<p>Lining of an element, which constitutes an outer casing (2), by means of another element which constitutes an inner lining (1) for the casing and wherein the materials in the two elements have different coefficients of thermal expansion and wherein the lining is characterized in that the linear expansion of the two elements is adapted to emanate from one single common fixed point (5), and that all contact points between the two elements are positioned on an imaginary cone or a polygonal pyramid, the tip of said cone or pyramid coinciding with said fixed point (5), such that said contact points between the two elements are located on the generatrices (4a-4e) of the said cone, and under relative linear displacements, caused by temperature changes in any of the elements, the contact points have been given a possibility of moving freely along the generatrices through the respective contact points.</p> |
