ことが多い。2. Description of the Related Art Various types of compressors are used in a refrigeration cycle. These compressors include a head having a discharge chamber for discharging the refrigerant and a suction chamber for sucking the refrigerant. The head has a structure in which a discharge chamber and a suction chamber are separated from each other by a partition wall, and is usually manufactured as an integrally cast product by aluminum die casting in order to reduce the weight.

小型化できる。Recently, CO2 has been used as a refrigeration cycle.
The use of a refrigeration cycle using 2 as a refrigerant has been proposed.
This type of refrigeration cycle is usually called a supercritical refrigeration cycle. Since this supercritical refrigeration cycle can be expected to have high refrigeration capacity, it is possible to reduce the size of the compressor. For example, when a piston-type compressor is used, the diameter of the cylinder bore is reduced to, for example, about ２, so that the compressor can be downsized.

隔壁を厚く作ることができなくなる。In the supercritical refrigeration cycle, the refrigerant compressed by the compressor has a higher temperature (about +5) than the conventional refrigeration cycle using chlorofluorocarbon as a refrigerant.
(0 ° C.) and high pressure (about +10 Mpa), it is necessary to increase the strength of the partition wall between the discharge chamber and the suction chamber. However, it is difficult to increase the strength of a downsized compressor depending on the thickness of the partition wall. For example, in a piston type compressor, the partition wall between the discharge chamber and the suction chamber is provided at a position that bisects the opening of the cylinder bore, so when the diameter of the cylinder bore decreases, the relationship between the suction port and the discharge port increases.
The partition cannot be made thick.

Rotates. Since the rotation of the swing plate 41 is locked by the guide 43, the swing plate 41 swings according to the inclination of the swash plate without rotating. As a result, the piston 17 reciprocates in the cylinder bore 11 via the piston rod 42. Piston 1

As a result, the discharge chamber 14 has a high pressure. However, since the inner partition wall 45 forming the discharge chamber 14 is formed of a high-strength material, it can have high strength. Therefore, the reciprocating compressor can be used even when the compressed refrigerant has a high temperature and a high pressure as in a supercritical refrigeration cycle using CO 2 as a refrigerant. In addition, since the first wall portion 46 can be made thin, it is easy to reduce the diameter of the cylinder bore 11 and downsize the compressor. As a result, the weight of the compressor can be reduced.
