Abstract
PURPOSE: To enable single-piece working and to facilitate the optimized design by providing, on an exterior discharge sidewall of the casing, guide pieces which rub with projected angular surface of a slide valve of a screw rotor interlocking, and limit shapes of discharging ports.
CONSTITUTION: A slide valve 8 for capacity regulation that moves to a direction of a rotor shaft, is provided on one side of interlocking of one pair (male and female) of screw rotors 5 and 6 which are housed in a rotor casing 1. Guide pieces 12 and 13 which contact with concave arcuate sphere 8b and limit shape of a discharging port 11 are provided on an enternal discharge sidewall of the casing 1a. Then, by keeping the distance between guide pieces 12 and 13 and the centers of rotors 01 and 02 slightly larger than the size of the rotors, with the clearance of ε1 and ε2, the rotors 5 and 6, and the slide valve 8 are free from contacting. Therefore, the slide valve 8 gets secured support and, slide valves of any desired discharging ports can be assembled by single-piece working. This in turn enables to design optimized compressors with ease.
