  • Patent number: 9181947
    Abstract: A compressor is provided in which a rotary member suspended on a stationary member is rotated to compress a refrigerant. As 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, components can be easily centered and assembled with structural stability. In addition, oil stored in a hermetic container is supplied to a lubrication passage provided between the rotary member and the stationary member. This reduces friction loss between the components and achieves operational reliability. Moreover, the oil is easily introduced into a vane mounting hole in which a vane is linearly reciprocated. This reduces friction and abrasion of the vane and improves the operational reliability.

  • Patent number: 9097254
    Abstract: A compressor is provided that eliminates sliding contacts between a cylinder and a roller to minimize mixing of lubricating oil into a refrigerant. The compressor includes a hermetic container that stores the lubricating oil at a lower portion thereof; a stator mounted within the hermetic container; a cylinder type rotor that rotates within the stator by a rotating electromagnetic field of the stator and defines a compression chamber therein; a roller that rotates and compresses the refrigerant by a rotational force transferred from the rotor; a rotational shaft integrally formed with the roller; a vane that divides the compression chamber into suction and compression regions and transfers the rotational force to the roller; and oil feed passages provided in the rotational shaft and the roller to feed the lubricating oil to areas where two or more members are slidingly engaged with one another within the compression chamber.

  • Patent number: 9039390
    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.

  • Patent number: 8894388
    Abstract: A rotary compressor is provided that includes an electric motor that supplies electric power and a compression mechanism that compresses a refrigerant while first and second rotary members rotate upon receipt of the electric power from the electric motor. More particularly, the compressor has a compact design by forming a compression space within the compressor by a rotor of the electric motor that drives the compressor, maximizes compression efficiency by minimizing friction loss between rotating elements within the compressor, and has a structure that minimizes leakage of the refrigerant within the compression space.

  • Patent number: 8814546
    Abstract: A compressor is provided in which a rotary member is suspended on a stationary member and rotates to compress a refrigerant. In the stationary member, top and bottom ends of a stationary shaft are fixed to improve structural stability and assembly properties. Bearing covers are provided on a contact portion of the stationary member and the rotary member, such that the rotary member may rotate when suspended on the stationary member, which stabilizes operation. In the rotary member, a vane is integrally formed with a roller and mounted on a vane mounting hole of a cylinder-type rotor. Although, the rotary member is provided on an outer circumferential surface of the stationary member, suction and discharge operations of the refrigerant are performed in an axial direction, which lowers product height. Oil stored in a hermetic container is supplied to a lubrication passage provided between the stationary member and the rotary member.

Bearing covers are provided on a contact portion of the stationary member and the rotary member such that the rotary member can be rotated when suspended on the stationary member. This stabilizes the operation. In the rotary member, a vane is integrally formed with a roller and mounted on a vane mounting hole of a cylinder-type rotor. This reduces the vibration and prevents refrigerant leakage to improve the compression effect. Although the rotary member is provided on an outer circumferential surface of the stationary member, it is possible to perform the suction and discharge of the refrigerant in the axial direction. This can lower the product height.
