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.
