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.

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;
- a plug engaged at the first end of the valve chamber body, the plug defining a first valve seat on an inner side of the plug in the cavity and having a piercing element located on an outer side of the plug outside of the cavity and configured to pierce a gas outlet of a gas cylinder, the plug having a gas pathway extending from the piercing element to the first valve seat;
- and
- a first stage valve element movable in the cavity to engage with and disengage from the first valve seat and thereby to open and close a first stage valve to control flow of pressurized gas into the cavity.
