Rotary sleeve of a rotary compressor |
摘要 |
The rotary compressor according to the present invention is constructed such that a rotary sleeve is rotatably floating, and suspended within a central housing by means of a pneumatic bearing chamber. A rotor, whose vane can move freely into and out of said rotor is rotatably housed in said rotary sleeve. The outside surface of said rotary sleeve is formed like a barrel, whose radius diminishes axially from the midpoint toward both ends. The inside surface of said central housing spacedly follows the outside surface of said rotary sleeve. Under this construction the rotary sleeve can be automatically adjusted and stabilized in position within the central housing in both the axial and the oscillating directions. Also under this construction which prevents contact between the rotary sleeve and the central housing, wear, scuffing or seizure can be avoided even if the rotary sleeve in thermally deformed and bent outwardly at both ends.
