<p><P>PROBLEM TO BE SOLVED: To restrain discharge pulsation and a torque variation in a screw compressor. <P>SOLUTION: This screw compressor 1 has a screw rotor 40 forming a plurality of spiral grooves 41, 41, etc. and a plurality of gate rotors 50A and 50B having gates 51, 51, etc. meshing with the spiral grooves 41, 41, etc. The screw compressor 1 compresses gas by a plurality of compression spaces 23, 23, etc. formed of the spiral grooves 41, 41, etc. and the gates 51, 51, etc., and discharges a refrigerant from a plurality of discharge ports 73 and 73 arranged at each gate rotor 50A and 50B. At this time, timings for discharging the refrigerant from the plurality of discharge ports 73 and 73 are displaced from each other. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
