<p><P>PROBLEM TO BE SOLVED: To provide a single screw compressor capable of remarkably reducing the noise generated by overlapping of pressure pulsations one over another. <P>SOLUTION: The single screw compressor 1 includes a screw rotor 3 having a plurality of spiral grooves 22 at the periphery of a first rotary shaft 8, and gate rotors 5 and 6 having a plurality of teeth 12 at the periphery of second rotary shafts 8 and 9. The ratios of the number of grooves 11 in a screw rotor 2 to the numbers of teeth 12 of the gate rotors 5 and 6 are not coprime. Adjoining gate rotors have different tooth shapes. The grooves 11 in the screw rotor 2 have such a shape as to mesh with the teeth 12 of the gate rotors 5 and 6. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
