<P>PROBLEM TO BE SOLVED: To prevent degradation in performance due to overcompression of a refrigerant inside a compression chamber regardless of the level of a discharge pressure of a compressor or the level of a pressure of an injection refrigerant. <P>SOLUTION: A scroll compressor includes an injection port 1f for injecting the injection refrigerant which is provided more on the outer peripheral side of a spiral tooth 1b than a discharge port 1d provided on the center part of the spiral tooth 1b, and also includes a relief port 1e for discharging the refrigerant at or higher than a discharge pressure which is provided more on the outer peripheral side of the spiral tooth 1b than the discharge port 1d and more on the center side of the spiral tooth 1b than the injection port 1f. <P>COPYRIGHT: (C)2012,JPO&INPIT |
