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

Abstract: A compressor includes: a fixed scroll; at least one discharge port; a reed valve; a valve stop; and a ventilation hole. The at least one discharge port is disposed in the fixed scroll. The reed valve is disposed in the fixed scroll so as to block the at least one discharge port. The valve stop is disposed in the fixed scroll, and restricts the lift amount of the reed valve. The ventilation hole is disposed in the valve stop. In the present aspect, the flow of refrigerant gas is smoothed to suppress the compression loss, and the force applied to the reed valve can be suppressed. As a result, the efficiency and reliability can be improved.

Abstract: A compressor including fixed scroll and revolving scroll configuring compression mechanism, compression chamber formed between fixed scroll and revolving scroll, intake chamber provided on an outer circumferential side of fixed scroll, discharge port provided in a central part of fixed scroll, muffler provided to cover discharge port at an upper part of fixed scroll, and heat-insulating member provided between fixed scroll and muffler space formed by muffler. After a refrigerant gas taken into intake chamber is compressed by revolving scroll revolving and compression chamber moving while changing a volume of compression chamber, the refrigerant gas is discharged from discharge port. The refrigerant gas discharged from discharge port is discharged into muffler space.
