Rotary-sleeve bearing apparatus for rotary compressor |
摘要 |
An air-bearing apparatus for use in a movable vane compressor of the type having a rotary sleeve mounted in the center housing for rotation with a plurality of vanes, said apparatus comprising an air-bearing room defined between the inner periphery of the center housing and the outer periphery of the rotary sleeve to floatingly support the rotary sleeve and an air-supply passage to supply air to the air-bearing room from the compression-working space. In order to increase the bearing performance of the air-bearing room when the compressor runs at high speeds in which the amount of air to be supplied to the air-bearing room exceeds what can be extracted from the compression-working space, the apparatus is provided with an auxiliary passage extending from the discharge chamber to the air-supply passage through a check valve to supply air to the air-bearing room from the discharge chamber.
