Abstract: The present invention discloses a scroll compressor comprising: a first cover fixed on a fixed scroll; and a second cover fixed on the first cover. The first cover includes a first top plate and a first peripheral wall, which forms a first space inside. The second cover includes a second top plate and a second peripheral wall, which forms a second space inside. The first space connects to a discharge port that penetrates the fixed scroll. Multiple through holes are formed to penetrate the first top plate so that the through holes with different diameters connect the first space and the second space.

Abstract: A refrigerating cycle apparatus is equipped with a plurality of outdoor units, each of which includes at least one high-pressure type compressor with refrigerant and lubricating oil stored therein. A discharge pipe of the respective compressor is connected to a main discharge pipe for jointly discharging refrigerant and oil to the indoor unit. A suction pipe of the respective compressors is connected for returning the refrigerant and the oil from the indoor unit to the compressor. Each outdoor unit comprises a first oil balancing circuit connected between a side surface of the casing of the respective compressor and the main discharge pipe for allowing a flowing-in of the exceeding oil from the casing of the compressor. In another embodiment, each outdoor unit may include a second oil balancing circuit connected between a side surface of the casing of the respective compressor and the main suction pipe.

Abstract: An aluminum wire, which is an electric wire of an electric motor of a compressor, is wound around a copper wire, which is another electric wire, at interval in the length direction. The portion around which the aluminum wire is wound is brazed with a brazing material containing a flux. Thus, the aluminum wire and the copper wire are joined together, and an electric wire joint section is formed. Insulating paper is mounted to the electric wire joint section. The inner surface of the insulating paper is brought into contact with the surface of the electric wire joint section to which a residue of the flux adheres.
