Abstract:

An oil level control device for a compressor wherein lubricant (L) is stored in a storing portion (2c) of a casing (2), wherein a lubricant take-out pipe (15) is caused to communicate with the storing portion (2c) at one end and with a suction chamber (14) of a scroll mechanism (3) at the other end thereof, and wherein an inlet end of the lubricant take-out pipe (15) is opened at an oil level upper limit position of the storing portion (2c) in the vicinity of a lower end of a rotor (9b), whereby when the oil level of the lubricant (L) is raised to the oil level upper limit position, an excessive portion of the lubricant (L) is led from the storing portion (2c) to the scroll mechanism (3) through the lubricant take-out pipe (15) by virtue of the difference in pressure between a lower space (2b) of the casing (2) and the suction chamber (14) to thereby lower the oil level.
