ABSTRACT OF THE DISCLOSURE A rotary compressor of the sliding vane type comprises a cylinder with its top portion where a distance between the outer periphery of the rotor and the inner periphery of the cylinder becomes minimum. An inlet port to a vane chamber is positioned so as to make a(.theta.) almost constant, or meet a(.theta.) = a, in a range of 1/2 .theta.s < .theta. ? .theta.s and parameters of the compressor are determined to meet the following relation; 0.025 <.theta.s a/VO < 0.080 where .theta.(radian): angle from the top portion of the cylinder to the leading end of a vane, which is held in contact with the inner periphery of the cylinder, around the center of revolution of the rotor, .theta.s(radian): angle .theta. at the completion of a suction stroke, VO (cc): volume of the vane chamber when .theta. becomes .theta.s, and a(.theta.)(cm2): effective area of an inlet path from an evaporator to the vane chamber.
