Turbine for an exhaust gas turbocharger with a two-volute turbine housing and a valve arrangement having improved outflow

A turbine for an exhaust-gas turbocharger, the turbine comprising:

• a turbine housing having two exhaust-gas volutes for a flow of exhaust gas, a separating wall between said two exhaust-gas volutes, and a common wastegate opening;
• a linear valve having a valve element for selectively opening and closing said common wastegate opening, and a displacement shaft, with a shaft longitudinal axis, for actuating said valve element;
• said displacement shaft extending through said separating wall in a direction of a separating wall plane spanned by said separating wall and movably disposed in a direction of said shaft longitudinal axis in said separating wall;
• and
• said valve element being disposed in a separating wall cutout between said exhaust-gas volutes and being led out from a region of said exhaust-gas volutes, in a direction of the wastegate opening, toward a valve seat which is formed on an inner side of said wastegate opening facing towards said exhaust-gas volutes.
