摘要： An object is to provide a scroll compressor capable of preventing degradation in performance and the occurrence of abnormal noise due to a torsional moment applied to an orbiting scroll, by utilizing the structural advantages of so-called stepped scroll compressors. In a so-called stepped scroll compressor (1), in a pair of compression chambers (16) arranged in a point-symmetrical configuration among a plurality of compression chambers (16), the volume V1 of the compression chamber (16) formed on the ventral-surface side of the fixed spiral wrap (14B) of the fixed scroll (14) when intake is cut off and the volume V2 of the compression chamber (16) formed on the ventral-surface side of the orbiting spiral wrap (15B) of the orbiting scroll (15) are different from each other.
