<P>PROBLEM TO BE SOLVED: To provide an accumulator in which a direct relief function on a liquid chamber can be set or a direct relief function on a gas chamber cannot be set, options are presented in designing the above function, and wide flexibility is given to designing. <P>SOLUTION: The accumulator includes: an oil port having a through-hole type liquid inlet hole; a shell combined with the oil port to form together with the oil port an accumulator housing ; a bellows and a bellows cap assembled inside the housing and partitioning the inside of the housing into a liquid chamber communicates with the liquid inlet hole and a gas chamber for sealing a high pressure gas; and a sealing part for sealing between the liquid chamber and the liquid inlet hole when the bellows cap reaches a stroke limit on the oil port side. The oil port includes a pressure relief mechanism, which opens a valve or fractures to release pressure when the pressure in the gas chamber or in the liquid chamber reaches a predetermined value or higher. <P>COPYRIGHT: (C)2012,JPO&INPIT |
