Patent number: 10746332Abstract: A ball and socket coupling that avoids threaded tightening-components instead has telescoped components that are bonded together. Such a coupling has a hollow seat-formed link, a counterpart hollow ball-formed link, and a socket-forming collar. Both the links have fitting extensions. The ball-formed link has a spherical bulb at one end as the seat-formed link has a conforming, spherically-widening seat surface at one end. The socket-forming collar has a centrally apertured web with a conforming spherically-narrowing socket surface at one end of an axially elongated sleeve. The coupling is adapted to be assembled and bonded into solid rigidity by workers in the field with the spherical bulb bonded to and clamped between the seat-formed link's spherically-widening seat surface and the collar's spherically-narrowing socket surface. In addition, the collar's elongated sleeve is bonded internally to the seat-an outer sidewall of the seat-formed link's seat-formed end.Type: GrantFiled: September 7, 2017Date of Patent: August 18, 2020Inventor: Roger C.

Publication number: 20040163617Abstract: An electronic system generally includes a flatwire electronic site and a flatwire bus electronically connecting the flatwire electronic site and an electronic device in the engine compartment. The flatwire electronic site has a flexible substrate with electronic components attached to the substrate for operation of the electronic device. The flatwire electronic site is mounted to the engine side of the bulkhead for thermal cooling of the flatwire electronic site. A cover is attached to the bulkhead which encloses a flatwire electronic site for environmental protection.Type: ApplicationFiled: February 21, 2003Publication date: August 26, 2004Applicant: Visteon Global Technologies, Inc.Inventors: Andrew Glovatsky, Myron Lemecha, Lawrence Kneisel, Brenda Nation

Patent number: 4909202Abstract: A valve stem seal assembly includes a rigid cylindrical shell and an annular resilient seal body contained entirely within the shell. Integral to the seal body is a frustoconical sealing element adapted to engage a valve guide of an internal combustion engine. The sealing element converges radially inwardly, and upon installation of the assembly on a valve guide the outer surface of the sealing element bends further radially inwardly to effectively seal the top surface of the guide. The seal body includes a stem sealing aperture, which in one preferred embodiment is designed to engage the valve stem without a spring. In a same or similar embodiment, the shell contains a circumferential array of tangs for retention of the assembly on the guide.Type: GrantFiled: June 30, 1989Date of Patent: March 20, 1990Assignee: Dana CorporationInventors: J. Dudley Binford, Philip L. Bond, David F. Fiedler, Ivan J. Bruns

Patent number: 4341185Abstract: A valve housing for an internal combustion engine having more than one intake or exhaust valve per cylinder includes complementary upper 14 and lower 16 members, with a transverse junction plane 17 intersecting a longitudinal partition 10 which divides an annular cavity 9 between a central valve bushing and a circumferential wall of the housing into separate coolant supply and return sections 9a and 9b, respectively. An intermediate element 17 is interposed between said members and is provided with openings 19, 20 smaller angular extents than the corresponding coolant sections to provide for proper circulation of coolant between the portions of a given section (9a or 9b) of cavity 9 while permitting different angular relations between said members.Type: GrantFiled: December 4, 1979Date of Patent: July 27, 1982Assignee: Societe d'Etudes de Machines Thermiques S.E.M.T.Inventor: Jean-Pierre Pollet

Patent number: 4182282Abstract: The invention provides a mushroom valve housing comprising a cage (1) and a guide (2), Cage (1) comprises legs (3, 4, 5, 6) supporting a valve seat (7) containing an annular space (8). Guide (2) has an annular cavity (9) with two sections (9a, 9b) communicating with space (8) by passages (11 to 14). One passage (12) among the two passages (11, 12) connected to a same section (9b) freely opens into this section whereas the other passage (11) communicates directly with the other section (9a), the passages (11, 13) of two diametrically opposite legs (3, 5) communicating with a same section (9a).Type: GrantFiled: May 19, 1978Date of Patent: January 8, 1980Assignee: Societe d'Etudes de Machines Thermiques S.E.M.T.Inventor: Jean-Pierre Pollet
