ABSTRACT:
A rotary compressor with a center housing and a rotary sleeve mounted in the 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 to floatingly support the rotary sleeve, characterized in that a part of compressed air in the rotary compressor is injected into the air-bearing room through the throttles provided in the compression side wall of the center housing to prevent the rotary sleeve from scuffing the inner periphery of the center housing.
