ABSTRACT:
A rotary compressor provided with a rotary sleeve mounted in a center housing for rotation with a plurality of vanes radially slidably fitted in a rotor which is eccentrically disposed in the rotary sleeve, and an air bearing room defined between the outer periphery of the rotary sleeve and the inner periphery of the center housing and internally connected to compressed air in the compressor, characterized in that a multiplicity of air-accumulating grooves are formed in either or both of the outer periphery of the rotary sleeve and the inner periphery of the center housing to increase the bearing capacity of the air-bearing room and prevent the rotary sleeve from directly contacting the inner periphery of the center housing even if the high-pressure in the rotary sleeve pushes aside the rotary sleeve.
