摘要： This metal gasket comprises a pair of bead plates on which beads are formed so as to extend along the circumferences of combustion chamber holes, and an intermediate plate interposed between the bead plates. The intermediate plate is provided on the parts thereof which are closer to the combustion chamber holes than to the beads on the bead plates with stopper portions comprising stepped portions. These stopper portions constitute compensation portions for the beads on the bead plates. The compensation portions prevent a total compression of the beads on the bead plates when the metal gasket is tightened, offset the irregularity of opposed surfaces of a cylinder head and a cylinder block, improve the sealability with respect to the beads, and protect the beads against corrosion and compression.

摘要： The metal gasket according to the present invention is formed by bead base plates comprising elastic metal plates having beads and auxiliary beads along the circumferences of holes, and an intermediate plate interposed between these bead base plates. The stoppers and stepped portions formed on the intermediate plate prevent the total compression of the beads on the bead base plates when the metal gasket is tightened, and enable the irregularity of the opposed surfaces of a cylinder head and a cylinder block to be offset. The auxiliary beads provided on the bead base plates display the sealing performance with respect to the beads and minimize the dead spaces around the holes.

摘要： This metal gasket is formed by laminating a pair of bead plates and a pair of intermediate plates, and capable of setting the temperature distribution thereof uniform by efficiently cooling high-temperature regions which are in the vicinity of swirl chambers without causing a decrease in the rigidity and strength thereof. The portions of the bead plates which are in the vicinity of the parts thereof in which the swirl chambers are positioned are provided with coolant-contact areas surrounded by half beads formed on the bead plates, these coolant-contact areas being provided with holes. The wall surfaces of these holes directly contact the cooling water flowing in a water jacket in a cylinder head, and fulfil the function of radiating the heat transmitted from a high-temperature combustion gas thereto.

摘要： The present invention comprises a pair of bead plates on which beads are formed, and an intermediate plate on which first and second stepped portions are formed. One of the bead plates is provided with auxiliary beads so as to prevent a full compression of the beads and increase the sealability. This metal gasket comprises first and second bead plates having beads and extending along the circumferences of holes, and an intermediate plate interposed between the bead plates. The intermediate plate is provided in the regions thereof which extend along the circumferences of the holes and on the inner side of the beads with first stepped portions extending toward the first bead plate, and second stepped portions extending toward the second bead plate. The second bead plate is provided with auxiliary beads extending toward the second stepped portions. The auxiliary beads are adapted to engage the intermediate plate to increase the surface pressure and prevent the leakage of a high-temperature gas toward the beads on the first and second bead plates and the permanent set in fatigue of wing parts of the second stepped portions of the intermediate plate.

摘要： In this metal gasket, the beads formed on an intermediate plate prevent a full compression of bead plates and improve the sealability of the gasket. This metal gasket comprises first and second bead plates having main beads extending along the circumferences of holes, and an intermediate plate interposed between the first and second bead plates. The intermediate plate is provided in the regions thereof which are between the holes and the main bead-contacting portions thereof with beads opposed to the first bead plate, and these beads form compensating portions for the first bead plate. The second bead plate is provided with auxiliary beads having projecting portions engageable with the recessed portions of the beads on the intermediate plate. The compensating portions mentioned above prevent a full compression of the beads on the bead plates when the metal gasket is tightened, and offset the irregularity of the opposed surfaces of a cylinder head and a cylinder block. The auxiliary beads improve the sealability of the second bead plate with respect to the compensating portion-carrying intermediate plate.
