ABSTRACT:
An adjustable stator vane assembly disposed in a fluid conduit of a turbomachine includes an annular outer shroud and an annular inner shroud positioned within and concentric to the outer shroud to form an annular fluid flow path. A plurality of rotatable stator vanes are positioned between the outer shroud and the inner shroud and spaced apart about the circumference of the inner shroud. Each rotatable stator vane has a vane shaft attached to one end thereof and a pivot pin supporting the other end thereof. A plurality of vane stem bushings are mounted in one of the inner shroud and the outer shroud, with each bushing receiving a respective vane shaft. The distal end of each vane shaft is connected through an individual linkage to a synchronizing ring. An actuator provide arcuate movement of the ring so as to simultaneously rotate each of the rotatable stator vanes.
