<p>PROBLEM TO BE SOLVED: To always normally operate a bladder, and show preset elimination performance against pulsative motion by arranging projected surfaces projected in the opposite direction to a lid of the bladder, on an opening peripheral surface surrounding a fluid port of a shell. SOLUTION: Operation fluid is flowed from a fluid port 6 of an accumulator 1 and applied to a lid 9 of a bladder 9. The bladder 8 is formed in an inverted manner to a gas chamber 12 by means of projected surfaces 11 at its side of the lid 9. The bladder 8 is thus lifted and separated from an opening peripheral surface 7, and moved while increasing inversion state prepared by the projected surfaces 11, to the side of the gas chamber 12. The operation fluid is then applied to the bladder 8, on its whole surface on the side of a fluid chamber 13. Since the operation fluid is comparatively intensively applied to the lid 9, the bladder 8 can be remarkably shifted to the gas chamber 12 with a normal inversion state of the lid 9. The bladder 8 can thus keep a normally deformed state, show satisfactory responsiveness without strong partial stress, nor any crack.</p> |
