Abstract

PURPOSE: To prevent a lubricating oil from flowing into a compression chamber which is at a stop by providing an oil feeding passage which connects the oil sump of a discharge chamber, etc., on the upper course to a compression chamber placed in the position of height equal to or lower than said oil sump on the lower course, and providing a part of said oil feeding passage in a position higher than the oil level of said oil sump.
CONSTITUTION: As a driving shaft 8 is rotated by means of a motor 7, a revolving scroll 10 is rotated causing a refrigerant gas to flow from a suction pipe 22 into a driving chamber 6 and, then, to be discharged into a discharge chamber 5 via the inside of a compression chamber 40 in between revolving and fixed scrolls 10, 13. In this case, the lubricating oil in a discharge-chamber oil sump 18 is fed into a first compression chamber 39 in the course of compressing tlarough a feed oil pipe 26 haviug a throttle passage and an injection port 30, with its pressure being gradually reduced. And, a part of the feed oil pipe 25 is placed in a position higher then the oil level of the discharge-chamber oil sump 18, thereby, preventing the lubricating oil in the discharge-chamber oil sump 18 from flowing into the first compression chamber 39 even when the oil level of the discharge-chamber oil sump 18 becomes higher than that of the first compression chamber 39.
