Abstract
A rotary compressor is provided that may include a cylinder having an inner circumferential surface with an annular shape to form a compression space; a roller having a plurality of vane slots disposed at predetermined intervals along an outer circumferential surface thereof, and rotatably inserted into the compression space of the cylinder; and a plurality of vanes slidably inserted into the respective vane slots to rotate together with the roller and by which the compression space is divided into a plurality of compression chambers. At least one of the vane slots is unequally spaced in a circumferential direction. Accordingly, periodicity of noise may be reduced to thereby increase the effect of noise reduction of the compressor.
