、シート面１３の位置をずらす必要があった。Problem to be Solved by the Invention However, with the above configuration, when the discharge amount of the compressor increases, it is necessary to enlarge the discharge hole 11 to prevent overcompression, but if the discharge hole 11 is large, the vane 8 may be affected. Therefore, it could not be made very large, and in order to make it large, it was necessary to shift the position of the seat surface 13.
そこで本発明は、同一シート面位置で、吐出穴径を従来
より大きくでき、過圧縮の少ない回転圧縮機を提供でき
