First Claim
Patent Images
1. A variable capacity radial flow turbine comprising:
- a housing having therein a turbine wheel, a scroll-shaped working gas passageway leading from an entrance to said turbine wheel in a direction of working gas flow, an intake from said passageway to said turbine wheel, and a partition dividing said passageway into two parallel parts; and
means for adjusting the cross-sectional area of said two-part passageway and thus for smoothly changing the flow rate of working gas supplied to said turbine wheel, said means comprising a pivotally mounted vane for opening and closing said intake, said vane including a plate-like member having a downstream end in said direction of gas flow pivotally mounted adjacent the inner circumference of said passageway and an upstream end, and a rib extending from said plate-like member in a direction perpendicular thereto toward said partition.

Abstract
A variable capacity radial flow turbine includes a turbine housing which incorporates a turbine wheel and which forms a working gas passageway that leads to the turbine wheel and that is divided into two parts. The working gas passageway is provided with a pivotable plate-like member, so that the flow rate of the working gas flowing into the turbine wheel can be continuously changed by shifting the position of this member and thus opening or closing part of a working gas intake.
