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.
