Pressure compensator and method of manufacturing a pressure compensator

摘要

PRESSURE COMPENSATOR AND METHOD OF MANUFACTURING A PRESSURE COMPENSATOR A pressure compensator (100) for providing pressure compensation for a subsea device is provided. The pressure compensator (100) has a compensator wall enclosing a compensation chamber (20) and at least one bellows assembly (11). The bellows assembly (11) includes a metal bellows (15) that forms part of the compensator wall (10). The metal bellows (15) is deformable to change the inner volume of the compensation chamber (20). The bellows assembly (11) further includes an elastomeric bellows (16) provided on the compensator wall (10) and covering at least the metal bellows (15). A seal seals the space between the metal bellows (15) and the elastomeric bellows (16). The space between the metal bellows (15) and the elastomeric bellows (16) is provided with a vacuum. 11{ 17 15, 16 21 { 25, 26 19 219 201 101
