Between 14.Functional layer 12,14 each has opening 22, and opening 22 is sized to stop at least in part with wall 16
Opening 24 in region 17 is aligned, wherein opening 22 and 24 is each arranged to aligned with each other and has phase to be sealed accordingly
Answer passage 25 (such as cylinder-bore or exhaust outlet).Functional layer 12,14 each has compression seal convex tendon, and (such as full compression sealing is convex
Muscle 26), for example stretch out preset distance from the plane 28 of the general parallel orientation of layer 12,14, in order to set up surround it is sealed
The fluid of passage/gas-tight seal.The barrier zones 17 of wall 16 have to stretch out from each in opposite flank 18,20
Multiple raised 30 and extend inward into multiple depressions 32 of opposite flank 18,20.Corresponding projection 30 and depression 32 are straight each other
Connect relative so that each depression 32 on a side 18,20 for wall 16 is extended on the relative side of wall 16
Respective protrusions 30 in.There is " being thusly-formed " projection 30 the opposing parallel plane 33 from opposite flank 18,20 to stretch out
Height, it is slightly less than the height of " being thusly-formed " seal bead 26, and its protrusions 30 has rigidity, and the rigidity prevents close
