Abstract
A pneumatic valve controller is provided for use with a refillable gas tank that has an inlet and an outlet with a spring-loaded valve disposed in the outlet. The spring-loaded valve is biased to define a flow path between an interior of the gas tank and the outlet. The controller's housing includes a cylinder with a gas filling port in fluid communication with a first axial end of the cylinder. The cylinder's second axial end is open and aligned with the spring-loaded valve. A piston is disposed in the cylinder. A check valve has an input and an output with the input in fluid communication with the gas filling port and the output in fluid communication with the inlet of the gas tank.
