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. This process is repeated as the beverage is being dispensed to maintain the pressure of the beverage inside the dispenser.

What is claimed is: 1. A fluid dispensing device comprising:a. a container defining a first enclosed space for holding a fluid; andb. a pressure regulator in fluid communication with the first enclosed space, the pressure regulator comprising:(i) a second enclosed space;(ii) a sorbent contained within the second enclosed space, the sorbent further comprising a propellant gas adsorbed to the sorbent;(iii) an inlet in fluid communication with the first enclosed space and the second enclosed space;(iv) the inlet comprising a flow regulator wherein the opening and closing of the flow regulator is controlled by the pressure within the first enclosed space; and(v) an outlet in fluid communication with the second enclosed space and the first enclosed space, the outlet including a check valve having a position allowing a flow of propellant gas released from the sorbent from the second enclosed space to the first enclosed space.
