<p>An apparatus for supplying gas at a reduced pressure from a pressure vessel containing a gas under pressure and having an outlet valve fitted thereon has a plurality of nozzle means. A plurality of stacked spaced-apart chamber means communicates with, and is disposed so as to be alternately supported between the plurality of nozzle means. One of the nozzle means is an inlet nozzle communicating with the gas under pressure. Another of the nozzle means is an outlet nozzle communicating with the outlet valve to thereby provide an expansion path for the gas. Additionally, the apparatus includes a receiving tube disposed about the stacked array of alternately placed nozzle means and chamber means with one end of the receiving tube threadably engaging the outlet valve.</p> |
