Vane controller
First Claim
1. A vane controller for a plurality of vanes disposed in a fluid conduit having a bounding wall and an outer surface of said wall, said vane controller havingvane shafts connected to the vanes and extending radially and spaced circumferentially around the conduit,levers having first ends connected to said vane shafts and second ends,a control ring outside the conduit and movable both circumferentially and axially and connected to said second ends of said levers whereby movement of said ring moves said levers in unison to rotate the vane shafts and thereby adjust the vane positions, said control ring having an outer periphery,wherein said control ring is spaced from the said outer surface of said wall of the conduit and is provided with support means acting upon its outer periphery.

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.
