摘要： Disclosed is a hermetically sealed assembly for precompression of a martinsetic metal for use in negative pressure energy transfer systems, and method of making same. The assembly comprising a martinsetic metal disposed between and in contact with flanged sapphire windows, the flanges defining an open area therebetween to accommodate expansion and contraction of the martinsetic metal. Hermetic sealing means include a bellows element, which can comprise a convoluted cross section, at the periphery of the assembly to enable operation over temperature ranges from ambient to cryogenic without loss of integrity or leakage.

摘要： A metal sealing ring (1) for forming a metal-to-metal seal between two opposing metal surfaces. The metal sealing ring (1) comprises a tubular metal body (3) and an inlet tube (7) extending from the body (3) for introducing an internal pressure into the body (3). The body is adapted to deform under the internal pressure against each of the opposing metal surfaces to form the seal (1).

摘要： A ring-shaped gasket for making high-purity fluid pathway connections between opposing fluid delivery apparatus elements having at least one simple flat surface in contact with the gasket. The face of at least one apparatus element typically has a circular counterbore depression to receive the gasket, but is not required. The gasket has a body, pierced through by a hole creating a fluid pathway and defining a radial inner surface, and additionally having a radial outer surface, a first axial end surface and a second axial end surface. At least one of the first and second axial end surfaces has a stress concentration feature radially adjacent to a gasket sealing region, the sealing region constructed to be in contact with a face surface of a corresponding fluid conduit port. The stress concentration feature may be a groove or a plurality of cavities disposed adjacent the gasket axial end surface sealing region.

摘要： A seal structure has a metal gasket arranged between a pair of casings. The metal gasket is provided with a bead portion in an inner peripheral side of a planate outer peripheral portion, and a bent portion in an outer peripheral side. When the metal gasket is pinched by a pair of casings, the bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, and comes into contact its outer peripheral end portion with one casing, whereby any gap in which salt water stays is not formed between one casing and the outer peripheral portion, and the bent portion comes into contact with the other casing, whereby any gap in which the salt water stays is not formed between the other casing and the outer peripheral portion.

摘要： Each of ridges 7 on respective opposite side surfaces of a gasket 4 has a trapezoidal cross sectional shape defined by an outer tapered face 7a providing an outer peripheral surface, an inner tapered face 7b providing an inner peripheral surface and a flat face 7c providing a top end surface. The hardness of the gasket 4, the angle between the tapered faces 7a, 7b of the ridge 7, the height of the ridge 7 and the area of the flat top end face 7c of the ridge are so determined that the value of thrust for tightening up the coupling is between a predetermined minimum value and a predetermined maximum value.

摘要： Disclosed is a metal seal ring by which conduits are hermetically engaged by a pressure in accordance with a fluid pressure. The metal seal ring is comprised of a first annular seal surface (12a) configured so as to be in contact with a first flange, a second annular seal surface (12b) configured so as to be in contact with a second flange, a pressure receiving surface (12f) which is formed between the first and second seal surfaces and which defines an annular recessed portion (12e) which is radially inwardly open, and an annular seal portion (12) comprised of a first seal portion (12A) which is elastically deformable and formed between the annular recessed portion (12e) and the first seal surface (12a) and a second seal portion (12B) which is elastically deformable and formed between the annular recessed portion (12e) and the second seal surface (12b). An annular seal ring main body (14) which is engaged with the first and second flanges to prevent the first and second flanges from moving closer to the metal seal ring in the axial direction and prevent an excessive force from being applied to the first and second seal portions, is provided on the radially outer side of the seal portion (12). The first and second seal portions (12A, 12B) are respectively pressed against the first and second flanges due to the fluid pressure received by the pressure receiving surface.

摘要： A disclosed connector assembly for a refrigerant system mounted within an aircraft includes a metal seal disposed within a seal bore of a connector and compressed against a seal face of a nipple secured to the connector by a threaded member. The connector includes a seal bore that receives the metal seal with the inner portion of the seal bore open to the bore. In one example, the connector and nut are formed from aluminum and the nipple is formed from stainless steel and includes an aluminum coating applied to surfaces in contact with the metal seal and the connector.
