摘要

The cylinder head joint has an opening (14) corresponding to a combustion chamber and comprises two outer metal sheets (12) at least one of which has a circular rib (16) surrounding the opening. A metal sheet support (18) located between the outer sheets has an opening of greater diameter than the outer sheets opening in order to define a space in which an annular wedge shaped stopper (20) is located. The stopper has a diameter greater than that of the ribs.
