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 shut-off 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 installa- tion of a gas storage cylinder which allows a novice to change the cylinder safely and quickly in a confined space. In another embodiment a diaphragm actuator directly contacts the slidable poppet within the cylinder shut-off valve to provide the gas flow controlling function in response to movement of the diaphragm. A high pressure gas storage cylinder fill adapter is also provided which has a pivot- able yoke and probe for secure attachment to the cylinder valve during the pressure refilling of the cylinder. In order to provide additional protection for the high pressure gas storage cylinder, the pressure regulator is mounted on a vertical surface or cabinet wall at suf- ficient height to allow the gas cylinder to be supported by the regulator when connected to the system. The regulator can be attached to the vertical surface by means of a bracket and releasable fasteners so that the re- gulator can be quickly removed, if desired.
