A compressor having an oil pick-up tube which filters incoming lubricant, and increases the volumetric pumping capacity of the compressor. The oil pick-up tube is attached to the crankshaft of the compressor, and is partially disposed within an oil sump also provided in the compressor. When the motor of the compressor is energized, the crankshaft and the oil pick-up tube rotate, and oil from the oil sump is drawn into the oil pick-up tube. A passageway is provided within the motor shaft to communicate oil from the oil pick-up tube to the compressor mechanism of the compressor for lubrication purposes. A cylindrical screen is also provided within the oil pick-up tube to both filter the incoming oil and provide a surface to which the oil adheres as it migrates upward through the rotating tube and expels the oil radially outward to increase the velocity of the migrating oil. The volumetric pumping capacity of the compressor is thereby increased. A pitot tube is provided at the top of the axial oil passageway to create an additional vacuum within the axial oil passageway and thus increase the volumetric pumping capacity of the compressor.
