Regulated gas supply system

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.

2. A regulated gas supply system for regulating the distribution of a highly pressurized gas to a desired pressure comprising:

a body defining a gas inlet to receive a highly pressured gas and a gas outlet to distribute a regulated gas;

a piston chamber defined in said body;

a secondary chamber defined in said body;

a piston slidably positioned in said piston chamber, said piston having piston channel traversing said piston and a piston extension to slidably engage said secondary chamber;

a spring biasing said piston within said piston chamber, and

a central channel extending through said piston and said piston extension.

3. The regulated gas supply system of claim 2 further comprising a vent aperture through said body, said vent aperture proximate said spring.

4. The regulated gas supply system as described in claim 2 wherein said piston chamber comprises:

an uppermost surface;

a seat opposing said uppermost surface; and

a chamber wall between said uppermost surface and said seat.

5. The regulated gas supply system as described in claim 4 wherein said piston comprises:

a piston body, wherein said piston channel traverses said piston body; and

a piston flange abutting said piston body, said piston flange engaging said chamber wall.

6. The gas regulating assembly of claim 5 , wherein said spring is positioned between said piston flange and said seat to urge said piston flange away from said seat.

7. A gas regulator for receiving a highly pressurized gas from a gas source and distributing the gas at a desired pressure, said regulator comprising:

a housing having an gas inlet and a gas outlet;

a piston chamber defined in said housing between said gas inlet and said gas outlet, said piston chamber including an uppermost surface, a seat opposing said uppermost surface, and a chamber wall connecting said uppermost surface with said seat;

a secondary chamber defined in said housing;

a piston slidably positioned in said piston chamber, said piston having a piston body with an abutting flange engaging said chamber wall, a piston channel traversing said piston body, a piston extension extending from said piston body to engage said secondary chamber, and a central channel traversing said piston; and

resilient means for urging said piston flange away from said seat, said resilient means positioned between said piston flange and said seat.

8. The regulator as described in claim 7 , wherein said resilient means comprises a spring.
