    摘要： An outer gas type or inner gas type accumulator has a mechanism for reducing a pressure difference generated when liquid in a liquid chamber and gas expand thermally at a zero-down time, the pressure difference between the inside and outside of a bellows is reduced to suppress abnormal deformation of the bellows, a movable plate supported by a spring is provided at the bellows cap side of an oil port, the movable plate is supported by the spring and away from a seal in normal operation, the movable plate is pushed by the bellows cap and contacts with the seal while elastically deforming the spring, in a zero-down state, and when the liquid and the gas expand thermally in the zero-down state, the bellows cap moves to a position where the liquid pressure and the gas pressure balance, while the movable plate keeps contact with the seal.

    摘要： To prevent abnormal deformation of a bellows, an accumulator has a regulation mechanism for reducing a pressure difference generated when liquid sealed in a liquid chamber and charged gas are thermally expanded at a zero-down time, a seal plate is arranged in an inner peripheral side of a bellows floating end, an elastically deformable thin plate is bonded to the seal plate, an outer peripheral portion of the thin plate is bonded to the bellows floating end, the seal plate is away from a seal at a time of a steady operation, the seal plate contacts with the seal at a zero-down time, and the thin plate is elastically deformed to make liquid pressure balance with gas pressure while the seal plate being kept in contact with the seal when the liquid and gas are thermally expanded.
