Corrigan, C E; Dodge, P R

An apparatus is described consisting of: first annularly arrayed substantially immovable stator vane means for directing a flow of motive fluid onto a turbine wheel, the stator vane means being circumferentially spaced apart to substantially define a flow path therebetween having a determined flow area; second annularly arrayed guide vane means movably interdigitating with the stator vane means for selectively reducing the area of the flow path to an area which is less than the determined area; the stator vane means extending radially between concentrically arranged radially inner and radially outer portions of a housing, the housing portions cooperating the annularly bound flow path therebetween, the motive fluid flowing axially along the flow path, the radially outer portion defining a multitude of radially extending apertures opening to the flow path, the apertures movably receiving the guide vane means; the housing further defining annularly arrayed radially extending storage means communicating respectively with the multitude of apertures for receiving the guide vane means out of the flow path during flow of the motive fluid; and mechanical actuator means for moving the guide vane means between (1) a position wherein the guide vane means are disposed within the flow path to interdigiate with the stator vane means and extend radially between the radially inner and radially outer housing portions, and (2) position wherein the guide vane means are disposed within the storage means and removed from the flow path.
