  • Patent number: 5152935
    Abstract: Provided is a carbonation system which does not require repetitive steps of manually refilling a water container thereof. The system sets forth a combination of a pre-cooled water source, a carbonation vessel, a assembly for regulating an inflow of pre-cooled water from the water source to the carbonation vessel, a source of compressed carbonation gas having an input to the carbonation vessel, and an assembly for providing selectable bursts of the carbonation gas to the carbonation vessel after the carbonation vessel has been filled, between defined maxima and minima, with a quantity of pre-cooled water. By the use of an external faucet, carbonated water may be removed from the carbonation vessel. A burst of carbonation gas is provided to the chilled water in the carbonation vessel after it is filled. The vessel is also immersed in the source of pre-cooled water. The vessel will self-fill after the carbonated water is drawn off.
