    摘要: A cylinder head gasket (1) for an internal combustion engine is formed of a metal plate (10, 10b) extending substantially throughout an entire area to be sealed. The metal plate has a plurality of holes (2) corresponding to cylinder bores of the engine, a plurality of beads (3) surrounding the respective holes, and at least one area (W) situated between the holes adjacent to each other. Seal coatings (4, 4') are deposited above the beads (3) in the area. The seal coating has heatproof characteristic and compressibility to strengthen the surface pressure of the beads at the area.

    摘要: A cylinder head gasket (1) of the invention is used for an internal combustion engine with at least three cylinder bores (2). The gasket is formed of a metal plate (10) extending substantially throughout an entire area to be sealed, and a reinforce coating (4b). The metal plate includes two end holes, at least one inner hole sandwiched between the two end holes, and beads (3a, 3b) surrounding the respective holes. The two end holes and at least one inner hole are arranged linearly to correspond to the cylinder bores of the engine. The reinforce coating (4b, 4c) is deposited around the peripheral portion of the at least one inner hole so that sealing pressures are formed substantially equally around the two end holes and at least one inner hole. Other reinforce coatings (4a) may be deposited around the peripheral portions of the end holes.

    摘要: A metal gasket (1) is formed of a metal base plate (10) for sealing between two members. The metal gasket (1) has a bead (12) around a cylinder bore (2) and a bead (13) around a fluid hole (3) on the metal base plate (10). Coatings (30a, 30b) are applied on both surfaces of the beads (12, 13), respectively. When the metal gasket (1) is tightened, strong sealing surface pressures are locally generated at sealing line portions (A, B, C) of the beads (12, 13). The coatings (30a, 30b) are applied only on other portions except for the sealing line portions (A, B, C).

    摘要: A cylinder head gasket (1) for an internal combustion engine is formed of one metal plate (10) having a base portion extending substantially throughout an entire area to be sealed, a hole (2) formed in the base portion corresponding to the hole of the engine, and a bead (11) surrounding the hole. A resin coating (20a-20f) is deposited on at least a part of the bead of the metal plate. Thus, the bead is reinforced and sealing ability is improved.

    摘要: A metal laminate gasket (A, B) of the invention is used for an internal combustion engine. The gasket is formed of a plurality of metal plates (A10, All, A12; B10, B12) for constituting the metal laminate gasket, wherein each metal plate has a hole (Hc) corresponding to a fluid hole of the engine. A bead (A12a, B12a) is formed on one of the metal plates to surround the hole for sealing therearound. Outer surface layers (A13, B13) are coated on outer surfaces of the metal laminate gasket, and at least one inner surface layer (A14, B14) is coated on at least one of inner surfaces of the metal plates. The outer surface layers (A13, B13) are formed of a material containing rubber to closely contact the gasket to the engine parts, and the inner surface layer (A14, B14) is formed of a material containing resin to provide sliding ability between the metal plates. The gasket (A,B ) can securely seal between the engine parts.
