The gasket has multiple stacked sheet metals with openings (32) coinciding with a combustion chamber, and an orifice (34). A stopper (30) has an interleaving sheet metal. The stopper has resistance to variable deformation along its circumference, such that zones of the stopper that are very close to the orifices have lower resistance to deformation than the zones that are away from the orifices.
