Abstract

In an exhaust gas turbocharger turbine for an internal combustion engine having a housing including a turbine wheel rotatably supported in the housing, wherein the housing has an exhaust gas flow guide section including an exhaust gas flow control arrangement with a guide vane structure for directing exhaust gas onto the turbine rotor, an adjustment mechanism with an axially movable control slide is provided which is movable by an operating fork which is slidably supported on a guide element and engages the control slide at opposite sides so as to prevent cogging of the movable control slide during movement into, and out of, the exhaust gas flow guide section.
