Abstract: The invention provides a metal bellows type accumulator having an outer shell provided in its one end with a pressure introducing passage in an opening manner, an axially expandable metal bellows including peak portions directed to an outer side in a radial direction and trough portions directed to an inner side alternately in an axial direction, having an axially fixed end to the outer shell and separating an inner chamber of the outer shell into a pressure introducing chamber and a gas chamber charged with cushion gas, and a support member arranged in an inner periphery of the metal bellows, fixed to the outer shell and constructed by a cushioning member. A clearance in a radial direction between the trough portions of the metal bellows and the support member is smaller than a clearance in a radial direction between the peak portions of the metal bellows and the outer shell.

Abstract: An accumulator has a seal member retained to a port hole side of a bellows cap via a seal holder. The seal member comes into contact with a seal portion so as to occlude a liquid chamber in the case that an operation of a device stops and the pressure within a pressure piping is lowered. The seal member moves in a direction that the bellows cap moves away from the seal portion while being in contact with the seal portion when the liquid confined in the liquid chamber thermally expands in a state in which the liquid chamber is occluded. The seal member is obtained by attaching a flexible portion constructed by a rubber-like elastic body to an outer peripheral surface of a rigid plate, and the flexible portion allows relative movement of the bellows cap by shear deformation on the basis of engagement with the seal holder.
