Abstract
A method and apparatus to improve regeneration efficiency when regenerating the energy of discharge fluid from a fluid pressure actuator as electrical energy. In a flow rate control line 15, which finctions as a discharge flow path for oil discharged from a head side oil chamber 1c of a hydraulic cylinder 1, is provided a displacement variable regenerating hydraulic motor 20, where controlling the displacement of the regenerating hydraulic motor 20 allows the flow rate of discharge oil from the hydraulic cylinder head side oil chamber 1c to be controlled. A generator 21, which generates electric power due to the rotation of the regenerating hydraulic motor 20, is further provided.
