A method for preventing gas flow into and out of a first enclosure having a first volume by limiting changes of the pressure within the first enclosure which includes providing a second enclosure including a variable volume device having an interior second volume that varies responsive to the pressures inside and outside the second enclosure and providing fluid communication between the interior of the first enclosure and the interior of the second enclosure to maintain a substantially fixed collective volume of the combination of the first enclosure and the second enclosure despite ambient temperature.
