Abstract: An oil pick-up device of a refrigeration compressor. This device includes an oil pick-up tube for raising a refrigeration oil to a drive part of the compressor. The oil pick-up tube has an annular protrusion for scattering the refrigeration oil ascending an outer surface of the tube and restricting generation of oil foams. The tube also has an air exhaust port for exhausting air bubbles and foreign substances of the refrigeration oil ascending the inside of the tube. This oil pick-up device efficiently scatters refrigeration oil while restricting the generation of oil foams, exhausts air bubbles as well as foreign substances from the refrigeration oil and prevents the generation of a pressure differential to reduce noise.
