ABSTRACT:
A metal regulator body is provided with a longitudinal bore, within which a tubular adjustor is threadably mounted for axial movement within the bore. A tire valve is threadably and sealably mounted within the tubular adjustor at one end thereof, and an expandable and contractable bellows is sealably fixed to the regulator body concentric with the tubular adjustor with the end of the bellows in abutment with one end of the tire valve stem. High pressure acetylene gas or the like from a supply tank feeds through the tire valve via the bellows to an outlet on the opposite side of the tire valve. The bellows on sensing a pressure above the pre-set value for the regulator instantly extending, causing the tire valve stem to follow the extension to limit the pressure of the available acetylene gas.
