ABSTRACT:
A spring support assembly for preventing compression instability displacement of helically coiled compression springs includes first and second support rings located at axially opposite ends of an arrangement of coil springs, the springs located at equal angular intervals about a longitudinal axis. Each support ring includes a support surface against which an end of each spring is supported, outwardly turned flanges located within each spring coil, and a tab extending partially along the length of the spring having close-fitting contact with the inside diameter of the spring coil. A support ring at the opposite end of the spring pack includes a support surface and tab angularly offset from the support surface, the tabs of each support ring located in adjacent compression springs.
