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.

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.

Abstract: In accordance with a fuel cell module, a cell stack is housed in a housing including a box and a lid, and the lid is provided with a first gas flow channel through which either one of oxygen containing gas and exhaust gas flows. Therefore, the configuration of the housing can be simplified. Since the lid is provided with the gas flow channel, an accommodation space inside the box can be enlarged, the cell stack can be easily housed inside the housing through an opening, and the fuel cell module can be easily assembled.

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).
