Abstract: A back pressure filling valve for bottles comprises a central ventilation tube slidably mounted within a valve body member with clearance therebetween to provide an auxiliary passage for the air or gas. A frusto-conical check valve of elastomeric material controls this passage. A liquid control valve is mounted between an outer cylindrical body member and the valve body member and comprises a diaphragm of elastomeric material mounted on the outer cylindrical body member and having a central opening engaging the valve body member.

Abstract: Bottle filling means suitable for filling a bottle with aerated or sparkling liquid, (for example sparkling wine) contained in a bowl at superatmospheric pressure, comprising a float valve in the bowl which establishes a liquid level therein, at least two valves carried by the bowl and operated by a cam track engaged by the valves upon rotation of the bowl, a first valve being a liquid flow valve, opening to initiate a syphon action of the liquid from the bowl into the bottle through a syphon tube depending from the valve, a second valve, a bottle venting valve, opening to vent displaced air and gas from the bottle as it is filled, the bottle venting valve being connected to a flow meter which regulates rate of release of gas to atmosphere, so that the bottle fills rapidly but with a minimum of turbulence, a minimum of loss of carbon dioxide gas, and a minimum of oxidation due to the air contained in the bottle.
