ABSTRACT OF THE DISCLOSURE A refrigerant compressor has a casing encasing a compressor section and a driving section including an electric motor. A crank shaft is driven by the electric motor and an oil pipe is connected at one end to an open- ing of an attaching base fixed to the bearing of the crank shaft, the other end of the pipe being immersed in the lubricating oil collected in the case, and the opening being substantially concentric with the crank shaft, which has a journal portion, an eccentric portion and a main shaft portion. The journal portion is rotatably supported by the bearing, which cooperates with the attaching base in defining an oil pressure chamber.
