Cylinder head gasket with peripheral bead

DRIVE January 29, 2003

A cylinder head gasket (1) is formed of a metal plate (3), a sealing bead (19) formed in the metal plate around a liquid hole, and a peripheral bead (17) formed in the metal plate to extend around a periphery of the metal plate. At least a part of the peripheral bead is set to have a surface pressure lower than that of the sealing bead when the gasket is tightened by that the height (h1) of the peripheral bead is lower than that (h2) of the sealing bead or the width (w1) of the peripheral bead is greater than that (w2) of the sealing bead. Thus, when the gasket is tightened, substantially uniform and optimum load share can be obtained on the peripheral bead and the sealing bead for the fluid hole.
