In stopping operation of the compressor, on the other hand, compressed air is injected into the screw seal 18 to prevent backflow of oil from the screw seal 18. Further, in full load operation of the compressor, the injection hole 20 is closed so that the shaft is sealed by the sealing function of the screw seal 18 itself. Thus, the rotor shaft can be sealed in a most suited manner according to the operational conditions of the compressor.
