ABSTRACT:
A spring for radially biasing a slidable vane in an air motor vane slot includes two torsion coils, an offset base member connecting the coils and curved arm members extending from the coils. The offset base member reduces stress and allows a higher profile vane to be used. The arc shaped arm members redistribute wear or contact points and also allow a higher profile vane.
