ABSTRACT:
A valve assembly and a regulator for use therein are disclosed. The valve assembly includes a valve poppet having a first end having a first face and a second end having a second face. The first face has a surface area smaller than the surface area of the second face. The second end of the valve poppet is received in a sealed chamber and a passage provides fluid communication between the inlet of the regulator and the chamber for allowing gas accumulating in the chamber to act on the second face for urging the valve poppet in the closed position without the use of a spring.
