Patent number: 8013502Abstract: A spark plug (10) includes an intermediate connecting pin (54) disposed in the central passage (28) of an the insulator body (12). The connecting pin (54) seats in an intermediate taper section (72) within the central passage (28), which is generally frustoconical and establishes a transition between a first larger diameter of the central passage (28) and a second smaller diameter. The intermediate tapered section (72) is located longitudinally above a filleted transition (26) feature of the insulator body (12) exterior. A pin head (53) of the connecting pin (54) has a complementary tapered under-cut and seats against the intermediate tapered section (72) to provide self-centering of the connecting pin (54) without trapping gas during the assembly process. The intermediate taper section (72) also provides an increase in insulator wall thickness which improves dielectric capacity and structural integrity of the insulator (12).Type: GrantFiled: May 16, 2008Date of Patent: September 6, 2011Assignee: Federal-Mogul CorporationInventor: John W.

Publication number: 20110168138Abstract: A system for supplying fuel under pressure to an internal combustion engine, and to control fuel delivery to a fuel injection system in an internal combustion engine having a low pressure pump formed integrally as at least part of a main housing of a vapor separator assembly. The low pressure pump lifts fuel into a cavity of a reservoir, which is drawn from a high pressure pump into the internal combustion engine. Due to the integrated nature of the low pressure pump, leak paths and assembly costs are reduced.Type: ApplicationFiled: January 7, 2011Publication date: July 14, 2011Applicant: FEDERAL-MOGUL CORPORATIONInventor: Kyle Dean Achor

Patent number: 7959840Abstract: A method of constructing a shaft seal assembly includes attaching a PTFE seal element to an outer metal case and disposing a bore of the PTFE seal element onto a mandrel. Then, heating the PTFE seal element while on the mandrel. Further, cooling the PTFE seal element while on the mandrel and, removing the shaft seal assembly from the mandrel. The resulting seal element provides a reliable seal against a running surface of a shaft in use, while at the same time producing low running torque against the running surface of the shaft. Further, a minimal axial push force is required to install the shaft seal assembly onto the shaft, thereby reducing the potential of damage to the seal element or inversion of the seal element during installation.Type: GrantFiled: June 11, 2009Date of Patent: June 14, 2011Assignee: Federal Mogul CorporationInventor: Frederick R. Hatch

Publication number: 20110135381Abstract: A replacement ball joint assembly (10) adapted to be pressed into a previously used and possibly distorted receiving hole (26) in a suspension component such as a control arm (28). A socket housing (12) of the assembly (10) includes a plurality of generally annular, concentric knurls (36) each having a respective crest portion (38) and separated one from another by intervening relief grooves (40). The crest portions (38) of the knurls (36) may be tapered so as to provide a lead-in feature to minimize misalignment during a press-in installation operation. The knurls (36) are preferably softer than the control arm material so that they yield during press-in rather than further disfiguring or enlarging the receiving hole (26). Displaced material from the crest portions (38) of the knurls (36) flows into the relief grooves (40).Type: ApplicationFiled: December 3, 2009Publication date: June 9, 2011Applicant: FEDERAL-MOGUL CORPORATIONInventors: Michael Wilcutt, George Phillips, Anthony Dake, Rickie Williams, Chris Shores, Kennon Bret Swayer
