Abstract:
The purpose of the present application is to provide an accumulator that can reduce the number of components in a pressure fluctuation absorbing mechanism, simplify assembly, and reduce component costs. An accumulator (1) comprises: a pressure vessel (2); a partitioning part (11) that partitions an internal space of the pressure vessel (2) into a gas chamber (9) that is filled with a gas and a liquid chamber (10) into which a liquid is introduced; and bellows (7) that are connected to the partitioning part (11). The partitioning part (11) comprises: a bellows connection part (12) that is connected to the bellows (7); a seal (15) that is disposed on a liquid-chamber-side of the bellows connection part (12); and a seal-holding part (14) that is fixed to the bellows connection part (12) and holds the seal (15). The seal-holding part (14) comprises a plate spring, part of which can elastically deform, and is configured such that a fixed part (17) that is fixed to the bellows connection part (12) and a holding part (16) that holds the seal are integrally formed.
