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. |

1. A compressor, comprising;
a hermetic container into and from which a refrigerant is sucked and discharged; a stator fixed to an inner surface of the hermetic container; a first stationary member including a stationary shaft having a first end immovably installed in a first portion of the hermetic container and being elongated in the hermetic container and an eccentric pardon eccentric from a center of the stationary shaft; a second stationary member spaced apart from a second end of the first stationary member and immovably installed in a second portion of the hermetic container; and a rotary member located inside the stator, including a cylinder-type rotor rotated around the stationary shaft by a rotating electromagnetic field from the stator, a roller applied with a rotational force of the cylinder-type rotor, rotated around the eccentric portion with the cylinder-type rotor, a compression space being defined between the roller and the cylinder-type rotor, a vane fixedly formed on the roller to protrude from an outer circumferential surface of the roller to the cylinder-type rotor, transfer the rotational force from the cylinder-type rotor to the roller, and partition the compression space into a suction pocket, into which the refrigerant is sucked, and a compression pocket, into and from which the refrigerant is compressed and discharged, and first and second bearing covers that form first and second portions of the compression space and rotate around the first stationary member with the cylinder, wherein a vane mounting hole is provided in the cylinder-type rotor to accommodate the protruding vane, and wherein the rotary member is rotatably supported by applying a load to the second stationary member. |
