Here are some design drawings of an updated design that eliminates the need for the spring in the linkage rod by always allowing the accelerator lever to return to idle regardless of vane position and boost can position".

Pics are in ( I think) : http://s13.photobucket.com/user/libbyba ... t=3&page=1

Does he mean pics with white background (can with tangential moving) or the ones with black background ( can with axial moving, often seen in other control systems, Libby, Rock3tman) ?
Has the "tangential moving can ever been built? Result?

I moved my question here in hope someone can give a hint.

Yes, the tangential movement would eliminate the need for the spring in the rod.  Nope, never built it.

Thanks Libby!
I have made some remarks on your drawing. Are they okey?


My VNT lever works in oposite direction to your drawing so I have to swing the can around.

It would need some sort of guide bushing. 

With a cable vs. solid linkage rod, what will push the vanes to the open position?
