Abstract
A rotary compressor is provided. The rotary compressor may include a plurality of cylinders each having a suction port formed such that an intersection of a center line of the suction port and a center line of a vane slot is positioned at a predetermined interval closer to the vane slot than to an intersection between a center of an inner diameter of the cylinder and the center line of the vane slot. A proximal end of the suction port may be formed in the vicinity of the vane slot so as to advance a compression start angle of a compression space and reduce a dead volume between the vane slot and the suction port, thus improving compressor performance.
