Abstract
The invention is concerned with an absorbing spring involving the hydrostatic compression of an elastomer, comprising a tight casing constituted by a deformable, bent elastic tube of flattened section, filled with elastomer. A central core is embedded in the elastomer, the core being made of elastic material, the coefficient of heat expansion of which is lower than that of the tube. The invention finds particular application in the manufacture of absorbing devices.
Claims7
An absorbing spring which comprises:
- a metallic core embedded within an elastomer;
- and
- a deformable elastic tube of flattened section tightly and totally encasing said elastomer, said elastomer being subject to hydrostatic compression forces and having a coefficient of heat expansion lower than the coefficient of heat expansion of said elastic tube thereby conserving the substantially constant operational characteristics of the spring.
