Abstract: PROBLEM TO BE SOLVED: To solve a problem that an asymmetrical scroll compressor in which a compression chamber formed on an outer wall side of a turning scroll has a suction volume larger than a compression chamber formed on an inner wall side may suffer the deterioration in compression efficiency ascribable to leakage of working fluid of a scroll wrap wall surface due to insufficient sealing oil supply to a compression chamber inside the turning scroll when a compression chamber side opening end of a route for connecting a back pressure chamber with the compression chamber is provided only in a compression chamber formed outside the turning scroll.
SOLUTION: A route 55 is provided which connects a back pressure chamber 29 with a compression chamber not connected to a suction port 17. A compression chamber side opening end 55-2b of the route 55 is intermittently opened to an inner compression chamber 15b and an outer compression chamber 15a in a turning scroll 11. A total oil supply amount to the inner compression chamber 15b is made larger than a total oil supply amount to the outer compression chamber 15a.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor having both high reliability and high efficiency.
SOLUTION: The surface hardness of the upper surface 9d of the lap of a rotary scroll is made smaller than that of the other surfaces than at least the upper surface 9d of the lap of the rotary scroll. Since the sliding surface of the rotary scroll is fitted earlier and the deterioration of input can be avoided even if the upper surface 9d of the lap of the rotary scroll is brought into slidable contact therewith under high temperature, high compression ratio operating conditions. Consequently, the scroll compressor having high reliability and high efficiency can be provided.

Abstract: PROBLEM TO BE SOLVED: To prevent thermal decomposition of a refrigerant that does not contain chlorine atom, has a low global warming potential, and mainly includes hydrofluoroolefin having double bond between carbon and carbon, and to provide a rotary compressor that has high reliability and high efficiency.SOLUTION: In the compressor, a single refrigerant consisting of a refrigerant whose base component is hydrofluoroolefin having double bond between carbon and carbon or a mixed refrigerant containing the refrigerant is used as an operation refrigerant. The compressor includes: a crankshaft 31 connecting an electric motor 2 with a compressor mechanism 3; and a bearing 34 pivotally supporting the crankshaft 31. A boss diameter of the bearing is formed such that a tip side is thinner than a base side. As a result, a thinner portion of the bearing elastically deforms to go away. Accordingly, prevention of increase in temperature near a sliding part causes: reduction of reliability due to operation refrigerant decomposition to be avoided; and the compressor to have high efficiency by reducing sliding loss.
