ABSTRACT Apparatus for Aerating Liquids An apparatus for carbonating liquids is mounted on the inside of the door (1) of a domestic refrigerator, and a control lever (76) on the outside of the door is operable to control (i) the supply of water from a reservoir tank (7) to the carbonating chamber (8), (ii) the supply of gas from a cylinder (37) to the carbonating chamber for injection into the water, (iii) the operation of an exhaust valve (41) to release the gas pressure in the carbonating chamber (8), and the discharge of carbonated water from the chamber (8) to a nozzle (21) on the outside of the refrigerator door. Water flows into and out of the chamber through a single port (11) in the base of the chamber which houses a spool valve (16) reciprocable in opposite directions to connect the port (11) to the reservoir tank (7) and to the discharge nozzle (21).
