Abstract: A system for use in a pressurized atmosphere or medium includes a shaft housing (56), a shaft (54) rotatably accommodated within the shaft housing (56), and a pressure compensator (2) for transferring a first compensation pressure (P1) via a pressure fluid (6) to a first space. The shaft (54) and shaft housing (56) jointly define a shaft compartment (58), wherein at least three bearing seals (531, 532, 533) are provided between the shaft (54) and the shaft housing (56) positioned at different axial positions along the shaft (54).The bearing seals (531, 532, 533) shield the shaft compartment (56) with respect to an environment having an ambient pressure (P0), creating a first space (41) between a first and second bearing seals (531, 532) and a second space (42) between the second and third bearing seals (532, 533). The pressure compensator (2) comprises a reservoir (5) with a variable internal volume which is arranged to contain the pressure fluid (6) and is influenced by ambient pressure (P0). The pressure compensator (2) comprises a first supply pipe (32), being in fluid communication with the reservoir (5) and the first supply pipe (32) being connectable to the first space. The pressure compensator comprises a second supply pipe (36) being in fluid communication with the reservoir (5) and being connectable to a second space for transferring a second compensation pressure (P2) to a second space. The second supply pipe (36) comprises a pressure resistance or pressure regulating device (38) positioned in the second supply pipe (36). The first supply pipe (32) is in fluid communication with the first space (41) and the second supply pipe (36) is in fluid communication with the second space (42).
