Carbonator valve
First Claim
1. In a drink dispenser for dispensing carbonated drinks which includes a source of carbon dioxide at high pressure and a source of carbon dioxide at a lower pressure, said lower pressure being a pressure utilized for dispensing carbonated water, a method of quickly batch carbonating water within a carbonator tank having a head space comprising the steps of:
- (a) admitting carbon dioxide to the carbonator tank at said higher pressure until a pressure intermediate said higher and lower pressure is reached in said head space; and
(b) venting the head space of the carbonator to said lower pressure.

Abstract
In a drink dispenser for dispensing carbonated drinks which includes a source of carbon dioxide at high pressure and a source of carbon dioxide at a lower pressure, the lower pressure being a pressure utilized for dispensing carbonated water, water within a carbonator tank is quickly carbonated by admitting carbon dioxide to the carbonator at the higher pressure until a pressure intermediate the higher and lower pressure is reached, venting the head space of the carbonator to the lower pressure, and, preferably, of repeating these steps a plurality of times.

4. In a drink dispenser for dispensing carbonated drinks including a batch carbonator with a sparger through which carbon dioxide may be admitted for carbonating still water within the carbonator, a head space being provided over the water in the carbonator, said system including a source of high pressure carbon dioxide and a source of lower pressure carbon dioxide, a carbonating valve comprising:
-
(a) means, for coupling the higher pressure carbon dioxide to the sparger upon actuation of said valve; (b) a pressure relief valve set to operate at a pressure intermediate said higher and lower pressures coupled to the head space of said carbonator; and (c) means to couple said head space to said lower pressure when said carbonating valve is returned to an unactuated position after operation of said pressure relief valve thereof, whereby said head space will be vented to said lower pressure. - View Dependent Claims (5, 6, 7, 8, 9, 10)
