<p><P>PROBLEM TO BE SOLVED: To provide an accumulator provided with structure capable of securing high responsiveness to a small change of volume and improved in durability of a bladder itself. <P>SOLUTION: This accumulator 1 is provided with a free piston 3 slidably housed inside a cylinder 2 to divide the inside of the cylinder 2 into a gas chamber A and a liquid chamber O and the bladder 4 provided on the liquid chamber O side of the free piston 3. A bladder chamber B surrounded by the bladder 4 and the free piston 3 is communicated with the gas chamber A through a communication hole provided in the free piston 3, and the communication hole is provided with an orifice 5 for regulating deformation quantity of the bladder when volume of the liquid chamber is changed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
