Abstract:
A gas regulator comprising:a first body having an inlet for receiving gas at high pressure from a gas source thereof and a fluid passage in fluid communication with said inlet that extends through said first body, said first body further including an outlet in fluid communication with said fluid passage;a second body having an inlet, a pressure reduction cavity, a first fluid passage in fluid communication with said inlet and said pressure reduction cavity, a gauge cavity, a viewport aperture fluidly communicating with said gauge cavity, and a second fluid passage in fluid communication with said first fluid passage and said gauge cavity;a helical coil Bourdon tube having a sealed end and an open end and disposed within said gauge cavity and wherein the open end of said Bourdon tube is fluidly connected to said second fluid passage where said second fluid passage communicates with said gauge cavity;a pressure indicator disposed in said gauge cavity and attached to said Bourdon tube, and wherein said pressure indicator is viewable through said viewport aperture;pressure reducing means including a low pressure outlet disposed within and fluidly sealing said pressure reduction cavity, said pressure reducing means reducing the gas pressure in said pressure reduction cavity to a predetermined lower pressure and supplying the predetermined lower pressure gas to said low pressure outlet;clamp means for attaching said first body to the gas source so that high pressure gas is supplied to said inlet of said first body; andmeans for attaching said first body to said second body, said means for attaching including means for fluidly connecting said outlet of said first body to said inlet of said second body.
