<p>A novel rotary compressor is provided herein. The rotary compressor includes a center housing, a rotary sleeve mounted for rotation in the center housing, a rotor eccentrically disposed in the rotary sleeve, the rotor containing a plurality of vanes radially, movably fitted therein, and an air-bearing room defined between the outer periphery of the rotary sleeve and the inner periphery of the center housing. Preferably, the air bearing room has a radial width of 0.02 to 0.15 mm. The rotary compressor includes a multiplicity of air-accumulating grooves at least on the outer periphery of the rotary sleeve. Preferably, such grooves have a depth of 0.02 to 0.08 mm. Each of the airaccumulating grooves are inclined relative to the peripheral edge of the rotary sleeve, and are provided with at least one dead end. Such air-accumulating grooves are effective to protect the outer periphery of the rotary sleeve from directly containing the inner periphery of the center housing. Also there is no significant possibility of scuffing and seizing between the rotary sleeve and the center housing.</p> |
