(57) Abstract: An accumulator (1) having a housing (2) the interior of which is partitioned into a pressure sealing chamber (8) and a fluid flow-in chamber (9) by disposing an operating member (5) including a bellows (6) in the housing (2), and which is provided with a liquid inlet (14) for introducing fluid to the fluid flow-in chamber (9) from a fluid pipeline, wherein noise due to pulsation wave can be attenuated. A restriction mechanism (20) and a chamber (22) for attenuating noise generated by plusation wave are provided at the idling end of the operating member (5) or at the bellows cap (7) mounted to the end of the bellows (6). <IMAGE> |
