Abstract
A spring assembly has a spring end for engagement with a component to bias the component in a first direction. The spring end is connected to a plurality of coils, which have an inner peripheral surface, and are mounted about a pivot pin. A damper is positioned between an outer peripheral surface on the pivot pin and the inner peripheral surface of the spring coils. The damper is engaged by the spring coils, if the spring end is driven in a direction opposed to the first direction. A one-way drive assembly and a gas turbine engine are also disclosed.
