Abstract: A carbonator valve assembly (A) is disclosed which includes a water valve entrance subassembly (B), a gas regulator valve entrance subassembly (C), and a vent valve subassembly (D) formed in a valve head (12) sealingly fitted in a neck of a carbonator tank (10). Gas entrance regulator valve subassembly (C) includes a pressure regulator-delivery valve means (E) which delivers a restricted flow of pressurized gas to a gas dispensing chamber (80) via a passage (100) and restricted outlet port (102). An unrestricted path for the pressurized gas is established through the carbonator valve assembly (A) via a control valve chamber (56) passage (64), chamber (62), passage (70), chamber (72), passage (78), and dispensing chamber (80). Dispensing chamber (80) includes valve seat (84) through which both the restricted and unrestricted gas flows enter the carbonator tank.

Abstract: A refrigeration system for cooling beverages as they are drawn from a plurality of containers and dispensed through a plurality of faucets. A pair of beverage dispensing coils are centrally carried in a housing which is filled with water. A refrigeration coil encircles the housing causing a build up of ice to take place on the inner wall of the housing. A temperature sensor is carried within a helical coil provided between the beverage dispensing coil and the ice bank for operating a compressor associated with the refrigeration coil. A power-driven paddle is centrally carried within the container for circulating the water therein and a gentle, wiping motion. In order to selectively turn on and off the power paddle, a second temperature sensor is located in a junction provided between the inputs of the beverage dispensing coils.
