive means of the valve system.
