A pair of scroll members 10, 12 in a compressor have outer end- sealing surfaces 18, 36 and raised inner end-sealing surfaces 20, 38, the spiral ribs, or "wraps", 14, 32 having corresponding outer and inner tip-sealing surfaces 24, 42 and 26, 44. The compression ratio is thereby increased without lengthening the wraps. Vertical transition surfaces 22, 28, 40, 46 may be circular cylindrical or conic. <IMAGE> |
