Patent number: 10119614Abstract: A multi-layer gasket including first and second functional layers, each having an opening. Each of the functional layers includes a compression bead, and the compression beads contact and seal against one another when the gasket is compressed between a cylinder head and an engine block. At least one of the functional layers includes a stopper disposed between the compression bead and the opening. The stopper has a gear-like shape including a plurality of circumferentially spaced teeth. Each tooth extends upwardly from a plane by a distance which is less than the combined height of the compression beads. When the gasket is compressed between the cylinder head and engine block, the stopper ensures that the compression beads remain elastically biased against one another and maintain a gas-tight seal.Type: GrantFiled: May 11, 2015Date of Patent: November 6, 2018Assignee: Tenneco Inc.Inventors: Edward Lesnau, IV, Jim Zwick, Marcin Fracz

Patent number: 9970548Abstract: A multi-layer gasket for establishing a seal between a first member (such as a cylinder head) and a second member (such as an engine block) is provided. The multi-layer gasket includes a pair of outer functional layers and at least one inner functional layer. Each layer has a full combustion bead that encircles an opening, and the full combustion beads of all of the layers are aligned radially with one another. Each layer also has an outer periphery, and the outer periphery of the inner layer is disposed radially between the aligned full combustion beads and the outer peripheries of the outer layers.

Patent number: 8752841Abstract: A cylinder head gasket has a functional layer with a plurality of openings with a compression bead surrounding at least one of the openings. The functional layer additionally includes a plurality of stoppers, or compression limiters, spaced from the compression bead for preventing full flattening of the compression bead between the engine block and the cylinder head and for limiting the expansion and contraction of the compression bead during and between firings in the cylinders of the engine block. At least one of the stoppers has a generally frustoconical shape with a top and a reverse-frustoconical opening in the top.Type: GrantFiled: May 18, 2012Date of Patent: June 17, 2014Assignee: Federal-Mogul CorporationInventors: Michael Davidson, Edward Lesnau, IV, Chris LaFrenz

Patent number: 8616557Abstract: A multilayer metal gasket (40) having first (28) and second (30) functional layers. Each layer (28, 30) includes an opening (34, 38). Sealing beads (42, 44) are formed in each layer (28, 30) and, preferably, arranged to contact each other in crest-to-crest orientation to perfect a seal therebetween. A stopper feature (54) is provided to restrict compression of the sealing beads (42, 44) in use. The stopper feature (54) is arranged in a generally circular pattern and is composed of a plurality of discrete nesting embossments (56) which are closely spaced to one another but do not touch. Each discrete nesting embossment (56) is substantially identical in shape to the next adjacent discrete nesting embossment (56) but oriented approximately 180 degrees therefrom. The embossments (56) may be formed entirely on one of the functional layers (28, 30) or on both functional layers.Type: GrantFiled: October 6, 2011Date of Patent: December 31, 2013Assignee: Federal-Mogul CorporationInventors: Christopher J Lafrenz, Edward Lesnau, IV

Patent number: 8375800Abstract: A compression sensor gasket and method of construction thereof is provided. The gasket has a body with opposite sealing surfaces and a through passage configured to align with a chamber to be sealed. A through opening extends between the sealing surfaces to the through passage and has an annular chamfered surface. A pressure sensor assembly having a housing and a pressure sensor extending at least partially through the housing is disposed in the through opening. The pressure sensor has a pressure sensor tip configured to sense pressure within the chamber to be sealed. The housing has an outer annular tapered surface configured to register in radial alignment with the chamfered surface to facilitate forming a hermetic seal between the pressure sensor assembly and the gasket body.Type: GrantFiled: October 2, 2009Date of Patent: February 19, 2013Assignee: Federal-Mogul CorporationInventors: Edward Lesnau, IV, James R.
