<P>PROBLEM TO BE SOLVED: To prevent a fluid from residing inside an accumulator for a long period of time. <P>SOLUTION: The accumulator is provided with: a first cylinder body 20 provided with an inlet port 35 on one end; a second cylinder body 21 having one end fitted to the other end of the first cylinder body 20 slidably in an axis X direction and provided with an outlet port 36 on the other end; a biased part 24c for receiving biasing force so as to be shortened/slid in a direction where one end of the first cylinder body 20 approaches the other end of the second cylinder body 21; and a pressure-receiving part 24e for receiving a pressure from the fluid passing through a flow passage R in the first cylinder body 20 and the second cylinder body 21 so as to be elongated/slid in a direction where one end of the first cylinder body 20 is separated from the other end of the second cylinder body 21. The fluid flows in from the inlet port 35 on one end side of the first cylinder body 20 and flows out from the outlet port 36 on the other end side of the second cylinder body 21. <P>COPYRIGHT: (C)2008,JPO&INPIT |
