Patent number: 8875565Abstract: This device includes an outer casing having: a first tubular zone (16) to the inside of which a finger (4) is fastened; a second tubular zone (40) of larger outside diameter than that of the first tubular zone (16) and extending the first tubular zone (16); and an elastically deformable part (18) of annular shape, extending in a plane transverse to the first tubular zone (16) and connecting the first tubular zone (16) to the second tubular zone (40). The pressure sensor (8) is placed between, on one side, an element (30) integral with the finger and, on the other side, a fixed element (20), called an interface, which is integral with the second tubular zone (40). The interface (20) has an axial contact zone (42) for contact with an element constituting the second tubular zone.Type: GrantFiled: September 4, 2009Date of Patent: November 4, 2014Assignees: Continental Automotive France, Federal-Mogul Italy SRLInventors: Alain Ramond, John Burrows, Sandro Goretti

Patent number: 8356511Abstract: A device includes a pressure sensor (11-13) for measuring pressures inside the combustion chamber of a cylinder in an internal combustion engine. The device includes: an outer body (1); a lug (5) extending partially into the combustion chamber; an inner housing (14) inserted into the body and surrounding an upper portion of the lug, the housing being secured to the lug and to the body and having an elastically deformable portion (17) between the two securing areas, characterized in that the housing (14) is secured to the body (1) at a securing area (18) extending in the upper portion of the body.Type: GrantFiled: September 4, 2009Date of Patent: January 22, 2013Assignees: Continental Automotive France, Federal-Mogul Italy SrlInventors: Alain Ramond, Sandro Goretti, John Burrows

Patent number: 8319153Abstract: A glow plug assembly (110) has a metallic heater probe (118) supported within a metal shell (112). A transition zone (144) at the base of the shell (112) includes a membrane (146) and a tube portion (148). A first open end (130) of the heater probe (118) is formed with a reduced diameter pilot section (150) that mates with the tube portion (148) to establish a joint area between the components. The membrane (146) may be made elastically deflectable so as to accommodate integration of a pressure sensor (156) in the glow plug assembly (110).Type: GrantFiled: November 17, 2008Date of Patent: November 27, 2012Assignee: Federal-Mogul Italy Srl.Inventors: John A Burrows, Marcello Cino, Sandro Goretti

Patent number: 8217309Abstract: A glow plug assembly includes an integrated, internal pressure sensor. In order to reduce loading on the center electrode, improve sensor responsiveness, and provide better thermal performance, the pressure sensor assembly is housed in a canister which forms a containment capsule and rigidly connects inside the glow plug shell near its seat area. The pressure sensor makes direct contact with the base end of the heater probe so that movements of the heater probe caused by fluctuations in gas pressure lead directly to changing force on the sensor stack.Type: GrantFiled: December 15, 2008Date of Patent: July 10, 2012Assignee: Federal-Mogul Italy Srl.Inventors: John A. Burrows, Sandro Goretti

Publication number: 20110192358Abstract: A device for measuring pressures inside an internal combustion engine, includes an outer housing having: a first tubular area (16) in which a lug (4) is received and a second tubular area (40) having an outer diameter larger than that of the first tubular area (16), the second tubular area (40) including an element (12) for securing the same in a bore as well as a conical bearing surface (36). The conical bearing surface (36) is formed at the end of an annular skirt (38) defining an extension of the second tubular area (40) and surrounding the first tubular area (16) while leaving a free gap (44) between the skirt (38) and the first tubular area (16).Type: ApplicationFiled: September 4, 2009Publication date: August 11, 2011Applicants: CONTINENTAL AUTOMOTIVE FRANCE, FEDERAL-MOGUL ITALY SRLInventors: Alain Ramond, John Burrows, Sandro Goretti
