Abstract
A scroll compressor is provided which is configured such that an arcuate section may be formed from a suction end of a wrap to a first point to increase a suction volume, and a logarithmic spiral section in which a wrap thickness increases may be formed from a second point to a discharge end of the wrap. This may increase a volume ratio of the compressor so as to increase a capacity of the compressor and prevent damage to the wrap due to a high compression ratio operation, thereby enhancing reliability of the compressor.
