Abstract:
A hermetically sealed pressure-balanced accumulator includes a housing and a moveable divider mechanism for separating the housing into at least an accumulator chamber at a pre-selected accumulator pressure. A first balancing chamber is responsive to changes in ambient pressure for adjusting said pre-selected accumulator pressure with respect to ambient pressure. A second balancing chamber is responsive to the first balancing chamber, and the first and second balancing chambers maintain a predetermined pressure differential between the pre-selected accumulator pressure and ambient pressure. The hermetically sealed pressure-balanced accumulator further includes a hermetic sealing device for sealing the first balancing chamber from at least one of the accumulator chamber and the second balancing chamber.
