摘要： A cylinder head gasket 1 includes a shim ring 5 which surrounds a combustion chamber opening 2A in a gasket body 2. The shim ring is circumferentially spot welded along weld lines 5a, 5b. The weld spacing of the spot welding is varied to provide zones H.sub.1, H.sub.2 and H.sub.3 of high welding density and zone of a low welding density. The weld spacing in the zone of high welding density is such that a distortion in the shim ring is produced under the influence of heat generated during the welding operation if the weld spacing is used around the full circumference of the shim ring for spot welding. However, by interposing a zone of a low welding density, a distortion in the shim ring can be prevented while increasing the welding strength.

摘要： The invention is directed to an arrangement for sealing a clearance between a cylinder head and a cylinder block of an engine with a metal gasket clamped therebetween. The metal gasket is formed of a metallic base plate which has a plurarity of openings and beads formed therearound. The base plate may include annular shims welded on the base plate around the openings and a resilient sealing member deposited on the base plate surrounding the openings. The gasket may be disposed in such a manner as to place tip ends of the beads toward the cylinder block which causes a smaller displacement relative to the beads in comparison with the cylinder head. The resilient sealing member may be arranged to have a section of different dimension between a portion located at a side facing the beads and other portion at the opposite side thereof, or between a portion located at a junction where two of the beads meet and other portion.

摘要： The invention is directed to a metal gasket for sealing a clearance between a pair of clamping members. The metal gasket is formed of a metallic base plate on which at least one opening is defined. An annular metallic shim is welded on the base plate around the opening thereof. The annular metallic shim is disposed around the opening, and welded on the base plate by spot welding, forming a plurality of nuggets in series around the shim in such a manner that two adjacent nuggets overlaps each other and a space between those two nuggets is smaller than a diameter of each nugget.
