Abstract

A compressor is provided in which a rotary member suspended on a stationary member is rotated to compress a refrigerant. The rotary member is suspended on a first stationary member and rotatably supported on a second stationary member spaced apart from the first stationary member, to thereby achieve structural stability, improve operation reliability, and reduce vibration. The components can be easily centered and assembled with an excellent assembly property. In addition, a mounting structure of an elastically-supported vane is improved to ensure lubrication performance and operation reliability. Moreover, a mounting structure of a roller-incorporated vane is improved to reduce vibration and prevent refrigerant leakage, which leads to high compression efficiency.
