る構成にした速度制御装置。A pilot-operated linear control valve that is installed in the drive circuit that connects the pump and motor and changes the opening area of the port depending on the switching amount, and a proportional pressure control valve that is connected to the pump or a pressure source separate from the pump. and,
A solenoid switching valve is provided on the downstream side of the proportional pressure control valve and guides the pressure flowing out from the proportional pressure control valve to the pilot chamber of either one of the linear control valves, and is set by the proportional pressure control valve. A speed control device configured to adjust the switching amount of the linear control valve using the pilot pressure generated.
