摘要： The present invention provides a screw compressor that can reduce leakage on the high pressure side and reduce the thrust load. A screw compressor (1) comprises a screw rotor (2, 52) and a plurality of gate rotors (5a, 5b, 5c, 5d) . The screw rotor (2, 52) has helical grooves (11a, 11b) in its outer circumferential surface, and is rotatable. In the gate rotors (5a, 5b, 5c, 5d) , a plurality of teeth (12) that meshes with the grooves (11a, 11b) of the screw rotor (2, 52) is radially disposed. The helical grooves (11a, 11b ) comprise: a first screw groove (11a), which compresses a fluid from one end side of the screw rotor (2, 52) to an other end side of the screw rotor (2, 52); and a second screw groove (11b) , which compresses the fluid from the other end side of the screw rotor (2, 52) to the one end side of the screw rotor (2, 52).

摘要： A screw compressor is capable of reducing gas leakage from a space between neighboring tooth portions of the gate rotor so that the compression performance can be improved. A seal portion 5 is placed on the other surface 32 side of the gate rotor 3. The seal portion 5 blocks the space between neighboring tooth portions of the gate rotor.
