<p>PURPOSE:To prevent a leak of gas, by eliminating the sealing part in an atmospheric side. CONSTITUTION:An accumulator constitutes an integrally formed cylindrical pressure vessel 1 blocking its one end and opening the other end. A piston 2 is slidably provided in this pressure vessel 1. While a cap 4, closing an opening part of the pressure vessel 1, provides a valve seat 2a for charging the vessel with gas. Further the pressure vessel 1 is divided into two chambers by the piston 2, and one of the chambers is filled with inert gas 8 through a gas sealing port. While the chamber in a side of the cap 4 is filled with working fluid 9. By this constitution, the accumulator, enabling the sealing part in an atmospheric side to be eliminated further with the high pressure working fluid existing in a condition holding pressure balance in a leaking route of gas, can prevent the gas from leaking.</p> |
