Vane type rotary compressor with rotary sleeve |
摘要 |
A rotary compressor provided with a center housing and side housings, a rotary sleeve mounted for rotation in the housings and a plurality of vanes radially, slidably fitted in a rotor which is eccentrically disposed in the rotary sleeve. The rotary sleeve has its opposite side surfaces formed with a plurality of air-guide grooves. As the rotary sleeve rotates, the air-guide grooves guide air to flow from the compression working space in the rotary sleeve to the air-bearing room between the outer periphery of the rotary sleeve and the inner periphery of the center housing and from the air-bearing room to the suction working space in the rotary sleeve so that an air film is formed in each of the both side clearances between the both side surfaces of the rotary sleeve and the inner surfaces of both side housings.
