  • Patent number: 10962101
    Abstract: A transmission case (10) includes a case (2) and a side cover (3). A rotation sensor (5) including a connector terminal part (52) is attached to the side cover (3). A seal member (FIPG) (4) is interposed between joining surfaces (22a, 32a) of the case (2) and the side cover (3). A notch portion (25) where the seal member (4) is accumulated is provided to an outer peripheral surface (22b) of the joining surface (22a) which is adjacent to the connector terminal part (52). Accordingly, the amount of the seal member (4) protruding outward from the outer peripheral surface (22b, 32b) of the flange portions (22, 32) is reduced, thus suppressing connection failure of a connector.

  • Patent number: 8814172
    Abstract: A cylinder head gasket 1 has a gas seal plate P1 in which a combustion chamber hole 11 is drilled, an oil seal plate P2 in which an oil hole 13 is drilled, and a main plate P3 provided between the gas seal plate and the oil seal plate. Plate thicknesses of the gas seal plate, the oil seal plate, and the main plate are made different from each other, the plate thickness of the gas seal plate is larger than the plate thicknesses of the oil seal plate and the main plate, and end portions of the gas seal plate, the oil seal plate, and the main plate are connected to each other. A combustion gas, lubricant oil or the like from a combustion chamber or an oil passage can be effectively sealed, and the cylinder head gasket can be manufactured inexpensively.

  • Publication number: 20140217679
    Abstract: A method of making a gasket having a high temperature coating that includes obtaining a substrate formed from a metallic material and having the shape of a gasket, applying a nanoparticle suspension over the outer surfaces of the substrate, and heating the substrate to a first elevated temperature to form an undercoat layer of a self-protective oxide coating. The method also includes applying a liquid comprising boron nitride over the undercoat layer and drying the boron nitride liquid at a second elevated temperature to form an overcoat layer.

  • Patent number: 8783692
    Abstract: A multilayer cylinder head gasket has a pair of functional layers and a distance layer with aligned openings. Each functional layer has a full bead located radially outwardly from and extending about its opening. Each functional layer also has a half bead spaced from the full bead. The distance layer includes a first portion extending radially from the opening and having a first thickness. A second portion of the distance layer extends radially from the first portion and has a second thickness that is less than the first thickness. A third portion of the distance layer extends radially from the second portion and has a third thickness less than the second thickness. The distance layer comprises a plurality of pieces, and at least one of the pieces limits compression of at least one of the full beads when the functional layers are compressed together.

  • Patent number: 8695986
    Abstract: A static cylinder head gasket assembly includes an inner distance layer having an opening extending between opposite planar sides with the opening being configured to register with a cylinder bore of an internal combustion engine. A plurality of inner functional layers overlie each of the opposite sides of the inner distance layer. The inner functional layers have axially aligned, nested annular sealing beads extending about the opening in the distance layer. The gasket assembly further includes a plurality of outer functional layers separate from the inner functional layers. The outer functional layers have annular inner peripheries spaced axially from one another to provide a gap configured to receive at least a portion of the inner distance layer therein. The outer periphery of the inner distance layer is captured axially between the outer functional layers and thus, the inner distance layer is prevented from being disassembled from the outer functional layers.

  • Patent number: 8672330
    Abstract: A sealing arrangement, which is particularly suitable for flat flange connections, has an annular, metallic base body (1). Connected to the metallic base body (1) at both sides are soft material supports (2). The base body (1) has ring teeth (3,4) which run around radially at the inside and/or at the outside. The ring teeth (3,4), in the installed state, permit punctiform metallic contact and also have a spring characteristic. The spring characteristic of the ring teeth (3,4) is selected such that, in a first embodiment, after the removal of the seal from the flanges, the tooth height corresponds substantially to the height before the installation. The region of the base body (1) which is covered by the soft material supports (2) also has angular ring teeth (5). The ring teeth (5) have a spring characteristic, wherein after the removal of the seal, the ring teeth (5) spring back to at least 75% of the original state.

  • Patent number: 8632077
    Abstract: A multilayer static cylinder head gasket has at least one metal functional layer and a metal distance layer having registered openings. The functional layer has a full bead located radially outwardly from and extending about its opening. The opening in the distance layer is formed in a first portion having a first thickness. A second portion of the distance layer extends radially outwardly from the opening and the first portion, wherein the second portion has a second thickness that is less than the first thickness. A compression limiter is formed in at least one of the functional layer or the distance layer. The compression limiter prevents the full bead from being completely flattened, which in turn maintains the full bead in high sealing pressure against the distance layer relative to the remaining portion of the functional layer and also prevents premature fatigue cracks from forming in the full bead.

  • Publication number: 20130320630
    Abstract: A gasket assembly is provided including a first gasket layer and a second gasket layer having an outboard region and an inboard edge circumscribing an aperture. The gasket layers present a sealing bead between the inboard edge and the outboard region. A stopper layer disposed between the gasket layers is attached to the outboard region of the first gasket layer at an attachment joint and extends from the attachment joint to the inboard edge. A coating of sealing material is applied between the first gasket layer and the stopper layer. The coating extends from the attachment joint to the inboard edge of the first gasket layer to present a contact region immediately surrounding the aperture where the first gasket layer and the stopper layer are in direct continuous contact with the coating thereby preventing gas leakage and metal to metal contact between the first gasket layer and the stopper layer.

    Abstract: A sealed t-joint includes a first component having a first sealing surface, a second component having a second sealing surface, and a third component including a channel characterized by a channel height, channel width, and a channel depth. The t-joint also includes a gasket having a thickness and a protrusion characterized by a protrusion height, a protrusion width, and a protrusion depth. The protrusion height is less than the channel height, the protrusion width is less than channel width, and the protrusion depth is less than the channel depth. The t-joint additionally includes a polymer sealant. The gasket is compressed between the first and second sealing surfaces to generate a first and second component sub-assembly. Additionally, the polymer sealant is applied into the channel. The third component is subsequently assembled with the first and second component sub-assembly such that the protrusion extends into the channel to seal the t-joint.
