御装置。A slide valve that slides with the rotor in the axial direction of the rotor is provided on one side of the meshing part of the pair of screw rotors housed in the casing, and by sliding the slide valve, the bypass communicates with the gas inlet of the rotor. A screw compressor that changes the discharge gas capacity by opening and closing a passage includes a piston that slides the slide valve, an oil pump that sends oil to the cylinder of the piston, one end of which is connected to the oil pump, and the other end of which is connected to the oil pump. A control device for a screw compressor, comprising a solenoid valve connected to the cylinder and a pressure switch attached near the gas inlet, the solenoid valve being opened and closed by the pressure switch.
