ABSTRACT:
A gas pressure regulator includes a pressure regulator for connection to a source of high pressure gas, and flow meter or flow regulator that selectively varies the flow rate of delivered gas. The flow meter includes a ring with orifices of varying sizes radially spaced about a ring, with each orifice corresponding to a predetermined flow rate. A manually rotatable cap has a central axial bore and a spool extends through the aperture in both the ring and the central bore of the cap to secure them to the base of the flow meter. The spool has a shoulder which engages the ring to limit longitudinal displacement thereof. The spool also includes at least one bore extending through the shoulder. The bore communicates on one side with the delivered gas of the flow meter and on the other side with a nozzle extending along the axis from the end of the flow meter. Gas is delivered at the selected flow rate directly from the end of the flow meter, rather than from a transverse side.
