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.

Compressor with injection mechanism

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.

Compressor

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.

According to a compressor of the present invention, the compressor further comprises an oil separating mechanismwhich separates oil from the refrigerant gas discharged from the compressing mechanism, the oil separating mechanismincludes a cylindrical spacein which the refrigerant gas orbits, an inflow portionfor flowing the refrigerant gas discharged from the compressing mechanisminto the cylindrical space, a sending-out portfor sending out, from the cylindrical spaceto the one container space, the refrigerant gas from which the oil is separated, and an exhaust portfor discharging the separated oil and a portion of the refrigerant gas from the cylindrical space, and a center of the sending-out portis deviated in a direction opposite from the inflow portionfrom a center axis of the cylindrical space
