Abstract

PURPOSE: To improve the lubrication of a bearing shaft and a rotor, reduce the mechanical loss, and prevent seizure by providing a refrigerant discharge pipe communicated to the outside and having a discharge port in the same direction as the rotation of a rotor, an upper bearing, and a lower bearing on a housing.
CONSTITUTION: A refrigerant discharge pipe 20 communicated to the outside and having a discharge port 10 in the same direction as the rotation of a rotor 8, an upper bearing 12, and a lower bearing 14. Then, the lubricating oil in the discharged refrigerant and the lubricating oil discharged from an oil groove 11 is scattered to the inner wall of a housing 18 by the centrifugal force and drops along the wall face and is accumulated at the lower section. Since the discharge port 19 of the refrigerant discharge pipe 20 is provided in the same direction as the rotation, the quantity of the lubricating oil carried into the refrigerant cycle directly from the refrigerant discharge pipe 20 is small. Therefore, the oil quantity required for lubrication is invariably secured in a compressor, the lubrication of bearings 12, 14, a shaft 1, and a rotor is not impaired, the mechanical loss is reduced, and seizure can be prevented.
