ABSTRACT:
In a flow control apparatus of an exhaust gas turbocharger turbine for an internal combustion engine including a rotor disposed in a turbine casing having a spiral guide channel arranged around the rotor with a mouth area defining an inlet opening for directing the exhaust gas to the turbine rotor, a control sleeve including a flow guide section with flow guide passage is axially movably supported between the spiral guide channel and the rotor. The flow guide passages have guide characteristics which vary depending on the axial location on the sleeve so that the characteristics of the exhaust gas flow admitted to the rotor can be changed by axial movement of the control sleeve. Adjacent the flow guide passages the control sleeve has an integral annular end section for blocking the exhaust gas flow so as to form a flow-throttling cross-section at the mouth area for engine brake operation.
