An improved hydrostatically compressed elastomeric spring in which an inner metal core buried in the elastomer contained in a flattened and bent tube constitutes a heating resistor for the elastomer to control its expansion and the compression of the spring under the effects of a static load. The spring is useful in shock absorbing devices.
