<p><P>PROBLEM TO BE SOLVED: To provide a bellows type accumulator avoiding excessive stress due to stress concentration to a cap and trough portions of bellows positioned adjacently to the cap, and stress concentration to a near-welding portion between the bellows and the cap, in a 0-down state in which the bellows are contracted; and improving the durability of the bellows. <P>SOLUTION: The bellows type accumulator is composed of a shell; the bellows disposed in the shell, fixed on the shell side at one end, and blocked by the cap at the other end to separate a gas chamber and a liquid chamber in the shell; and a ring held on the outer periphery side of the cap and the bellows so as to clip those. The wall thickness of claw portions fitted in trough portions of the bellows of the ring is within a range of 70-100% to trough width dimensions in an axial direction of the bellows in a natural state. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
