    • 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.
    • 气缸盖垫圈包括第一和第二相对的金属板盖板; 燃烧室开口由盖板中的对齐的孔形成; 以及分别设置在第一和第二盖板中的第一和第二小珠。 每个珠具有凸面; 第一和第二小珠的凸面朝向彼此。 第一和第二小珠彼此正交对准并且围绕燃烧室开口。 气缸盖垫片还具有定位在第一和第二盖板之间并与第一和第二小珠的凸面接触的间隔板。 间隔板具有与盖板中的孔大体对准的孔,并且由间隔板的边缘面限定。 还设置有位于间隔板的孔中的单独的环形插入件。 环形插入件被折叠以形成周向基部并且重叠,接触由基部部分互连并且径向向外定向的周向腿部部分,并在其外端处终止于间隔板的边缘面。
