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: 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.

Abstract: A motor-operated compressor includes a casing having an inner space in which a driving motor, an orbiting scroll and a fixed scroll are accommodated, and a controller provided outside the casing. The casing includes an intake hole formed at a side adjacent to the controller and an exhaust hole formed at a side adjacent to the fixed scroll on the basis of the driving motor. The casing includes a communication passage formed between the casing and a stator of the driving motor, such that a refrigerant introduced into the inner space through the intake hole is introduced into the suction chamber through the driving motor. A back pressure space supporting the orbiting scroll is sealed by oil. The stator has teeth on its inner circumferential surface and protrusions on its outer circumferential surface, each protrusion being located within a width range of each tooth.
