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.
