    Abstract: A hermetic compressor according to the present disclosure may include an oil guide disposed on a rotating shaft between a driving motor and a main frame, the oil guide may include an oil block surrounding a main bearing surface between the main frame and the rotating shaft, and one end of the oil block may radially overlap a shaft support protrusion of the main frame. This can suppress oil returned after lubricating a compression unit from being scattered, thereby reducing a leakage of the oil to outside of a casing through a refrigerant discharge pipe.

    Abstract: A compressor includes a case, a driving motor including a stator mounted inside the case and a rotor disposed radially inward of the stator and rotatable, a centrifugation space defined inside the case by one side of the driving motor and the case, a discharge pipe passing through the case and defining a refrigerant inlet hole, a rotation shaft coupled to the rotor to rotate, a compressing portion defined at the other side of the driving motor, where refrigerant is compressed by rotation of the rotation shaft, and a rotating member disposed to spread a rotary power of the rotor to the centrifugation space, thereby providing a centrifugal force to refrigerant and oil. The rotating member is disposed at one side of the rotor to rotate integrally with the rotor.

    Abstract: A compressor is disclosed. The compressor includes a case having an oil reservoir space for storing oil in a lower portion of the case and a refrigerant discharge pipe for discharging a compressed refrigerant in an upper portion of the case, a drive motor provided in the case, a rotary shaft rotatably coupled to the drive motor, a compression unit coupled to the rotary shaft to compress the refrigerant, and a discharge cover hermetically coupled to a lower end of the compression unit and configured to guide an oil-containing refrigerant compressed by the compression unit toward the refrigerant discharge pipe, wherein a guide is provided between the compression unit and the discharge cover and configured to guide an oil-containing refrigerant discharged from the compression unit toward the refrigerant discharge pipe.

    Abstract: An electric compressor includes a first scroll and a second scroll engaged with the first scroll and making an orbiting motion to form a pair of two compression chambers with the first scroll. A rotary shaft is eccentrically coupled to the second scroll and is rotatably supported by a bearing member. A frame is fixed to an opposite side of the first scroll from the second scroll with the second scroll being interposed between the frame and the first scroll. The frame includes a bearing support portion, and the bearing member is inserted into and fixed to the bearing support member with an interference fit.
