Abstract
A rotary compressor includes a cylinder that is coupled to an inner space of a casing and that defines a compression space, a first bearing and a second bearing located at upper and lower sides of the cylinder, a roller disposed eccentrically with respect to an inner circumferential surface of the cylinder to vary a volume of the compression space based on rotation, and a vane inserted into the roller to rotate together with the roller, and drawn out toward the inner circumferential surface of the cylinder during the rotation of the roller to partition the compression space into a plurality of compression chambers. A suction passage communicating with the compression space is defined in the first bearing or the second bearing, and a suction port communicating between the suction passage and the compression space is defined on a side surface of the cylinder.
