Abstract
A device for dispensing liquid from a container includes a dispensing tube to dispense the liquid through a dispensing valve. A gas tube feeds pressurized gas into the container. The upstream end of the gas tube connects to a source of pressurized gas. A three way valve is coupled to the downstream end of the gas tube. The three way valve includes a keg duct in communication with the interior of the container, a gas duct connected to the downstream end of the gas tube, and a vent duct. The three way valve can switch from a dispensing position in which the keg duct is in communication with the gas duct, and out of communication with the vent duct, to a venting position in which the keg duct is in fluid communication with the vent duct and out of fluid communication with the gas duct.
