| 20080197577 | Integrated Exhaust Manifold and Cylinder Head Gasket - A gasket assembly for an internal combustion engine having a cylinder head gasket and an exhaust manifold gasket. The cylinder head gasket and the exhaust manifold gasket have a common layer of gasket material. The gasket assembly is formed by stamping a cylinder head gasket portion for the engine in one region of a common layer of gasket material concurrently with stamping an exhaust gasket portion for the engine in an adjacent region of the common layer of material. | 08-21-2008 |
| 20080272549 | GASKET CONTAINING FUEL PERMEATION BARRIER - A method for reducing fuel permeation through gasketed joints in an internal combustion engine ( | 11-06-2008 |
| 20090033035 | Cylinder head including a stress slot with filler - A seal for an engine is disclosed. The seal may include a cylinder head gasket. The seal may also include a cylinder head having a top surface and a bottom surface, the bottom surface of the cylinder head attached to the cylinder head gasket. The seal may also include a plurality of adjacent openings extending through the cylinder head, from the top to the bottom surface. The seal may further include one or more elongated slots in the bottom surface of the cylinder head, the one or more slots being located between at least two of the adjacent openings and extending between the openings. The seal may also include filler material filling each of the elongated slots. | 02-05-2009 |
| 20090315268 | Radial Crimp Seal - A sealed joint for a gas sensor as described which includes a sensor shell having an attachment portion and a sealing portion. The sealing portion has an inner recessed section and an outer protruding section terminating at a free end of the shell, the outer protruding section having an outer section diameter which is greater than the diameter of the inner section. The sealed joint also has an upper shield having a shell portion disposed around the sealing portion of the shell and a connector portion which extends upwardly away from the shell portion. The sealed joint includes a first radial crimp of the upper shield proximate the inner recessed section and a second radial crimp of the upper shield in the connector portion proximate the shell portion, such that the second crimp has a crimp diameter which is less than the outer section diameter of the shell. The structure described has a sealed joint between the sealing portion of the shell and the shell portion of the upper portion located between the first crimp and the second crimp. | 12-24-2009 |
| 20100127460 | SEALS WITH INTEGRATED LEAK DETECTION CAPABILITY - In one embodiment of the invention, a seal device is provided with integrated leak detection capability for detecting the initiation of a leak of a contained fluid and includes a seal member having at least one sealing contact surface and a sensing member located on the sealing contact surface, the sensing member detecting if a breach has occurred in a seal formed between the sealing contact surface and a member against which the sealing contact surface is sealed to provide an indication of the breach before a complete breach of the seal occurs; and a deposit of electrically conductive particulates on the seal member located between the contained fluid and the sensing member. | 05-27-2010 |

| 20120056382 | Method and Apparatus for Installing an Engine Seal - A method and an apparatus for installing an engine seal include the steps of removing the existing seal and repositioning a replacement seal therein. A varying-diameter sleeve is compressed, inserted into the replacement seal and released. A telescoping pipe is inserted into the sleeve and extended until the seal is perfectly seated within a designated groove. | 03-08-2012 |
| 20130082444 | Service Gasket For Internal Combustion Engine And Method - A service gasket includes a one-piece laminate body having a plurality of low pressure seals positionable between an engine head and an engine block, and a high pressure combustion seal positionable between the engine head and a sealing surface of a protruding cylinder liner. The one-piece laminate body further includes a plurality of pervasive base layers extending from the outer perimeter to the inner perimeter, and at least one non-pervasive service layer located outwardly of the inner radial region, such that the service gasket has an outwardly stepped-up thickness compensating for increasing a protrusion distance of a sealing surface of the cylinder liner during servicing the internal combustion engine. | 04-04-2013 |
| 20140042705 | MULTI-LAYERED GASKET - A gasket having a first upper layer, a second lower layer and a spacer layer is provided. The first upper layer has a bead located between two lands. The second lower layer also has a bead located between two lands. The spacer layer has an embossment located between two lands. A coating may be located within the embossment. The beads are located in an axial relationship with respect to the embossment. | 02-13-2014 |
| 20140091528 | SEALED ASSEMBLIES AND METHODS OF UNSEALING SAME - A sealed assembly includes a first component having a first flange, and a second component having a second flange matable with the first flange. The sealed assembly also includes a sealant disposed between and along the first flange and the second flange such that the first component is sealingly mated to the second component. The sealed assembly further includes a wire disposed within the sealant, wherein the wire is configured for unsealing the second component from the first component. A method of unsealing the sealed assembly is also disclosed. | 04-03-2014 |
| 20140138917 | One Piece Oil Pan Gasket - Kits and methods of sealing an engine oil pan to its respective engine block by using a molded gasket of removable type that fits between the oil pan and engine block and timing cover. A removable gasket that fits between the oil pan and engine block and timing cover that does not require silicone sealant for fastening the oil pan to the engine block. | 05-22-2014 |
