According to some embodiments, a multi-layer gasket with a non-compressible core, formed of any material that is relatively rigid and incompressible and can serve as a carrier for a gasket, and compressible layers, formed of any flowable or compressible sealing material with appropriate rheology for a particular sealing application, in the form of edge or surface coatings, is presented.

An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

A gasket for an internal-combustion engine is designed to seal between an engine block and a cover of the internal-combustion engine. The gasket includes a plurality of members that are metal and a layer of elastomeric material on the members. The elastomeric layer includes joints between the members. The joints allow the gasket to flex to accommodate potential variation in sealing surface of the engine block without bending of the members.

A flat gasket, comprising a support body, wherein the support body has at least two segments which are fixed to one another in a positive-locking manner, wherein the segments each have two main sides, wherein a sealing contour is arranged on at least one main side of each segment.

A multi-layer steel gasket includes a pair of outermost steel layers having a plurality of combustion openings. The outermost layers are generally planar and free of elastic beads in a compression region of the gasket immediately surrounding the combustion openings. A pair of metal sealing rings are associated with each of the combustion openings and are disposed between the outermost layers and are formed with opposed full beads that face away from one another in the compression region of the gasket around each cylinder opening. The sealing rings each having a thickness of at least 0.3 mm and which is greater than a thickness of the outermost layer. At least one distance layer is disposed between the outermost layers, wherein when the compression region is fully compressed, the thickness of the combined layers of gasket in the compression region is greater than the thickness of the combined layers of the gasket in a body of the gasket adjacent the compression region.

An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

A gasket material to be mounted in a vehicle engine, wherein, on one or both sides of a steel plate, a rubber layer is formed via a coating film including a reaction product of an acid component and a metal or a reaction product of an acid component and a metal compound, and at least one selected from zirconia, alumina and titania.

The invention relates to a patient ventilation or breathing device and components therefore for use in all forms of respiratory apparatus ventilation systems including invasive and non-invasive ventilation, positive airway pressure therapy, Continuous Positive Airway Pressure (CPAP), and particularly Bi-Level therapy and treatment for sleep disordered breathing (SDB) conditions such as Obstructive Sleep Apnea (OSA), and for various other respiratory disorders and diseases. The invention particularly relates to a blower, to a blade, to a gasket, to a cable, to an impeller, to a gas inlet and inlet member, to an improved air path or fluid flow path and components thereof, and/or to a modular ventilation or breathing device as referred to above and particularly incorporating one or more of the other aspects of the invention.

A layered head gasket includes a gasket core, a head-layer, a block-layer, and a plurality of apertures. The head gasket may be useful for sealing an internal combustion engine having a cylinder head, a cylinder block, a plurality of combustion chamber passageways, a plurality of coolant passageways, and a plurality of oil passageways. The gasket core is made of a copper sheet. The head-layer may be made of spring steel and may be fixed to a top side of the gasket core, being configured to interface with the cylinder head. Likewise, the block-layer may be made of spring steel and may be fixed to a bottom side of the gasket core, being configured to interface with the cylinder block. The plurality of apertures may pass through the head-layer, the gasket core, and the block-layer.
