Rotary compressor

A rotary compressor includes a cylinder with a vane slot and a suction port. A vane is slidably disposed in the vane slot. The suction port guides fluid to a compression chamber at one circumferential end of the vane slot. The suction port may be formed in a recessed manner in a radial direction suc...

description	A rotary compressor includes a cylinder with a vane slot and a suction port. A vane is slidably disposed in the vane slot. The suction port guides fluid to a compression chamber at one circumferential end of the vane slot. The suction port may be formed in a recessed manner in a radial direction such that at least an end of the suction port in contact with an inner circumferential surface of the cylinder forms a slot shape extending between opposite axial side surfaces of the cylinder. A circumferential length of the suction port is reduced from conventional suction ports as a result of the slot configuration, thereby advancing the compression start angle, and a partition wall portion between the suction port and the vane slot may have elasticity, thereby suppressing close contact between the vane and the vane slot.
