  • Patent number: 7429065
    Abstract: An assembly includes a first member having an inner surface and a second member having an outer surface. One of the two members has greater rigidity than the other member and at least one groove. The rigid member is partially received within the less rigid member and a coupling mechanism provides radially inward pressure to generate a seal between the inner surface of the first member and the outer surface of the second member. The groove includes an opening and a base each having a predetermined width. The predetermined width of the opening is generally less than the predetermined width of the base. The more rigid member may comprise an insert with a surrounding sleeve wherein the sleeve includes the grooves.

  • Patent number: 7334308
    Abstract: A body mount support bracket, including a central body portion having a pair of leg portions depending therefrom, is secured to a frame portion of a vehicle body and frame assembly by flexing the leg portions from a first, unstressed position to a second, stressed position so as to create internal stresses within the body mount support bracket. Then, the central body portion and the leg portions of the body mount support bracket are secured to the frame portion, such as by welding, adhesives, and the like. The flexing of the leg portions is performed to create internal stresses within the body mount support bracket that remain after the body mount support bracket has been secured to the frame assembly. These residual internal stresses are effective to increase the strength and rigidity of the body mount support bracket beyond what would normally be obtained if the body mount support bracket was secured to the frame assembly side rail in an unstressed condition.

  • Patent number: 7310993
    Abstract: Sensor apparatus for a multiple layer steel (MLS) cylinder head gasket measures combustion pressures for detecting engine conditions. A membrane is positioned at one end of an elongated metal tube, and the membrane end of the tube engages a cylinder bore boundary. A fiber optical sensor apparatus is fixed within the tube, and communicates with cyclic combustion events via the membrane. In one disclosed embodiment, optical wires from sensor apparatus situated at each engine bore are bundled into a common groove machined into an extended spacer layer radially outwardly of the conventional boundary of the gasket. The tube protects the sensor apparatus from damage of sealing stress on the gasket, and particularly at the bore perimeter. Each tube lies in a separate groove in the spacer layer that terminates at the bore boundary. A converter changes optical signals received from the apparatus into electrical signals for transmittal to a controller.

  • Patent number: 7293779
    Abstract: A gasket includes an intermediate layer having resilient sealing beads flanked by stopper beads. The three-layer gasket, particularly designed for heavy duty racing engines, provides a relatively robust cross-section in web-areas between cylinder bore apertures. A thin bottom layer includes wrap-around flanged portions extending about cylinder bore edges of the intermediate layer to partially overlap cylinder bore aperture areas of that layer. The flanged portions may include a plurality of waves to increase forces to generate the seal. A thin top layer overlies the intermediate layer, as well as the overlapping portions of the bottom layer. In one described embodiment, the overlapping portions are limited to cylinder bore edges between cylinder bores. As a between-engine-overhaul indication of engine health, the top gasket layer is adapted via plastic deformation to form a permanent indentation in an aluminum cylinder head to signal excessive engine operation.
