<p>PROBLEM TO BE SOLVED: To enable the direct connection of an accumulator to a pipeline, and secure the durability thereof against the sudden fluid pressure by providing a main body having a communication chamber between both pipeline joints, and providing a restriction through passage for fluid in impact pressure absorbing plates provided for partitioning in the communication chamber. SOLUTION: An accumulator main body 2 is formed with a flange 3 in on both ends thereof, and both the ends 5, which are arranged on both sides of a cylindrical part 4, are caulked for integration by bolts 11. The main body 2 is provided with a communication chamber 9 between passages 8a, 8b formed on both the ends 5. Impact absorbing plates 6, 6 are fixed to the main body 2 in parallel with each other so as to partition the communication chamber 9 and so as to seal the communication chamber 9. The impact absorbing plate 6 is formed of a rubber plate or a metal plate or the like, and formed with a through passage 12 at a central part thereof, and a clearance chamber 9a is formed between the impact absorbing plates 6, 6. Impact fluid pressure propagated inside a pipeline 7 is directly received for absorption by the impact absorbing plates 6, and while the impact absorbing plates 6 cooperate with the clearance chamber 9a so as to restrict the influence of the impact pressure to other equipment.</p> |
