PROBLEM TO BE SOLVED: To improve an oil cooling system of a horizontally oriented oil-lubricated compressor. SOLUTION: The oil lubricated compressor includes a bypass oil line connecting respective oil paths upstream and downstream of a motor. The bypass oil path permits oil to be detoured around the motor in a tube that is external to a compressor shell and flow back into a shell near a scroll inlet. The oil bypass line returns "excess" oil directly to a sump 28, rather than having it flow from a sump 27 to the sump 28 through an air-gap, thereby reducing both a drag on the motor and input power.
