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.
Claims20
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 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;
- 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;
- and
- a second stage valve element received into the cavity and movable in the cavity to open and close a second stage valve at the second valve seat,
- wherein the second stage valve element is movable toward the first valve seat to open the second stage valve.

- 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;
- 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;
- a second stage valve element received into the cavity and movable in the cavity to open and close a second stage valve at the second valve seat;
- and
- a retainer received in the cavity and defining a second bore in which the second stage valve element is movable relative to the second valve seat.
