TURBINE FOR AN EXHAUST TURBOCHARGER HAVING A TWO-VOLUTE TURBINE HOUSING AND A LINEAR VALVE FOR VOLUTE CONNECTION AND WASTEGATE CONTROL

摘要

A turbine for an exhaust-gas turbocharger has a turbine housing formed with two volutes through which an exhaust gas can flow and which are separated by a separating wall. Only a single wastegate valve is provided for both volutes. The wastegate valve is a linear valve with a linear valve element. The linear valve element is received in the separating wall and is movably guided in its axial direction in the separating wall.
