Abstract
The present disclosure relates to a self-contained high pressure pneumatic beverage dispensing system which includes a water pressurization and supply system. In one aspect of the invention, the water pressurization and supply system comprises a water pump having a piston cylinder and a piston that is disposed within the piston cylinder between the first and second ends of the cylinder. The water pump is adapted to be filled with high pressure gas on a first side of the cylinder through a gas inlet and further is adapted to be filled with water on a second side of the cylinder through a water inlet. In a further embodiment of the invention, the pressurization and supply system can further include a water pump control system that comprises a first piston sensor positioned adjacent the first end of the piston cylinder, a second piston sensor positioned adjacent the second end of the piston cylinder, and a water pump control valve operably connected to the first and second piston sensors and in fluid communication with the gas inlet of the piston cylinder.
