Abstract (en)

[origin: EP3418583A1] Provided is an accumulator having excellent sealing performance at a joint between bladders. An accumulator 10 is configured such that a bladder 30 is disposed on the inside of a shell 20 to divide an internal space of the shell 20 into a gas chamber G and a liquid chamber R. The bladder 30 includes an outer-diameter-side bladder 31 having a peripheral edge portion 31a disposed on an inner peripheral portion 20b of the shell 20, and an inner-diameter-side bladder 32 disposed on the inside of the outer-diameter-side bladder 31 and having a peripheral edge portion 32a formed to protrude toward an inner diameter side. The accumulator 10 includes a holder 40 configured to face the inner peripheral portion 20b of the shell 20 to hold, from the inner diameter side, the peripheral edge portion 31a of the outer-diameter-side bladder 31 and the peripheral edge portion 32a of the inner-diameter-side bladder 32. The peripheral edge portion 31a of the outer-diameter-side bladder 31 includes, on an outer diameter side thereof, an outer annular protrusion 31g, and the peripheral edge portion 32a of the inner-diameter-side bladder 32 includes, on the inner diameter side thereof, an inner annular protrusion 32h configured to contact the holder 40.
