Abstract: A compressor includes fixed scroll (6) and revolving scroll (7) configuring compression mechanism (2), compression chamber (9), intake chamber (11), discharge port (12), muffler (16), and heat-insulating member (24) provided between fixed scroll (6) and muffler (16). After a refrigerant gas taken into intake chamber (11) is compressed by revolving scroll (7) revolving and compression chamber (9) moving while changing a volume of compression chamber (9), the refrigerant gas is discharged from discharge port (12). The refrigerant gas discharged from discharge port (12) is discharged into muffler space (14) formed by muffler (16). Heat-insulating member (24) includes heat-insulating member discharge port (25), lead valve (13), and recess (27).

Abstract: A sheet-shaped check valve 23 which opens and closes the injection passage 21 is placed in the check valve chamber 22, an injection discharge passage 21b portion connected to the compression chamber 13 of the injection passage 21 and the check valve chamber 22 open from an outer surface of the fixed scroll 11, a lid body 25 is attached to openings of the injection discharge passage 21b and the check valve chamber 22 such that the check valve 23 is sandwiched between the openings and the lid body 25, and the injection discharge passage 21b and the check valve chamber 22 are hermetically closed, thereby forming the injection passage 21. According to this, it is possible to provide a reliable, efficient and inexpensive compressor with an injection mechanism.
