ABSTRACT:
A vane controller for a plurality of vanes disposed in a fluid conduit has vane shafts connected to the vanes and extending radially and spaced circumferentially around the conduit, and a control ring outside the conduit and movable circumferentially and connected to said vane shafts by levers to cause the vane shafts to rotate in unison to adjust the vane position. To reduce friction, the control ring is movable both circumferentially and axially and is preferably spaced from the conduit wall. A spherical bearing on the ring slidably receives a pin carried by each lever.
