Abstract
A cylinder head gasket includes first and second opposite sheet metal cover plates; a combustion chamber opening being formed by aligned apertures in the cover plates; and first and second beads provided in the first and second cover plates, respectively. Each bead has a convex side; the convex sides of the first and second beads are oriented toward one another. The first and second beads are in an orthogonal alignment with one another and surround the combustion chamber opening. The cylinder head gasket further has a spacer plate positioned between the first and second cover plates and is contacted by the convex side of the first and second beads. The spacer plate has an aperture which is in general alignment with the apertures in the cover plates and is defined by an edge face of the spacer plate. There is further provided a separate annular insert positioned in the aperture of the spacer plate. The annular insert is folded to form a circumferential base part and superposed, contacting circumferential leg portions interconnected by the base part and oriented radially outwardly and terminating, at outer ends thereof, at the edge face of the spacer plate.
