RADIALFLUSSTURBINE MIT VARIABLER KAPAZITAET.

摘要

A housing having in it a turbine wheel and a scroll-shaped working gas passageway leads from an entrance to the turbine wheel in a direction of working gas flow. An intake is provided from the passageway to the turbine wheel. A partition divides the passageway into two parallel parts. An assembly is provided for adjusting the cross-sectional area of the two-part passageway and thus for smoothly changing the flow rate of working gas supplied to the turbine wheel. The assembly comprises a pivotally mounted vane for opening and closing the intake. The vane includes a plate having a downstream end in the direction of gas flow, pivotally mounted adjacent the inner circumference of the passageway and an upstream end. A rib extends from the plate in a direction perpendicular to it toward the partition.
