Abstract

PURPOSE: To decrease power loss of a compressor and to increase efficiency of it, by actually causing neither a compressing action nor a sucking action between the final end of discharge port and the initial point of suction port, by uniforming the clearance between the said section of a rotor and a cam ring.
CONSTITUTION: The radius of a rotor 1 is determined to the maximum as far as the outer circumference of a rotor does not contact to a cam ring 2 on the tangent sealing part, considering the clearance of a radial bearing part, by determining the radius rR of a rotor 1 slightly shorter than rC, as well as connecting the initial point c of a suction port 3 to the final end b of a discharge port 4 by an arc of a circle of which radius from a center o of a rotor 1 is rC. With such an arrangement, the change of pressure to the angle of rotation θ of a rotor is improved and the power as far as corresponding to the part of oblique lines is decreased, so that the efficiency of a compressor can be improved.
