Abstract

PURPOSE: To prevent the occurrence of seizure due to deficiency in oil and deterioration in refrigerating capacity due to discharge of oil, by a method wherein the opening of an oil return pipe is formed in a position allowing a negative pressure in the vicinity of the inlet of an oil feed hole to be exerted.
CONSTITUTION: An oil separator 14 is located around a discharge pipe 13 in an enclosed vessel 1, an oil return pipe 17 is suspended from the bottom of the oil separator 14, and is open in lubricating oil of an oil reservoir 10. An opening 19 of the oil return pipe 17 is located in the vicinity of an inlet 22 of a feed oil hole 21 formed in a rotary shaft 20, and the lubricating oil, separated from the oil return pipe 17, can be recovered by means of incoming of the lubricating oil.
