WIPO Patent Application WO/2023/176517

A1

A suction flow path of a screw compressor according to the present invention comprises: a male-side flow path opening in an axial direction to a working chamber of the suction stroke of a male rotor 2 side and extending from a starting end on one side of a virtual plane to a first termination end on the other side; and a female-side flow path opening in the axial direction to a working chamber of the suction stroke of a female rotor side and extending from a starting end to a second terminal end on the other side of the virtual plane. A flow path wall of the male-side flow path includes a male-side first flow path wall facing a rotor tooth section side, and a flow path wall of the female-side flow path includes a female-side first flow path facing the rotor tooth section side. The male-side first flow path wall or the female-side first flow path wall approaches the male-side rotor tooth section or the female-side rotor tooth section moving from the starting end side to the first termination end side or the second termination end side in at least a partial section from the starting end to the first termination end or the second termination end.
