Abstract
A rotary compressor is provided that may include a rotational shaft, first and second bearings configured to support the rotational shaft in a radial direction, a cylinder disposed between the first and second bearings to form a compression space, a rotor disposed in the compression space and coupled to the rotational shaft to compress a refrigerant as the rotor rotates, and at least one vane slidably inserted into the rotor, the at least one vane coming into contact with an inner peripheral surface of the cylinder to separate the compression space into a plurality of regions. At least one of the first bearing and the second bearing may include first and second pockets formed on a surface facing the rotor, and at least one of the first pocket and the second pocket may be formed in an asymmetrical shape.
