Abstract
A valve for controllably admitting a pressurized gas into a bottle and dispensing a liquid from the bottle. The valve attaches to the top of an opened bottle and includes a valve body having a liquid section and a gas section. An intake tube descends from the valve body into the bottle and communicates with a liquid outlet spout through the liquid section of the valve body. Gas from a source of pressurized gas is controllably admitted through the valve body into the neck of the bottle to force the liquid within the bottle up the intake tube and into the liquid section of the valve body. A finger actuated trigger operates against a valve slide to selectively control opening and closing of the liquid and gas sections of the valve body. Valving is arranged so that communication between the liquid inlet and liquid outlet is always established before gas is admitted into the bottle and is maintained until after the gas supply is closed. This assures that excess gas pressure cannot accumulate within the bottle and that the liquid is exposed to a minimum pressure. The dispensing valve also includes a quick disconnect coupling so that the supply of pressurized gas may be conveniently disconnected from the dispensing valve while maintaining a sealed air-free atmosphere within the bottle.
