ABSTRACT:
A pressure compensating enclosure comprises a sealed enclosure having substantially rigid outer walls and an interior cavity adapted to receive components to be protected by the enclosure. The sealed enclosure has an aperture in one of its outer walls which is sealingly coupled to a hollow, elastic member disposed in the enclosure so as to be in fluid communication with the exterior of the enclosure. An incompressible fluid substantially fills the sealed enclosure, wherein in response to a change in temperature of the enclosure, the volume occupied by the incompressible fluid changes and the hollow elastic member deforms responsive to the change in volume of the incompressible fluid sufficient to pressure balance the enclosure.
