Claim 0:
1. 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 at a distal end region 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 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;
an inflow member coupled to and extending proximally from the hollow protrusion, the inflow member comprising a passageway for communicating gas from the expansion chamber to the valve;
an intermediate regulator body having a proximal end region and threadedly coupled to the expansion body such that changing a distance between the distal end region of the expansion body and a proximal end region of the intermediate regulator body changes an amount of pressure decrease produced by the first pressure regulation stage; and
a gas outlet positioned downstream from and in fluid communication with the first pressure regulation stage.
