Claim 9:
10. A pressure-regulating device comprising:
a gas inlet;
an expansion body defining an expansion chamber that is in fluid communication with the gas inlet, the expansion body comprising a hollow protrusion extending, from a distal wall of the expansion body, upstream into the expansion chamber;
a first pressure regulation stage in fluid communication with the expansion chamber and configured to decrease gas pressure of a gas passing through the first pressure regulation stage, wherein the first pressure regulation stage includes a first valve, wherein an upstream opening of the hollow protrusion located within an interior of the expansion chamber communicates gas from the interior of the expansion chamber to the valve;
a second pressure regulation stage including a second valve arranged in series with the first valve such that gas flowing out of the first valve is communicated to an inlet of the second valve; and
a gas outlet positioned downstream from and in fluid communication with the first pressure regulation stage,
wherein the first valve and the second valve are substantially coaxially arranged, with a gas flow path through the pressure-regulating device extending substile along a longitudinal direction of the pressure-regulating device.
