  • Publication number: 20120128511
    Abstract: The present invention relates to a compressor in which a rotary member suspended on a stationary member is rotated to compress the 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 the structural stability, improve the operation reliability and reduce the 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 the lubrication performance and the 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.
