摘要： A gasket-squeeze construction wherein a warp-limiter member is installed in a bolt hole in which a fastening bolt fits. The warp-limiter member is made less in an amount of flex than confronting surfaces, between which the gasket is disposed and squeezed by the tightening of the fastening bolt. The warp-limiter member serves to make the sealing stress uniform around a combustion gas hole. The warp-limiter member installed in the bolt hole, because of tougher to flex than the confronting surfaces when tightening the fastening bolt, makes uniform the clamping force of the fastening bolt and the compressive stress created around the associated bolt hole, moreover dispersing uniformly the sealing stress throughout around the combustion gas hole such as a cylinder bore, thereby rendering variation in distortion in the sealing joint less to improve the sealing performance.

摘要： A monolayer metal gasket is disclosed, which may be kept against deformation around a bolt hole and further made stable in sealing stress around a gas hole between mating surfaces of confronting components. A first extra thickness around the gas hole is provided by turning back a part of a metallic sheet on a major flat of the metallic sheet, with leaving a space open between them to form a folded construction having elasticity. A second extra thickness around a bolt hole is a closely layered construction of nearly rigid body little to be deformed. When the monolayer metal gasket is squeezed between the mating surfaces of the confronting components, a clearance between the mating surfaces may be regulated to a preselected distance by virtue of the second extra thickness that is little to be deformed.

摘要： In a metallic gasket having a metallic sheet made with a recess surrounding around a diverse type of hole, in which an elastic sealing member is installed, a relation between the recess and the elastic sealing member in their cross sections and also configurations is so specified as to use the elastic sealing member within a range of elastic limit inherent in the elastic sealing member, thereby improving the sealing performance of the metallic gasket. The elastic sealing member is smaller than the recess in their cross section perpendicular to the major side of the metallic sheet. Thus, the elastic sealing member, when the metallic gasket is squeezed, may serve its useful function within the range of inherent elastic limit.

摘要： A metallic gasket installed between confronting surfaces of engine components is improved in heat conduction between the components so as to reduce the adverse thermal influence to the engine. The metallic gasket used between the confronting surfaces of, for example a cylinder head and a cylinder block is composed of an annular raised portion defining inside a gas hole in alignment with an associated cylinder bore, and a surrounding metallic sheet connected to the annular raised portion. Both the annular raised portion and the surrounding metallic sheet are made of aluminum material to render the heat conduction between the components efficient. Thus the improved gasket can reduce the adverse thermal influence such as thermal deformation, thermal stress, and so on, whether the components are made of different materials or same materials.

摘要： A valve case includes an attaching portion and a sleeve. The valve case is attached to a cylinder head cover main body formed of resin. The attaching portion is formed of resin and is a portion of the valve case to which an oil control valve is to be attached. The sleeve is embedded in the attaching portion, and has an interior space that permits the oil control valve to be accommodated therein and oil holes. Each oil hole is selectively connected to one of ports of the oil control valve accommodated in the interior space of the sleeve. The sleeve is formed of material having higher rigidity than the resin forming the attaching portion. Therefore, the valve case prevents deformation of the attaching portion.
