Abstract
The present disclosure concerns a self-contained, pneumatic beverage dispensing system. In one embodiment, the pneumatic beverage dispensing system comprises a carbonator tank for facilitating absorption of CO.sub.2 gas in water to produce carbonated water, a source of CO.sub.2 gas under high pressure, the source of CO.sub.2 gas being in fluid communication with the carbonator tank so as to fill the carbonator tank with CO.sub.2 gas, and a source of water under high pressure, the source of water being in fluid communication with the carbonator tank so as to fill the carbonator tank with water. The system normally further comprises at least two liquid containers for containing liquids to be dispensed by the dispensing system, one of the liquid containers being in fluid communication with the source of CO.sub.2 gas, and a pneumatic pump system in fluid communication with the source of CO.sub.2 gas and the other of the liquid containers. In operation, the pneumatic pump system receives high pressure CO.sub.2 gas from the source of CO.sub.2 gas and uses it to pressurize air that is supplied to the other of the liquid containers.
