ABSTRACT:
First and second displacement variable regenerating hydraulic motors are provided in third and fourth flow rate control lines which function as discharge flow paths for oil discharged, respectively, from first and second oil supply and discharge ports of a hydraulic motor, where controlling the displacement of the regenerating hydraulic motors allows the flow rate of discharge oil as well as the pressure of the third and fourth flow rate control lines to be controlled. First and second generators which generate electric power due to the rotation of the first and second regenerating hydraulic motors are further provided.
