    • A scroll casing forms a scroll flow passage of a centrifugal compressor, and, provided that, in a cross section of the scroll flow passage, Eo is an outer end of the scroll flow passage in a radial direction of the centrifugal compressor, Ef is a front end of the scroll flow passage in an axial direction of the centrifugal compressor, and Mw is a middle point of a maximum flow-passage width Wmax of the scroll flow passage in the radial direction, a flow passage height H of the scroll flow passage in the axial direction gradually increases from a position of the outer end Eo to a position of the front end Ef with respect to the radial direction, and the scroll flow passage has a recirculation flow suppressing cross section in which the front end Ef is disposed on an inner side, in the radial direction, of the middle point Mw, in a section disposed at least partially in a region closer to a scroll start than a connection position of the scroll start and a scroll end.
    • 涡旋壳体构成离心压缩机的涡旋流路,在涡旋流路的截面中,Eo是涡旋流路的离心压缩机的径向外端,Ef是 涡旋流路的前端部在涡旋流路的轴向上具有涡旋流路,并且Mw是涡旋流路的径向最大流路宽度Wmax,涡旋流路的流路高度H 在轴向上从外端Eo的位置到前端Ef相对于径向的位置逐渐增大,并且涡旋流动通道具有其中前端Ef设置在其上的再循环流动抑制横截面 在中点Mw的径向内侧至少部分地设置在比滚动开始点和滚动结束点的连接位置更靠近滚动开始的区域。
