PROBLEM TO BE SOLVED: To provide an active accumulator, which can supply pressure oil, equivalent to the volume of pressure vessel to accumulate pressure oil, to the outside, miniaturize drastically and maintain the constant supply pressure. SOLUTION: This active accumulator consists of the hollow pressure vessel 2 whose lower part is connected to a pressure oil supply line 1, a gas supply line 4 to supply predetermined lower limit pressurized gas to the upper part of the pressure vessel, an exhaust line 6 to exhaust predetermined upper limit pressurized gas from the upper part of the pressure vessel, a level detector 8 to detect the upper and lower limit of pressure oil in the pressure vessel and a level control device 10 to close the exhaust line at the upper limit of pressure oil level. |
