Abstract
An improvement in a high thermal stress connection between a rotationally symmetrical component made of ceramic material and a component made of metallic material is provided in which a connecting part which is elastic and radially and axially resilient connects the ceramic part and the metallic part by means of high temperature soldering. The stresses normally produced by differential expansion of the ceramic part and the metallic part are substantially absorbed by elastic deformation of the connecting part.
