とする液圧再生回路。The hydraulic actuator is driven by pressure oil supplied through the control valve and the counterbalance valve in this order, and at this time, the oil pushed out from the hydraulic actuator is discharged through the counterbalance valve and the control valve in this order. In this circuit, a pressure accumulator and a control valve operated by the pilot pressure of the counterbalance valve are provided, and when the hydraulic actuator brakes, oil pushed out from the hydraulic actuator is transferred to the pressure accumulator via the control valve. A hydraulic regeneration circuit characterized in that the oil stored in the pressure accumulator is supplied to the actuator via the control valve when the hydraulic actuator is driven.
