Abstract: PROBLEM TO BE SOLVED: To solve the problem that a fixed scroll is locally brought into contact with a slewing scroll by the pressure deformation of the slewing scroll to thereby deteriorate capability, increase input, and further cause seizure.
SOLUTION: A clearance is formed between the lap tip 13c of the slewing scroll 13 and the lap groove bottom surface 12d of the fixed scroll 12. The end plate 13a of the slewing scroll 13 is formed to have different thickness in a peripheral part 13o, an intermediate part 13m, and a boss inner peripheral part 13i. A seal member 78 is arranged on a slewing scroll back surface 13e corresponding to the intermediate part 13i. A rotation restraint mechanism 14 is arranged on the slewing scroll back surface 13e corresponding to the peripheral part 13o. Thereby, pressure deformation is suppressed.

Abstract: PROBLEM TO BE SOLVED: To increase the reliability of a fixed scroll and a rotary scroll of a scroll compressor to match the compressor to recent refrigerating air conditioners increased in efficiency and life and using a high-pressure refrigerant such as carbon dioxide.
SOLUTION: The thickness H of an end plate of the rotary scroll 13 on the inside of a bearing housing part 13c is 10-35% of the inner diameter D of the bearing housing part 13c. When the scroll compressor is under high load, the tooth bottom of the end plate 13a of the rotary scroll 13 corresponding to the bearing housing part 13c and the winding start part at the lap end 12b of the fixed scroll 12 are deformed, and also the winding start part of the fixed scroll 12 is heated, and thermally expanded to the rotary scroll 13 side. However, since the tooth bottom of the end plate 13a of the rotary scroll 13 on the inside of the bearing housing 13c is flexibly deformed to the end 12b of the fixed scroll 12 by pressure, nonuniform contact does not occur, and the high reliability of the scroll compressor can be realized.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor improved in reliability by preventing a fixed scroll and a rotary scroll from being seized.
SOLUTION: The inclusion of oil between the fixed scroll 2 and the rotary scroll 3 is promoted by reducing the height of a lap from the centerline of the lap toward the side surface of the lap in the thickness direction of the lap even when the axal gap between the fixed scroll and the rotary scroll is reduced. A zone where the height of the lap is constant in the thickness direction of the lap of a swirl lap is formed. Since the leakage of a refrigerant is reduced, high lubricating performance is maintained irrespective of the operating conditions. Consequently, the high performance scroll compressor can be provided.

Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein since a temperature gradient is generated in the thickness direction of a lap of a fixed scroll, thermal expansion differs between inner and outer peripheral sides of the lap, leading to uneven contact of a lap tip part.
SOLUTION: Considering the temperature gradient generated in the thickness direction of the lap 12b of the fixed scroll 12, a lap upper face 12c of the fixed scroll 12 is partially lowered with respect to a portion 12f contacted with a panel board 13a of a turning scroll 13 on the outer peripheral face of the fixed scroll 12. This structure can absorb dimensional change of the lap 12b caused by thermal expansion.

Abstract: PROBLEM TO BE SOLVED: To solve a problem in which a gap can be eliminated at an outside contact point A1 after thermal expansion but a gap is formed at a center part contact point A2 to cause leak of compressed refrigerant and performance drop by mere phase shift in prior art, and in which performance drop gets larger when especially materials of a fixed scroll and an orbiting scroll are different and difference of thermal expansion coefficients is large.
SOLUTION: Phase angle of scroll laps is shifted in a direction in which an outside of the orbiting scroll lap 2 and an inside of the fixed scroll lap 1 separate from a condition where phase of mutual scroll laps is shifted by 180°, and lap thickness is made thicker by off-setting a lap outside at a winding start section of the orbiting scroll lap 2 during assembly. Consequently, a gap at a contact point of the outside of the orbiting scroll lap and the inside of the fixed scroll lap near a center part can be made small during hot operation.
