GASKET WITH A COMPRESSION LIMITER

摘要

A multi-layer gasket including first and second functional layers, each having an opening. Each of the functional layers includes a compression bead, and the compression beads contact and seal against one another when the gasket is compressed between a cylinder head and an engine block. At least one of the functional layers includes a stopper disposed between the compression bead and the opening. The stopper has a gear-like shape including a plurality of circumferentially spaced teeth. Each tooth extends upwardly from a plane by a distance which is less than the combined height of the compression beads. When the gasket is compressed between the cylinder head and engine block, the stopper ensures that the compression beads remain elastically biased against one another and maintain a gas-tight seal.
