SCROLL COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a lubrication structure capable of maintaining a sufficient lubrication in a pin/aperture type own rotation preventing mechanism A using a flange part 12a of rotation scroll 12. SOLUTION: An own rotation preventing mechanism A is provided between a flange part 12a formed by radially enlarging and extending a diameter of an end plate part 12c of rotation scroll 12 and an enlarged diameter part of an end plate part 11b of stationary scroll 11 formed in opposed to the flange part 12. A groove G communicating an own rotation preventing aperture 12a a constituting this own rotation preventing mechanism A with a coolant passage part for flowing a coolant at the inside of a compressor 1 is formed. Thereby, a portion of gas cooling medium including a lubricating oil is fed to the own rotation preventing mechanism A through the groove G and a lubrication of a turn-stop pin 13 and the own rotation preventing aperture 12 is sufficiently maintained.
