    • A scroll compressor having a rotational shaft insertion hole and a fabrication method thereof are provided. The scroll compressor includes a casing; a fixed scroll fixed to an inner wall surface of the casing; an orbiting scroll combined with the fixed scroll to form a compression chamber while performing an orbiting movement with respect to the fixed scroll; a rotational shaft having a shaft portion inserted into the fixed scroll, an eccentric portion that penetrates the fixed scroll to be combined with the orbiting scroll, and a neck portion having a diameter less than a diameter of the eccentric portion to connect the eccentric portion to the shaft portion, wherein the shaft portion, the eccentric portion, and the neck portion are integrally formed; a fixed bush interposed between the fixed scroll and the shaft portion; and a driving unit configured to drive the rotational shaft. A neck portion insertion hole, into which the neck portion is inserted, and a shaft portion insertion hole, into which the shaft portion is movably inserted in a transverse direction, are formed at the fixed scroll, and the fixed bush restricts a transverse directional movement of the shaft portion to maintain a state in which an outer circumferential portion of the neck portion insertion hole is inserted into the neck portion.

    • A compressor is provided having an accumulator that forms an accumulating chamber in an internal space of a shell of the compressor, reducing a size of the compressor and simplifying an assembly process. A stationary shaft having a refrigerant suction passage may be directly connected to the accumulator to prevent leakage of refrigerant. Further, a center of gravity of the accumulator may correspond to a center of gravity of the compressor to reduce vibration noise of the compressor caused by the accumulator. Furthermore, both ends of the stationary shaft may be supported by a frame to reduce compressor vibration without using a separate bearing. An installation area of the compressor including the accumulator may be minimized to enhance design flexibility of an outdoor device employing the compressor and minimize interference with other components, thereby facilitating installation of the outdoor device.
    • 提供了一种压缩机,其具有在压缩机壳体的内部空间中形成蓄积室的蓄能器,减小了压缩机的尺寸并简化了组装过程。 具有制冷剂吸入通道的固定轴可以直接连接到蓄能器以防止制冷剂泄漏。 此外,蓄能器的重心可以对应于压缩机的重心,以减少由蓄能器引起的压缩机的振动噪声。 此外,固定轴的两端可以由框架支撑,以减少压缩机振动,而不使用单独的轴承。 可以将包括蓄能器的压缩机的安装区域最小化,以提高使用压缩机的室外装置的设计灵活性,并最小化与其他部件的干扰,从而便于室外装置的安装。

    • A compressor eliminates sliding contacts between a cylinder (132) and a roller (142) to minimize the mixing of lubricating oil into refrigerant, and is structured to evenly distributing lubricating oil over sliding contact portions of a compressor actuator by pumping the oil from the inside on an axis of rotation (141), the compressor comprising: a hermetic container (110) storing oil at a lower portion; a stator (120) mounted within the hermetic container (110); a cylinder type rotor (130) rotating within the stator (120) by a rotating electromagnetic field from the stator (120), with the rotor (130) defining a compression chamber inside; a roller (142) rotating within the compression chamber of the cylinder type rotor (130) by a rotational force transferred from the rotor (130), with the roller (142) compressing refrigerant during rotation; an axis of rotation (141) integrally formed with the roller (142) and extending in an axial direction; a vane (143) dividing the compression chamber into a suction region where refrigerant is sucked in and a compression region where the refrigerant is compressed/discharged from, with the vane (143) transferring the rotational force from the cylinder type rotor to the roller (142); and oil feed passages provided to the axis of rotation (141) and the roller (142), with the oil feed passage feeding oil that is pumped along the motion of the axis of rotation (141) to an area where two or more members are slid onto within the compression chamber.
