ABSTRACT:
An apparatus to compensate for the thermal expansion of a component inserted between two elements, particularly an explosive member placed between a lining, and a cover plate in a shaped charge, comprises two rings that are in contact with one another through conical inner and outer surfaces. The ring with the conical outer surface is made of a material that has a lower coefficient of thermal expansion than the material of the ring with the conical inner surface. So that the apparatus expands upon reduction in temperature and contracts upon increase in temperature to compensate for respective contraction and expansion of the component.
