<P>PROBLEM TO BE SOLVED: To obtain a scroll compressor configured to improve reliability. <P>SOLUTION: The scroll compressor includes a compression mechanism 14, a frame 4, a discharge tube 12, a discharge check valve 20, and a spring. The frame 4 is provided with: a valve passage 4f for slidably housing the discharge check valve 20; a discharge communication path for making the inside of a sealed container 10 communicate with the discharge tube 12; a valve stop face 4g for holding the spring, and stopping the discharge check valve 20 pressed by discharge pressure which is produced when refrigerant gas compressed by the compression mechanism 14 is discharged to the outside of the sealed container 10, by exceeding biasing force of the spring; and a refrigerant introduction path 4e for introducing refrigerant gas flowing back to the discharge communication path from the outside of the sealed container 10 while the discharge check valve 20 is sliding on the valve stop face 4g. <P>COPYRIGHT: (C)2013,JPO&INPIT |
