Rotary compressor

A rotary compressor, comprising:

• a first cylinder, comprising:
• a first compression chamber, a first suction port communicatively coupled with the first compression chamber, and a first vane slot on one side of the first suction port;
• a first roller rotatably supported in the first compression chamber;
• a first vane slidably disposed in the first vane slot, and contacting an outer circumferential surface of the first roller;
• a second cylinder disposed on one axial side of the first cylinder, and forming a second compression chamber separated from the first compression chamber, the second cylinder comprising:
• a second suction port communicatively coupled with the second compression chamber, and a second vane slot on one side of the second suction port;
• a second roller rotatably supported in the second compression chamber;
• a second vane slidably disposed in the second vane slot, and contacting an outer circumferential surface of the second roller;
• and an intermediate plate disposed between the first cylinder and the second cylinder, separating the first compression chamber and the second compression chamber, and formed with a suction passage configured for connection to a suction pipe, the suction passage being communicatively coupled with the first suction port and the second suction port, wherein at least one of the first suction port or the second suction port fluidly connects an inner circumferential surface of the respective first or second cylinder and at least one axial side surface of the respective first or second cylinder in contact with the intermediate plate, wherein a first partition wall portion is formed between the first suction port and the first vane slot and a second partition wall portion is formed between the second suction port and the second vane, wherein the first suction port has an asymmetric shape, the first suction port having a cross sectional area closer to the first vane slot with respect to a radial center line of the first suction port that is larger than a cross sectional area disposed on an opposite side of the radial center line from the first vane.
