In the accumulator, the accumulator is divided into a control fluid chamber and a control fluid chamber, and absorbs the pulsation by the expansion and contraction action of the compressed gas by reciprocating a movable partition according to the pulsation of the control fluid, and supplying compressed gas to the gas chamber to the accumulator main body. 1. An accumulator, characterized in that the accumulator is provided with a pump means capable of being operatively connected to the movable bulkhead, and is capable of self-filling the gas chamber with gas pressure by driving the pump means with the pulsation of the control fluid. (2) The pump means has a charge chamber equipped with a volume variable means operably connected to the movable partition, and changes the volume of the charge chamber in accordance with the pulsation of the control fluid, thereby increasing the amount of water inside the charge chamber. 2. The accumulator according to claim 1, wherein gas from the outside is sucked and compressed.
