ABSTRACT:
The spring includes a composite elastomeric body having in one embodiment a closed end and an open end. A coil spring is embedded both within the body wall and the closed end, and provides reinforcement of both the body wall and the closed end. The body may be of cylindrical, conical, or other shape, depending upon the required function of the spring. It may also take an essentially hourglass shape or the shape of a cylinder flanged at both ends. Alternately, the spring may be internally pressurized to provide load leveling or air spring effects in addition to the variable rate load versus deflection curve normally obtained. The body may be attached directly to any surface to create an airtight seal. Alternately, a closure plate may be provided to seal an open end of the coil spring.
