摘要： A head gasket (48) which acts, when clamped between a cylinder head (28) and a block (22) in a liquid cooled internal combustion engine (20), to form a seal around the combustion chambers (24). A coolant flow path (32) routes through the engine (20) and its directed, in part, through the cylinder head (28) and the block (22), with a corresponding flow opening (54) formed in the head gasket (48) to accommodate flow of liquid coolant in a normal direction. The head gasket (48) includes a one-way valve (58) positioned in the flow opening (54) to allow the flow of coolant in a normal direction but to prevent the flow of liquid coolant through the flow opening (54) in an abnormal, reverse direction. The one-way valve (58) includes movable gate (66) which may be biased against a valve seat (64) in a normally closed condition. The one-way valve (58) can be made as a loose piece article of manufacture which is held in flow opening (54) by self-locking retention clips.

摘要： The subject invention provides a gasket for sealing multiple fluids and a method of forming the gasket. The gasket includes a carrier, a first elastomeric material, and a second elastomeric material different than the first elastomeric material. The first and second elastomeric materials are disposed in contact with the carrier in a flowable state such that the first and the second materials flow together to form a third elastomeric material comprising a mixture of the first and second elastomeric materials. The first and second elastomeric materials include cure systems that are compatible to ensure sufficient bonding within the third elastomeric material. Adhesive materials that are compatible with each of the first, second, and third elastomeric materials and the carrier are used to bond the elastomeric materials to the carrier.

摘要： A hydrodynamic PTFE seal for a rotating part including a first portion supported by a flexible, elastomeric member and a second portion extending from the first portion past the elastomeric member along the rotating part. The second or trailing portion of the seal is concentrically disposed about the rotating part. The first portion of the seal attached to the elastomeric member is also concentrically disposed around the rotating part. The seal can also include a living hinge portion disposed between the first and second portions. The first portion, the second portion and the living hinge portion can jointly define a continuous sealing surface.

摘要： A multilayer metal gasket, such as a multilayer steel head gasket, for an internal combustion engine has upper and lower functional layers and at least one intermediate layer. At least one of these layers has a circumferential compression control feature in the form of a protrusion or groove which varies in thickness or depth, respectively, around its circumference. The variable thickness of the compression control feature enables uniform sealing pressure on the sealing surfaces of the gasket.

摘要： An elastomeric seal (20), such as a shaft seal for automotive vehicle applications, includes an elastomeric compound (22) chemically coupled to a metal sealing ring (24) and is formed without an oven post curing step. The elastomeric seal (20) provides exceptional physical properties, similar to those of elastomeric seals of the prior art formed with an oven post curing step. The elastomeric seal (20) has an elastic modulus of 6.0 MPa to 13.0 MPa and a tensile strength of 11.1 MPa to 14.8 MPa. The elastomeric compound (22) includes 52.0 to 68.0 wt. % fluoroelastomer, 20.0 to 35.0 wt. % calcium silicate, and 5.0 to 15.0 wt. % diatomite. The elastomeric compound (22) is fully cured and chemically coupled to the metal sealing ring (24) during the compression or injection molding step, and thus an oven post curing step is not required.

摘要： A metal gasket includes embossments that exhibit essentially full functional recovery and full retained internal stress at temperatures up to about 1000° F. which is made from sheet material that is cold rolled and whose embossments are work hardened without any post embossment heat treating that would act to harden the material. This material may also receive a precipitation hardening heat treatment prior to being embossed. The gasket materials include alloys having greater than about 18% Ni, greater than about 14% Cr, from about 0.1 to 10% of at least one of Mo, Ti, V, Al, Co, Nb, Ta or Cu and the balance Fe with incidental impurities, which are cold rolled without any post embossment heat treating that would act to harden the material.
