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 to form a contact point forming a predetermined gap with the cylinder 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 each vane coming into contact with an inner peripheral surface of the cylinder to separate the compression space into a plurality of regions. The at least one vane may include a pin that extends upward or downward, and a lower surface of the first bearing or an upper surface of the second bearing may include a rail groove into which the pin may be inserted.
