Abstract
A container assembly may include a regulated tank to contain a fluid, a free tank to replenish the fluid in the regulated tank, a first expandable member between an interior of the regulated tank and ambient atmospheric pressure, a second expandable member between the interior of the regulated tank and an inflation port, a first valve to selectively connect the free tank to the regulated tank based upon a pressure differential between the interior of the regulated tank and an interior of the free tank and a second valve actuatable between an open state permitting an interior of the free tank to be pressurized and a closed state. The second valve is actuatable between the open state and the closed state based upon a position of the first expandable member.
