摘要： A metal gasket for providing a seal between a cylinder head and a cylinder block of an engine is a laminate of a first metal plate, a second metal plate, and a third metal plate. The first metal plate has a folded portion for positioning around a cylinder bore, the second metal plate has a first full bead inside the folded portion to provide a primary sealing portion, and the third metal plate has a second full bead provided around an outer circumference of the first full bead to provide a secondary sealing portion. The primary sealing portion has a primary sealing surface pressure, and the secondary sealing portion has a secondary sealing surface pressure less than the primary sealing surface pressure. The secondary sealing portion provides enhanced following capability during engine operation.

摘要： A metal gasket for sealing multiple cylinder bores includes one or more metal substrates, main sealing beads around each of the cylinder bores, and one or more sub-beads. The main sealing beads include meandering portions located in a sealing portion between the cylinder bores, and the sub-bead is provided between the meandering portions. By placing the sub-bead between the main bead meandering portions, the base portion of the meandering portion and the base portion of the sub-bead squeeze each other. As a result, the lower portion of the meandering portion can be prevented from slipping, and the surface pressure can be partially reinforced. The metal gasket provides an excellent seal in a location where surface pressure is often partially reduced.
摘要翻译：用于密封多个气缸孔的金属垫圈包括一个或多个金属基底，围绕每个气缸孔的主密封珠和一个或多个子珠。主密封珠包括位于气缸孔之间的密封部分中的蜿蜒部分，并且在蜿蜒部分之间设置子珠。通过将子珠放置在主珠粒弯曲部之间，蜿蜒部的基部和副珠的基部彼此挤压。结果，可以防止蜿蜒部分的下部滑动，并且可以部分地增强表面压力。金属垫圈在表面压力通常部分减少的位置提供了极好的密封。

摘要： A metal plate for a gasket is provided with a plurality of beads around portions to be sealed. The beads intersect with each other to form an intersecting portion, which has a central portion, an outer portion outside the central upper portion and at least three side portion extending between side edges of the beads adjacent to each other. At least two side portions are curved to orient toward the intersecting portion and are located on or inside a part of an imaginary circular line. A radius of the imaginary circular line is at least twice as much as the width of the bead. Therefore, when the metal plate is tightened, the central portion is at first compressed to support the outer portion outside the central portion to thereby provide surface pressure substantially the same as that on the bead outside the intersecting portion.

摘要： The gasket of the invention is installed in an internal combustion engine having a hole to be sealed. The gasket is formed of first and second outer plates, and a middle member situated between the outer plates. A main sealing member formed of a wire ring is situated between a base portion of the first outer plate and the second outer plate around a curved portion of the first outer plate to define the hole of the engine. An auxiliary sealing member having a thickness less than that of the main sealing member is situated between the curved portion and the main sealing member. When the gasket is tightened, the main sealing member is compressed up to the thickness of the auxiliary sealing member to provide moderate surface pressure by the auxiliary sealing member near the hole and high surface pressure by the main sealing member away from the hole to be sealed. The surface pressure of sealing portions can be easily controlled.

摘要： A steel laminate gasket of the present invention is installed between two engine parts having at least one fluid hole. The gasket comprises a first plate having at least one first hole, a second plate situated above the first plate and having at least one second hole, at least one third plate situated above the second plate and having at least one third hole, and a cover member for covering at least first and third holes. The size of the first hole is smaller than the fluid hole of the engine parts to restrict flow rate of fluid passing therethrough. The second plate is provided with a first sealing device situated around the fluid hole such that the first sealing device is sandwiched between the two engine parts. The size of the second hole is smaller than the first sealing device. The size of the third hole is substantially the same as that of the first hole. The third plate is provided with a stepped portion, which is located inside the first sealing device when the plates are assembled together.

摘要： A cylinder head gasket for an internal combustion engine includes a first metal plate having first holes and first beads formed around the respective first holes, and a second metal plate disposed under the first metal plate and having a second bead extending toward the first metal plate. A distance between the first and second beads or a width of at least one of the first and second beads at a high heat load portion of the cylinder bore is formed to be greater than a distance between the first and second beads or a width of at least one of the first and second beads at a low heat load portion of the cylinder bore to thereby reduce a surface pressure at the high heat load portion.

摘要： In a cylinder head gasket, a base plate forming the gasket is formed of a first metallic material, and a grommet is provided around a hole for a cylinder bore and formed of a second metallic material different from the first metallic material. The grommet and the base plate are connected by welding. Accordingly, the grommet formed of the optimum material can be provided around the hole for the cylinder bore, and the base plate can be formed of the optimum material. Thus, the cylinder head gasket has a good sealing ability and excellent durability.
