ABSTRACT:
A ceramic cap is attached to a metal piston by means of intermeshing radial flanges. A spring forces the flanges into contact with one another along an annular surface area. Spaces between the flanges allow for movement between the metal and ceramic parts to accommodate differential thermal expansion, while at the same time permitting secure contact between metal and ceramic.
