摘要： A steel laminate gasket of the invention is installed in an internal combustion engine having at least one fluid hole and a plurality of bolt holes therein. The gasket basically comprises first and second plates for constituting the steel laminate gasket, and includes holes corresponding to the fluid hole and the bolt holes. A sealing device is formed around the fluid hole for sealing therearound when the gasket is tightened. At least one seal protecting member is integrally formed with the second plate. The seal protecting member extends from the second plate and is turned near the bolt hole to pile together with the first and second plates adjacent the sealing device. When the gasket is tightened, a part of the tightening pressure applied by the bolts is supported by the seal protecting member to thereby provide moderate tightening pressure to the sealing device.

摘要： A steel laminate gasket of the invention is installed in an internal combustion engine having at least one cylinder hole and at least one through hole. The gasket comprises a first plate, a second plate situated under the first plate and a third plate situated between the first and second plates. A first sealing device is formed on at least one of the first and second plates to seal around the cylinder hole of the engine. Also, a second sealing device is formed on at least one of the first, second and third plates to seal around the through hole. The third plate includes sealing layers on both sides thereof, and a hole so that the first sealing device is located therein when the gasket is assembled. Leakage around the cylinder hole and through hole is effectively prevented.

摘要： A manifold gasket assembly of the invention is installed between a manifold and a cylinder head. The manifold gasket assembly comprises a plurality of laterally spaced gasket structures, each having first and second plates with holes and a sealing device for sealing around the holes, and at least one connecting member integrally formed with the second plate for connecting the laterally spaced gasket structures. The connecting member includes a buffer member or a curved portion situated in the middle between the gasket structures. The buffer member or curved portion is situated away from the sealing device and the first plate, and is not compressed when the manifold gasket assembly is installed. The buffer member or curved portion operates to absorb the change of the distance between the gasket structures due to heat of the engine.

摘要： A steel laminate gasket comprises a first plate having at least one first hole, a second plate situated adjacent to the first plate, and at least one depression formed either on the first plate or the second plate and extending toward the other. The second plate is provided with at least one second hole and a bead extending around the second hole. The bead extends substantially perpendicularly to a horizontal plate of the second plate toward the first plate to abut against the first plate. Height of the depression is substantially the same as or slightly less than that of the bead so that when the first and second plates are connected together by a spot welding at the depression, the first and second plates are maintained substantially parallel to each other.
摘要翻译：钢层压垫片包括具有至少一个第一孔的第一板，与第一板相邻的第二板，以及形成在第一板或第二板上并向另一个延伸的至少一个凹陷。第二板设置有至少一个第二孔和围绕第二孔延伸的胎圈。胎圈基本上垂直于第二板的水平板朝向第一板延伸以抵靠第一板。凹陷的高度与珠的大小相同或略小，因此当第一和第二板通过在凹陷处的点焊连接在一起时，第一和第二板基本保持彼此平行。

摘要： A gasket comprises a main body having at least one opening and a plurality of elastic members provided on at least one of upper and lower surfaces of the main body. The elastic members project outwardly from the upper or lower surface. The characteristics of at least one of the elastic members are different from those of the others. The elastic members surround the opening so that when the gasket is compressed between two parts, the elastic members deform to thereby securely seal around the opening.

摘要： A steel laminate gasket designed to efficiently seal engine parts having high and non-high pressure areas. The gasket comprises a core plate extending throughout entire area of the engine to be sealed, at least one metal plate situated above the core plate, and at least one soft sheet situated above the core plate. The metal plate is placed adjacent to the high pressure areas of the engine so that the high pressure areas of the engine are sealed by the core plate and the metal plate. The soft sheet is made of a soft gasket material and is placed adjacent to the non-high pressure area so that the non-high pressure areas of the engine are sealed by the core plate and the soft sheet.

摘要： A gasket includes a plurality of metal plates laminated together, and having a plurality of through holes situated adjacent to each other, and seal structures each annularly surrounding each of the through holes. Each of the seal structures includes a first seal bead adjacent to one through hole and a second seal bead situated outside the first seal bead relative to the one through hole, a first seal portion located in a first area between adjacent two through holes, and a second seal portion located in a second area other than the first area. The first seal portion has an annular width narrowing as outside ends of the first seal portion come close to a center of the first seal portion by locating the second seal bead close to the first seal bead, and the second seal portion has an annular width constant in an annular circumferential direction.
