Abstract:
1. A method for controlling the pressure of gas from a gas reservoir using a regulated gas supply system comprising the steps of: a) providing a body defining a piston chamber connected to the gas reservoir by a channel, said piston chamber having an uppermost surface, a seat, and a chamber wall connecting said uppermost surface with said seat; b) urging a piston in said piston chamber away from said seat with a spring; c) releasing gas from the gas reservoir into said piston camber, said gas flowing through a piston channel through said piston; d) applying a pressurized force on said piston flange opposite said spring; and e) forcing said piston into contact with said seat of said piston chamber to obstruct the flow of the gas through said piston channel; f) providing a secondary chamber and a central channel traversing said piston from a first end of said piston to a second end of said piston; g) engaging said secondary chamber with a first end of said piston; h) distributing gas through said central channel into said secondary chamber to balance said piston i) exerting said gas from said body through a gas outlet.
