Abstract
A gas regulator includes a valve chamber body that houses two valves of the regulator. Valve elements that move to open and close the two valves are received via a same opening into the valve chamber body, which is closed by a plug. The plug can define a first valve seat as well as a piercing element used to pierce a compressed gas cylinder. A retainer can hold a gasket at a valve seat as well as provide a bore or other support for a valve element and valve element spring.

1-34. (canceled)
A pressure regulator comprising:
- a valve chamber body defining a cavity that extends from a first opening at a first end of the valve chamber body to a second opening at a second end of the valve chamber body, the valve chamber body defining a second valve seat in the cavity adjacent the second opening;
- a second stage valve element received into the cavity via the first opening, the second stage element being movable in the cavity toward the first end of the valve chamber body to open a second stage valve at the second valve seat, and moveable in the cavity toward the second end of the valve chamber to close the second stage valve;
- and
- a first stage valve element received into the cavity via the first opening, the first stage valve element being movable in the cavity toward the second end of the valve chamber body to open a first stage valve at a first valve seat to thereby control flow of pressurized gas into the cavity, and movable in the cavity toward the first end of the valve chamber body to close the first stage valve.
