ABSTRACT:
In an exhaust gas turbocharger turbine for an internal combustion engine with a turbine housing having an annular flow path, a control sleeve axially movably supported in an annular space formed in the turbine housing adjacent the annular flow path and having at its front end a flow guide structure with vanes for guiding the exhaust gas flow when the flow guide structure is disposed in the annular flow path, a ring is disposed at the front end of the control sleeve in front of the flow guide structure such that the annular space is covered and sealed when the control sleeve is fully retracted into the annular space whereby flow losses are substantially reduced.
