Abstract
A self-contained high pressure pneumatic beverage dispensing system configured for portable or fixed installations. The beverage system is designed to dispense carbonated and noncarbonated mixed beverages, as well as any carbonated and noncarbonated unmixed beverages in liquid form. In particular, the self-contained pneumatic beverage dispensing system includes a high pressure carbonator tank, a refillable source of CO.sub.2 gas at high pressure, a source of pressurized water, a carbonator tank water level switch and water valve, and a beverage dispenser valve. In a first embodiment, the source of pressurized water comprises a high pressure water tank containing water that is pressurized with CO.sub.2 gas. In a second embodiment, the source of pressurized water comprises a low pressure water tank, and a high pressure water pump that is used to raise the pressure of the water supplied by the low pressure water tank. In a third embodiment, the source of pressurized water comprises a large pneumatically-controlled single cycle high pressure pump. In all of the embodiments, the carbonator tank water level switch sends either a pneumatic or electrical signal to the carbonator tank water…
