Abstract

PURPOSE: To prevent contact between slide valve and rotor by setting the ratio between the slide valve diameter and outer diameter of the rotor to 0.65 to 0.74 and setting the angle of the intersection between the circule of the slide valve chamber and rotor chamber to 23°W27°.
CONSTITUTION: The ratio between the diameter (d) of a slide valve 15 and the outer diameter of a rotor 1 is set to 0.65 to 0.75, and the angle θ between the straight line l3 passing through the center of the slide valve 15 and the straight line l4 connecting the intersection between the circle of the rotor chamber and the circle of the slide valve 15 and the center of the slide valve 15 is set to 23°W27°. With this arrangement, the distance of movement of the slide valve 15 toward the rotor 1 can be reduced, and thus it is possible to prevent the contact between the slide valve 15 and rotor 1.
