Abstract
A compound diaphragm bellows is provided that substantially increases the stroke of conventional viscous fluid dampers without significantly compromising radial stiffness. A method of restraining movement in a first plane while enhancing elastic movement in a plan perpendicular to the first plane is also provided. The disclosed compound diaphragm bellows are constructed by connecting alternating edges of flexible member pairs to rigid sleeves. Stiffening members may be added to enhance the compound diaphragm bellows' radial stiffness.
