ABSTRACT:
A gas flow governor for regulating the inlet of carbonic acid gas under high pressure delivered from a source of gas and the outlet of expanded gas, the governor comprising a piston slidable in a bore of a body and forming a chamber receiving expanded gas. The piston is acted on by springs to tend to reduce the size of the chamber and the piston has a rod with a rivet head shaped end on which is fixed with play a Teflon plunger of a valve member, the plunger having a frustoconical end. The rod with the plunger slides in a bushing having a cap with a coaxial inlet orifice for connecting with the gas source and an output orifice perpendicular to the inlet orifice and forming with the latter a shoulder with a valve seat.
