ABSTRACT:
A carbonator which includes first and second chambers separated by a movable piston may be used on earth or in the microgravity conditions of outer space. The volume of either chamber are correspondingly increased or reduced due to the movement of the piston. The first chamber can receive carbon dioxide gas at a predetermined pressure. A conduit can thereafter be opened between the chambers to permit the carbon dioxide gas to flow to the second chamber. A spring is provided to cause said piston to move so as to reduce the volume of the first chamber and force the carbon dioxide gas into the second chamber after the two chambers are placed in communication. The conduit is then closed and water at a selected pressure is introduced into the second chamber. Due to the various pressures, the water and carbon dioxide gas mix to form carbonated water. An agitator can be used to aid this mixing. Carbonated water is then formed and this water may then be discharged from the carbonator as the movable piston is moved to reduce the volume of the second chamber. This piston is now moved in response to opening of a valve to permit the carbonated water discharge and in response to reintroduction of carbon dioxide gas into the first chamber. The foregoing steps may then be repeated to permit sequential discharges of carbonated water.
