Turbine for an exhaust turbocharger having a two-channel turbine housing and a valve for channel connection

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

• a turbine housing having two exhaust-gas volutes for an exhaust gas flow, a separating wall between said two exhaust-gas volutes, a common wastegate opening, and a flap disk of a wastegate valve for selectively closing and opening said wastegate opening;
• a valve element configured for controlling a volute connection between said two exhaust-gas volutes, said valve element having a displacement shaft and a closing body connected to said displacement shaft;
• said displacement shaft extending through a bore formed in a separating wall plane of said separating wall between said two volutes;
• and
• said closing body being arranged in the volute connection of said separating wall in order to selectively open and close the volute connection, and said volute connection being formed as a passage recess, which is formed in said separating wall in a region of said wastegate opening and runs transversely with respect to said separating wall plane.
