    摘要: An apparatus for controlling the opening and closing operation of a liquid flow valve dispensing fluid fed thereto from a reservoir, using the inherent gas pressure from the reservoir, comprising in combination (a) an actuator means operably connected to the flow valve for opening and closing the same; and (b) control means for controlling the operation of the actuator means, the control means comprising circuitry having pneumatic linear timer means and pneumatic control valve means operably connected one to another and to the actuator means. Also disclosed is a method of controlling the opening and/or closing operation of a liquid flow valve dispensing liquid fed thereto from a reservoir, using the inherent gas pressure from the reservoir.
