A speed controller detects the rotational speed and increases the opening of the first flow rate control valve when the rotational speed decreases, and medium pressure gas can be supplied to the middle part of the rotor chamber, which is the storage space of the screw rotor, through the flow rate control valve. and an intermediate pressure gas supply line configured to increase the opening degree of the second flow rate control valve as the rotation speed of the screw rotor decreases and the speed controller reduces the rotational speed of the screw rotor after the first flow rate control valve is fully opened. Screw expansion machine.
