Abstract

PURPOSE: To maintain high efficiency of a compressor, by separting a delivery side chamber from a suction stroke operating chamber with protrusive edges, forming said edges so as to be alwasy situated in the outside of the periphery of a rotor and preventing communication of the delivery side chamber to the operating chamber.
CONSTITUTION: A curve drawn from a point 51W52 is a part of a circle in larger radius than that of a circle 47 with a point 45 as its center. While a curve drawn from a point 53W54 is a part of a circle in larger radius than that of a circle 46 with a point 44 as its center. There are given a straight line drawn from the point 52W 53 and circular arcs in a small radius drawn from a point 14 to the point 51 and from the point 54W15. Accordingly, a delivery side chamber is never communicated to an operating chamber in a suction stroke, thus high efficiency of a compressor can be always maintained.
