<p><P>PROBLEM TO BE SOLVED: To provide an accumulator which maintains excellent buffering performance without escape of gas in a gas chamber, even when left as it is in a low-temperature or high-temperature atmosphere for a long period. <P>SOLUTION: In the accumulator comprising: a shell; a lid member fixed by caulking to the shell; and a bladder made of a rubbery elastic material arranged in the shell, whose opening part is held fluid-tightly near an opening part of the shell, compressed gas is sealed in the gas chamber enclosed by the shell and the bladder, and liquid is introduced into a liquid chamber enclosed by the lid member and the bladder from the outside through a liquid introduction hole provided in the lid member. The accumulator is characterized as follows: a stage part is provided near the opening part of the shell; a ring-shaped mounting flange part is provided on the opening part of the bladder; a step part corresponding to the stage part is formed on the mounting flange part; and a ring shaped gasket comprising a rubbery elastic material having more excellent temperature characteristic than the bladder is arranged between the stage part and the step part. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
