Abstract
A filling valve for filling a container from a pressurized liquid filled bowl is disclosed. The filling valve includes a housing with a liquid filling orifice through it and a liquid flow valve for opening and closing that orifice. A gas flow tube extends through the liquid flow valve element and projects both above and below it. A pressure responsive piston is supported on the gas flow tube. A cover is located over the gas flow opening at the top of the gas flow tube and includes a closure element ball. A sleeve supports the closure element above the top opening of the tube. A spring holds the closure element off the top opening of the tube. A guide sleeve outside the supporting sleeve is connected with the gas flow tube. A spring biases the supporting sleeve out of the guide sleeve. A cam has one orientation at which it closes both the gas flow tube and the liquid flow valve element and a second orientation at which the cam permits both of the supporting sleeve and the guide sleeve to rise under the influence of the respective springs acting on them, for selectively opening the gas flow tube and the liquid flow valve. A sudden pressure differential along the gas flow tube, due to…
