Abstract
A metal gasket for a cylinder head includes a superposed assembly of an elastic metal base plate having a plurality of beads formed along a plurality of juxtaposed holes for combustion chambers, an elastic metal adjusting plate having a plurality of beads formed along a plurality of juxtaposed holes for combustion chambers, and a grommet having a plurality of juxtaposed holes for combustion chambers which are smaller in diameter than the holes in the base and adjusting plates. The grommet is folded about the edges of the holes in the adjusting plate lying between the base plate and the grommet in intimate contact therewith, so that the holes in the base and adjusting plates and the grommet may be aligned to form a plurality of bores. The bead on the base plate is formed as a full bead between every two adjoining holes and as a half bead around the remaining edge of each hole, while the bead on the adjusting plate is a full bead along the entire edge of each hole, so that the bead on the base plate may extend over the bead on the adjusting plate between every two adjoining bores.
