摘要： A compression sensor gasket assembly and method of construction thereof is provided. The compression sensor gasket assembly includes a gasket body having opposite sealing surfaces extending between an outer periphery and an inner periphery with the inner periphery bounding a through opening. The gasket body has a passage extending from the outer periphery through the inner periphery and a pressure sensor assembly releasably attached to the gasket body in the passage and being configured to sense pressure within the through opening. The pressure sensor assembly can be removed from the gasket body in service without having to disassemble clamped members from clamped abutment with the gasket assembly. Further, the pressure sensor assembly can be routed over a curved path extending between the outer and inner peripheries to navigate about features that may be present in the gasket body.

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： 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 multilayer metal gasket (40) having first (28) and second (30) functional layers. Each layer (28, 30) includes an opening (34, 38) for sealing a fluid passage or combustion chamber. Each layer (28, 30) includes a folded lip or rim (50, 52) bent in opposite directions and overlapping one another in a nested configuration to form a labyrinth which serves also as the compression stopper feature for the gasket assembly (40). Sealing beads (42, 44) are formed in each layer (28, 30) and, preferably, are arranged to contact each other in crest-to-crest orientation to perfect a seal.

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.
