Abstract
In a screw compressor, a pair of rotors are located in a housing to be rotatable around their rotary axes to form in the housing a compression chamber in which gas sucked from a suction port of the housing is compressed thereby discharging the compressed gas from a discharge port of the housing. The suction port is provided in the housing at a position radial outside of the rotors, and the housing is provided with a communication passage through which the suction port communicates with the compression chamber before being communicated with the suction port. Furthermore, the communication passage is provided such that the gas sucked from the suction port flows into the communication passage in a direction approximately parallel with an axial direction of the rotors.
