Abstract: PROBLEM TO BE SOLVED: To provide a rotary compressor for reducing an input loss, by reducing a sliding loss in an upper bearing, by improving slidability of a rotating shaft and an inner peripheral sliding surface of the upper bearing. SOLUTION: An oil groove 15 arranged on the inner peripheral sliding surface of the upper bearing 6 has a first oil groove 15A and a second oil groove 15B divided in the axial direction of a shaft 4 by the cylinder 5 side and the compression driving part (electric motor part 102) side. Since the first oil groove 15A and the second oil groove 15B can improve the slidability of the rotating shaft 4 and the inner peripheral sliding surface of the upper bearing 6 by minimizing reduction in load capacity by the oil groove of the upper bearing 6 by arranging an angle difference of about 180° in the circumferential direction of the inner peripheral sliding surface of the upper bearing 6, the sliding loss in the upper bearing can be reduced.

Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of a compressor without increasing material cost from present cost by reducing leak loss while restraining friction resistance of a sliding surface of a roller end surface.
SOLUTION: A shallow spiral groove is provided on a roller inner surface part in a direction in which oil flows upward to rotation of a crankshaft. Leak quantity from the roller both end surfaces can be greatly reduced by a configuration in which section area of the spiral groove reduces toward the oil flow direction. Efficiency can be improved as compared to former compressors. Since sliding loss at the roller end surface is simultaneously reduced, reliability can be improved by inhibiting occurrence of wear, seizure and the like.

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.
