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. In the presence of an excessive pressure on diaphragm (98) of gas regulator valve means (E), a valve member (96) is caused to move against a spring (104) which determines the excess pressure level at, for example, 60 psi. Valve (96) moves until a valve tip (108) closes valve seat (84) closing off both restricted and unrestricted flows.
