In a rotary compressor for refrigerants of the type having, within a sealed case, a refrigerant compressing device and a motor disposed thereabove for driving the same and having a vertical rotor shaft, an oil-separating member of umbrella shape with a downwardly-directed peripheral rim is disposed coaxially above and fixed relative to the top end of the rotor and functions to guide compressed refrigerant containing lubricating oil particles toward and through the motor windings of the motor thereby to separate the oil particles from the refrigerant, which is then delivered under pressure.
