4. A heat shield according to claim 1 wherein
said projection is adjacent to said overlap; and
said overlap is annular.
5. A heat shield according to claim 4 wherein
said gasket surrounds said overlap at a constant radial distance.
6. A heat shield according to claim 1 wherein
said second shield component is provided with cover surfaces bent at least partially on a side edge thereof; and
said first and third shield components have similar shapes, and hold said second shield component therebetween along common contact surfaces.
7. A heat shield according to claim 6 wherein
said second shield component has several layers; and
said first and second shield components are each a single layer of sheet metal.
8. A heat shield according to claim 7 wherein
said second shield component has an insulating intermediate layer.
9. A heat shield according to claim 1 wherein
said overlap extends along said common connecting line by said third shield component encompassing said second and first shield components.
10. A heat shield according to claim 1 wherein
said shield components are held within said overlap by frictional engagements allowing displacement relative to one another in a compensation distance.
11. A heat shield according to claim 1 wherein
additional passage openings extend congruently through said shield components.
12. A heat shield according to claim 1 wherein
said projection is part of said first shield component and extends in a direction away from said second shield component.
13. A heat shield according to claim 12 wherein
said third shield component includes another projection forming said gasket and extending in a direction away from said second shield component.
14. A heat shield according to claim 1 wherein
said connecting line extends along said passage opening.
15. A heat shield according to claim 1 wherein
each said shield component has a planar portion in direct contact with said planar portion on an adjacent one of said shield components.
16. A heat shield according to claim 1 wherein
said overlap extends through said passage opening.
17. A heat shield according to claim 1 wherein
said projection extends in a direction away from said second shield component.
18. A heat shield according to claim 1 wherein
said projection comprises first and second projections extending from said first and third shield components, respectively, in directions away from said second shield component.
19. A heat shield according to claim 1 wherein
said overlap extends through said passage opening and over a surface of the other of said first and third shield components remote from said second shield component.
