Abstract:
Apparatus is provided for automatically carbonating a liquid. A pressure vessel receives carbonating gas at a pressure P. sub. 1 via a first input, and a supply of liquid at a pressure P. sub. 2 via a second input. P. sub. 2 is greater than P. sub. 1. The flow of liquid into the pressure vessel is restricted, to enable carbonating gas to enter the vessel and substantially reach the pressure P. sub. 1 therewithin before liquid entering the vessel raises the interior pressure above P. sub. 1. An output is provided for drawing carbonated liquid out of the pressure vessel. The apparatus is particularly suitable for residential use in providing Seltzer water, where it operates at conventional municipal or private well water pressures.
