Abstract
In a refrigerating machine, a reservoir heated by an electric motor driving a compressor contains oil up to certain level. The reservoir is fed with refrigerating liquid complemented with oil. The liquid vaporizes while oil falls down in the liquid state. A number of lubrification conduits connect individual bearings of the compressor with the reservoir above the oil level on the one hand and with the reservoir below the oil level through a micro-orifice on the other hand, so as to send to the bearings refrigerating gas loaded with an oil mist. The bearings are in fluid communication with the intake of the compressor.
