Outflow region of a compressor, compressor having an outflow region of said type, and turbocharger having the compressor

A compressor having a compressor wheel and an outflow region, the outflow region having a flow channel which is delimited by a shroud-side side wall and a hub-side side wall, wherein, in a region of the compressor wheel outlet, the flow channel extends from a compressor wheel outlet edge to a diffuser vane inlet edge of a diffuser region, wherein the diffuser region is in fluid communication with the region of the compressor wheel outlet and has a multiplicity of diffuser vanes;

• and
• wherein the hub-side side wall has a S-shaped contour that includes a convex segment adjacent the compressor wheel outlet edge and a concave segment adjoining an outlet end, in a flow direction of flow from the compressor wheel outlet, of the convex segment;
• and
• wherein the shroud-side side wall includes a contour that is convex from the compressor wheel outlet edge to the multiplicity of diffuser vanes;
• and
• wherein the contours of the hub-side side wall and the shroud-side side wall are configured in such a way that, in the flow direction, the cross-sectional area of the flow channel decreases to a minimum and increases from the minimum.

A turbocharger having a compressor and a turbine, the compressor having a compressor wheel and an outflow region, the outflow region having a flow channel which is delimited by a shroud-side side wall and a hub-side side wall, wherein, in a region of the compressor wheel outlet, the flow channel extends from a compressor wheel outlet edge to a diffuser vane inlet edge of a diffuser region, wherein the diffuser region is in fluid communication with the region of the compressor wheel outlet and has a multiplicity of diffuser vanes;

• and
• wherein the hub-side side wall has a S-shaped contour that includes a convex segment adjacent the compressor wheel outlet edge and a concave segment adjoining an outlet end, in a flow direction of flow from the compressor wheel outlet, of the convex segment;
• and
• wherein the shroud-side side wall includes a contour that is convex from the compressor wheel outlet edge to the multiplicity of diffuser vanes;
• and
• wherein the contours of the hub-side side wall and the shroud-side side wall are configured in such a way that, in the flow direction, the cross-sectional area of the flow channel decreases to a minimum and increases from the minimum.
