Double-flow turbine housing for exhaust gas turbocharger of e.g. internal combustion engine, has guide vane arranged in transfer region between spiral channel and space, and intermediate wall sectionwise integrally designed with vane

摘要

The housing (10) has spiral channels (12, 16) coupled with an exhaust manifold of a drive unit. One of the channels is delimited by the other channel by an intermediate wall (14). A turbine wheel (18) is arranged downstream to the spiral channels in a receiving space and loaded with exhaust gas. The wheel is rotatable around a rotational axis (A). A guide vane (20) is arranged in a transfer region between one of the channels and the receiving space. The intermediate wall is sectionwise integrally designed with the vane. An independent claim is also included for a method for manufacturing a turbine housing for an exhaust gas turbocharger of a drive unit.
