Abstract

The object of the present invention is to provide a scroll compressor, which increases a volume ratio with an outer diameter of spiral bodies remains the same, and has a high efficiency at the time of high pressure ratio operation. The solution of the present invention is that in a turning scroll and fixed scroll having the spiral body constituting a basic volute curve as an algebraic spiral curve, respectively, an inner side wall face of the fixed scroll spiral body is extended to a position exceeding an outer side wall face of the turning scroll spiral body, and the center of the basic volute curve and the center of an end plate are offset. A fluid injection inlet is arranged in a position continuing long to a closed space having a small design volume ratio.
