摘要： PURPOSE:To reduce the manufacturing cost of a cylinder head gasket. CONSTITUTION:In the case of a series 6-cylinder engine cylinder head gasket 1, it is welded to shim rings 5 to surround combustion chamber ports 2A-2F respectively. While shim rings 5 at the positions of combustion chamber ports 2A, 2F that are on both end sides are welded in double line along their circumferential directions, the shim rings 5 that are other than these and are on a center side are welded in one line. As a result, the manufacturing cost of the cylinder head gasket 1 can be made inexpensive as compared with a case in which all the shim rings 5 are welded in double lines.

摘要： PROBLEM TO BE SOLVED: To improve the performance of sealing a three surface mating portion X, as compared with conventional one. SOLUTION: A liquid packing 7 is filled in a gap G of the three surface mating portion X to maintain sealing among an angular portion 3d of a cylinder head 3, an angular portion c of a cylinder block 2 and an end face 5B of a flange portion 5A. The angular portion 3d and the angular portion 2c are chamfered at preset angles to form chamfered portions 3e, 2d. An end 4B of a gasket 4 is protruded to the side of an end face 5B further than ends 3e', 2d' inward of the chamfered portions 3e, 2d. Thus, the liquid packing 7 is securely filled in the gap G with no clearance. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a gasket for an exhaust manifold used for an internal combustion engine. SOLUTION: The gasket is fitted integrally with a flange portion of a manifold, and includes a temporarily fitting element for positioning and mounting the gasket on the flange portion and a fall preventing element for preventing the gasket from falling off in positioning or mounting the temporarily fitting element. The gasket is mounted on the manifold by, first, engaging the fall preventing element with the flange portion to support it and fitting the temporarily fitting element to the flange portion or by a similar means.

摘要： PROBLEM TO BE SOLVED: To provide a gasket having low cost feature, and high durability and productivity comparing with a conventional gasket having graphite layers on its both surfaces, by forming a graphite layer G only on one surface of a gasket substrate 2. SOLUTION: The gasket 1 is grappled between an aluminum made cylinder head and a cast iron made cylinder block, and seals that part. The graphite layer G containing graphite is formed only on one surface of the gasket substrate 2 constituting the gasket 1, and a coat layer (rubber layer C) composed of material other than the graphite is formed on the other surface. The gasket 1 may be constituted by a plurality of gasket substrates. COPYRIGHT: (C)2003,JPO
