A domestic carbonator for gasifying liquid in a container comprising a cap for the container having an injector passage closed by a one-way non-return valve in combination with a main body having pressure-reducing discs, an injector piston for initiating a gas flow, a pressure relief valve and a pressure gauge. The main body is provided with an opening for receiving a CO2 cylinder with a further piston for cutting off the gas supply under the effect of the back pressure from the container.

Apparatus for gasifying liquid in a container comprising a cap for said container having an injector passage closed by a one-way non-return valve in combination with a body having means for mounting a cylinder of pressurized gas of the type having a flow control valve for supplying a flow of gas at supply pressure, said body having reduction means for receiving the gas from said cylinder, a passageway connecting said reduction means to an outlet configured for mating engagement with said injector passage of said cap, a control valve means comprising an injector piston incorporating said outlet and moveable between a non-depressed position and depressed position and a control piston urged by said supply pressure of gas to a shut off position whereat said control piston shuts off the flow of gas through said passageway and urges said injector piston to said non-depressed position, and moveable by the movement of said injector piston to said depressed position to an open position whereat said control piston allows the flow of gas through said passageway to said outlet, and a pressure relief valve connected to said passageway at a point in continuous communication with said outlet and wherein said apparatus includes sealing means associated with said cap or said body for providing a seal between said outlet and said injector passage of said cap, wherein said reduction means and said control valve means are for controlling the flow of gas to said outlet and wherein said injector piston is for movement to said depressed position by said cap.
