Abstract
The friction damper includes a hollow cylindrical member having an axially movable non-rotational member within the cylindrical member. A spring is disposed between the movable and cylindrical members. A rotating member lies within the cylindrical member in opposition to the movable member. A frictional resisting element resists relative rotation of the rotating member and the cylindrical member and causes the movable member to move axially away from the rotating member against the bias of the spring to increase the spring force of the spring and the frictional resisting force.
