Abstract
A cylinder head gasket includes a main gasket body having at least one cylinder opening, a wire sealing ring, and a metal armoring ensheathing the wire sealing ring. The metal armoring has a first annular flange portion extending beyond the cylinder opening in overlying relation to a first main surface of the main gasket body, a second flange portion opposite the first flange portion having a size no greater than that of the cylinder opening, and a curved portion joining the first and second flange portions. The cylinder opening is notched to receive lock tabs of the second flange portion through the main body, after which the metal armoring is rotated to offset the lock tabs from the notches to lock the armoring and sealing ring within the cylinder opening.
