Abstract A pressuretight receptacle contains the water or other liquid to be saturated with gas, such as carbon dioxide gas supplied to it from a conventional carbon dioxide cylinder, through an elongated capillary tube leading to a porous sintered powdered metal diffuser which creates a myriad of small bubbles of the gas which, passing upward through the liquid, saturates the liquid with gas. The elongated capillary tube retards the flow of gas to the diffuser and thereby prevents the gas bubbles from being discharged therefrom too rapidly for the liquid to absorb them. The surplus gas not absorbed by the liquid collects in the top space above the liquid level and serves as a pressurized chamber to dispense the carbonated liquid through a dispensing pipe leading to the bottom of the receptacle. The diffuser is supported by a pipe through which the capillary tube extends and is protected thereby.
A self-contained absorption gas charger for liquids, according to claim 1, wherein said gas-flow-retardation tube has an internal diameter not exceeding thirty-five thousandths of an inch.

Claim 3
Dependent Claim
36 words
A self-contained absorption gas charger for liquids, according to claim 1, wherein said diffuser support is connected to said receptacle near said gas inlet connection, and wherein said gas-flow-retardation tube extends downward adjacent said diffuser support.
Claim 4
Dependent Claim
38 words
A self-contained absorption gas charger for liquids, according to claim 1, wherein said diffuser support consist of a pipe connected to said receptacle near said gas inlet connection, and wherein said gas-flow-retardation tube extends downward inside said pipe.
Claim 5
Dependent Claim
37 words
A self-contained absorption gas charger for liquids, according to claim 5, wherein said diffuser has a bored portion at one side thereof, and wherein the lower end portion of said pipe is secured in said bored portion.
Claim 6
Dependent Claim
23 words
A self-contained absorption gas charger for liquids, according to claim 1, wherein said diffuser has pores therein of a size approximating 5 microns.
