    Abstract: An apparatus disposed within a pressurized container for enabling product contained in the container to be dispensed at a predetermined constant pressure, which apparatus includes a vessel having first and second enclosures housing pressurized gas and a member exposed to the pressure in the container. Fluctuations of the pressure in the container cause the member to move to a first position when the pressure in the container equals the predetermined pressure and to a second position when the pressure in the container is below the predetermined pressure. Pressurized gas passes from the first enclosure to the container when the member moves to the second position, the passage of which is prevented when the member moves back to the first position.
