ABSTRACT:
A regulated gas pressurization system for a beverage dispenser which includes a pressure regulator, cylinder valve, and quick coupling apparatus provided for securely connecting the valve and regulator for safe operation. The regulator includes an adjustably biased diaphragm which operates a control valve which regulates the flow of gas from a gas storage cylinder to the beverage dispenser. The adjustment of the biasing force on the diaphragm determines the outlet pressure in the system. A pivotable yoke which is part of the coupling apparatus is placed in a raised position so that the cylinder shutoff valve can be properly aligned with the regulator boss and lowered to a retaining position where a retaining screw can be turned inwardly to move the cylinder valve into rigid coupling position with the regulator. Upon coupling, a poppet within the cylinder valve is opened automatically to allow gas to flow into the regulator. This arrangement permits a short lateral sliding movement for installation of a gas storage cylinder which allows a novice to change the cylinder safely and quickly in a confined space.
