<p><P>PROBLEM TO BE SOLVED: To provide a piston type accumulator which has a simple construction, hardly contaminates under several kinds of used conditions, and has high functionability. <P>SOLUTION: The piston type accumulator is provided with an outer case 1, a piston 2 slidably fitted in the outer case 1, demarcating an outer case 1 inside into a liquid chamber 3 and a gas chamber 4, a liquid sealing means 9 arranged in a liquid chamber 3 side of the piston 2 periphery, a gas sealing means 10 arranged in a gas chamber 4 side of the piston 2 periphery, and a partition chamber 5 comprised of the outer case 1 inside, the outer case 2 outside, the liquid sealing means 9 and the gas sealing means 10. A purge inlet 6 and a purge outlet 7 to purge the partition chamber 5 are provided to detect the pressure in the partition chamber 5 of the introduced purge fluid and control so as to maintain the pressure lower than at least either of the liquid chamber 3 or the gas chamber 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
