Turbine housing for an exhaust gas turbocharger

A turbine housing for an exhaust turbocharger, the turbine housing being configured for receiving a turbine wheel that is rotatable about an axis, the turbine housing comprising:

• an exhaust gas inlet;
• an axial exhaust gas outlet pointing in an outlet direction;
• and
• a single-flow, spiral exhaust gas routing having a volute and a volute outlet gap being configured so that exhaust gas flows from the volute to the turbine wheel, wherein the exhaust gas routing is fluidically connected to the exhaust gas inlet and is defined by an internal wall of the turbine housing;
• wherein the volute has a portion which encircles the axis and has a convexity of the internal wall, in that the convexity, counter to the outlet direction, extends beyond the volute outlet gap, and in that sectional faces, through which the axis runs, each have a volute contour with a straight linear portion and wherein the straight linear portion conjointly with the axis defines an angle facing the exhaust gas outlet that is less than or equal to 90°.
