摘要： In a scroll compressor, a center (Vc) of a turning scroll body (24) is shifted with respect to a drive central axis (D) so that a distance (L) between a gravity center (G) and the drive central axis (D) in a turning scroll (20) becomes smaller than a predetermined allowable value set based on theoretical displacement and mass of the turning scroll (20). A moment force about the drive central axis (D) acting on the turning scroll (20) is reduced during revolving, and an alternating force acting on an autorotation preventing pin in the turning scroll (20) is reduced to an allowable level.

摘要： A scroll compressor is provided that can reliably prevent a situation in which a product whose performance is degraded due to misassembly of a tip seal is shipped. In the scroll compressor, tip seals (17A, 17B, 18A, 18B) of different lengths are embedded in tip surfaces of a fixed spiral wrap of a fixed scroll and an orbiting spiral wrap of an orbiting scroll. Among the tip seals (17A, 17B, 18A, 18B), thicknesses (T2, T3) of the shorter tip seals (17A, 18B) are made thicker than thicknesses (T1, T4) of the longer tip seals (17B, 18A), and depths (D1 through D4) of seal grooves (14F, 14G, 15F, 15G) in which the tip seals (17A, 17B, 18A, 18B) are embedded, respectively, are formed to different depths in correspondence with the thicknesses (T1 through T4) of the respective tip seals.
