An isolation component for vibratory equipment such as a vibratory trough or feeder includes an isolation spring for supporting the dynamic load of the equipment, and a damper element, preferably an elastomeric ring, arranged against an end of the isolation spring. The damper element prevents excessive motion of the isolation spring due to the vibratory equipment's operating frequency being close to any of the natural frequencies of the bending mode of the isolation spring by applying an opposing load to any such motion. The damper element is preferably an elastomer ring and is arranged along an axis of the support spring. A connector extends from a first end of the isolation spring, adjacent the damper element, toward and past a second end of the isolation spring and is connected to the vibratory equipment. The second end of the isolation spring is supported by a housing supported by external structure such that the weight and dynamic load of the equipment compresses and expands the isolation spring, and excessive expansion of the support spring acts on damper element which is braced against the housing.

[ What is claimed is:] [1.] A vibration isolation component for connecting a vibrating structure to a relatively non-vibrating structure comprising:a spring having a first end and a second end, said spring being compressible and expandable along an axis between said first and second ends, said spring arranged to support the vibrating structure from the non-vibrating structure; anda damper element arranged adjacent one of said first or second ends and arranged to impart a resilient force opposing expansion of said spring, and to impart a resilient force for compression of said spring, expansion of said spring causing compression of said damper element and compression of said spring allowing expansion of said damper element, said spring and said damper element being arranged for the spring to support the vibrating structure at a position located between the spring and the damper element.
