摘要：Problem to be solved: to provide a working machine capable of regenerating areturn pressure oil from a hydraulic actuator, and for preventing the reduction of thedrag loss of the regenerative hydraulic motor and the hydraulic pump, and theregeneration efficiency of the regenerative hydraulic motor. The controller 100calculates the rotational speed of the regenerative hydraulic motor required from thevolume of the regenerative hydraulic motor 13 and the regenerative flow rate of theregenerative hydraulic motor, and calculates the first hydraulic pump rotational speedfrom the volume of the first hydraulic pump 15 and the target assist flow rate of the firsthydraulic pump, and the regeneration of the first hydraulic pump required The value ofthe number of revolutions of the hydraulic motor and the number of revolutions of thefirst hydraulic pump required rotation is set to the target rotational speed of the motor
