Abstract: The present invention has an object to increase strength and stiffness of a compression mechanism and to prevent seizing thereof simultaneously. A scroll compressor 1 includes a compression mechanism 15 which compresses refrigerant. The compression mechanism 15 includes a fixed scroll 24 and a movable scroll 26. The fixed scroll 24 and the movable scroll 26 are formed of different materials. One of the two scrolls is a cast iron molding fabricated through semi-molten die casting, while the other is a grey iron casting. The grey iron casting has a tensile strength of greater than or equal to 250N/mm 2 and less than 300N/mm 2 .

Abstract: An object of the present invention is to reduce wear and deformation in a scroll member. A method for manufacturing an orbiting scroll as a scroll member comprises a step (a) and a step (b). In step (a), cast iron is formed and an iron casting is obtained. For example, the cast iron is formed by semi-molten die casting. In step (b), the iron casting obtained in step (a) is cut and an orbiting scroll is obtained. The iron casting (261) obtained in step (a) has a fixed part (261a) and a spiraling part (261b). In the fixed part (261a), the thickness (d2) of a portion (261a2) near the external periphery is greater than the thickness (d1) of a portion (261a1) near the center (9). The spiraling part (261b) is fixed to the fixed part (261a), and is made to extend in a spiraling formation around the center (9). By performing step (b) on the iron casting (261), a panel is obtained from the fixed part (261a), and a compression member is obtained from the spiraling part (261b).

Abstract: An object of the present invention is to provide a compressor that can be reduced in size, can be made commercially available at a low cost, and preserves the conventional slideability or machinability. The compressor (1, 101, 201, 301 401) comprises a first constituent element (23, 123, 125, 323, 325, 327, 327A, 327B) and a first slider (24, 124, 224, 324, 324A, 326, 326A, 424). The first constituent element is capable of being laser welded. The first slider is composed of cast iron capable of being laser welded and having a carbon content of from 2.0 wt% or more to 2.7 wt% or less. This first slider is joined to the first constituent element by laser welding without using a filler.

Abstract: An object of this invention is to reduce wear and deformation in a scroll member. A method for manufacturing an orbiting scroll includes a step (a) and a step (b). In step (a), cast iron is formed and an iron casting (261) is obtained. In step (b), the iron casting (261) obtained in step (a) is cut and an orbiting scroll is obtained. The iron casting (261) obtained in step (a) has a fixing part (261a) and a spiraling part (261b). The spiraling part (261b) is fixed to the fixing part (261a), and extends in a spiraling formation around a center (9). A dimension of a specified portion of the spiraling part (261b) is greater than the dimension of the same portion after step (b) is performed. Specifically, in a portion (2612) of an end (2611) at the center (9) of the spiral, a thickness (d1) is greater than a thickness (h1) of the portion (2612) after step (b) is performed.
