摘要： A screw compressor includes a screw rotor, a gate rotor and an injection mechanism. The screw rotor is provided with multiple helical grooves. The gate rotor is provided with multiple gates meshing with the helical grooves to form at least one compression chamber between at least one of the helical grooves and at least one of the gates. The compression chamber is configured and arranged such that refrigerant taken-in from a starting-end side of the helical groove is compressed and discharged from a dead-end side of the helical groove. The injection mechanism is configured and arranged to inject oil or refrigerant from a discharge hole of the injection mechanism into the compression chamber such that rotational torque is imparted in a direction in which the screw rotor is rotated at a time of compression.

摘要： An inner ring is shaped in its contour by a cold-shaping treatment and is hardened on its surface by a nitrosulphurizing treatment or a soft-nitriding treatment. As a result, the hardness of the surface of the inner ring is enhanced by the cold-shaping treatment and further by the subsequent hardening treatment. As a result, the inner ring is improved in its wear resistance and its seizure resistance. Moreover, the hardening treatment is effected by the nitrosulphurizing treatment or the soft-nitriding treatment so that it can be suppressed from straining in that treating procedure.
