Abstract: A beverage dispensing device using a pressure regulator to maintain the pressure inside the beverage container as the beverage is dispensed is disclosed. The pressure regulator includes a second chamber separate from the space containing the beverage. The second chamber contains a sorbent on which a propellant gas is adsorbed. The pressure inside the beverage container controls the opening and closing of a flow regulator that allows either the beverage being dispensed or a displacing agent contained in a third chamber to flow into the second chamber when the pressure in the beverage container is decreased. If either the beverage or the displacing agent flow into the second chamber, it will liberate the propellant gas adsorbed to the sorbent, and the gas is released through an outlet into the beverage container. This increases the pressure in the beverage, which in turn closes the flow regulator and stops the liberation of the propellant gas from the sorbent.

Abstract: A home beer dispensing apparatus has a keg having a self-contained bag filled with a beer and a pressure system. The pressure system creates a pressurized air space between the keg inner walls and the bag to assist in the dispensing of the beer. The pressure system has a keg one-way air valve mounted to a top wall of the keg to permit entry of pressurized air into the keg. The pressure system has a pressure reservoir mounted in the dispensing apparatus outside the keg and in fluid flow communication with the keg one-way valve. The reservoir stores a charge of pressurized air and supplies at least a portion of this charge to the keg through the keg air valve when the dispensing apparatus is operated to dispense the beer. The reservoir provides a reserved charge of pressurized gas that is on hand to reduce dampening pressure fluctuations during beer dispensing which can result in beer frothing, especially during the early stages of beer dispensing when the air head space in the keg is small.
