Abstract
An elastomeric compression including an elastomeric body defining a longitudinal axis and having two hollow convolutions between opposed ends of the spring. The convolutions are integrally formed and joined to each other by a connecting section. Each hollow convolution includes wall structure defining an outer surface for the spring. The wall structure of each convolution includes two angled wall sections disposed to opposed sides of the axis and which angle away from the connecting section and from each other. The outer surface of that portion of each angled wall section of each convolution adjacent to the connecting section has a projection extending outwardly from the outer surface. As such, and when the angled wall sections of one convolution collapse toward the angled wall sections of the other convolution, in response to a load being directed against the spring, the opposed projections on the convolutions contact and engage with each other thereby enhancing performance characteristics of the spring.
