Abstract

A static gasket configured for establishing a seal between a cylinder head and an engine block including at least one layer having an opening and at least one compression bead. The compression bead extends circumferentially about the opening and projects out of a plane for deforming elastically when the gasket is compressed between the cylinder head and the engine block. A compression limiter which is formed from a metal wire is disposed radially between the opening and the compression bead for preventing the compression bead from being fully flattened, even if the cylinder head is overloaded onto the engine block. The compression bead is preferably induction and/or resistance welded to at least one of the layer(s).

Claims (3)

1. A static gasket configured for establishing a seal between a first member and a second member, comprising:

at least one layer having at least one opening and at least one compression bead projecting out of a plane and extending circumferentially about and spaced from said at least one opening; and

a compression limiter disposed radially between said opening and said compression bead of said layer, and wherein said compression limiter is a work hardened, flattened metal wire having substantially planar opposite sides which is induction or resistance welded to said layer, wherein said compression limiter has an annular groove and said layer has an annular lip disposed in said annular groove, wherein a portion of said compression limiter extends radially inwardly from said layer into said opening in substantially flush relation with one side of said layer.
