Abstract

A control device prevents rapid changes in an internal pressure of an enclosed space induced by an external environment. The control device includes a first pressure sensor in the enclosed space, a second pressure sensor outside the enclosed space, a pressurized container and a vacuum container in the enclosed space and a regulator to at least partially compensate for rapid pressure changes in the enclosed space detected in response to signals generated by the first and second pressure sensors. If the detected rapid pressure change is a decrease in the internal pressure in the enclosed space, the regulator controls the pressurized container to provide a controlled supply of air and if the detected rapid pressure change is an increase in the internal pressure in the enclosed space, the regulator controls the vacuum container to remove of air from the enclosed space.
