    Abstract: 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.

    Abstract translation: 提供一种压缩机，其具有蓄压器，该蓄压器在压缩机壳体的内部空间中形成蓄压室，从而减小压缩机的尺寸并简化组装过程。 具有制冷剂吸入通道的静止轴可直接连接到储液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，静止轴的两端可以由框架支撑以减少压缩机的振动而不使用单独的轴承。 包括蓄能器的压缩机的安装区域可以最小化，以提高采用压缩机的室外装置的设计灵活性并且使与其他部件的干扰最小化，由此便于室外装置的安装。
