Seal structure for fuel injection valve
PATENTS
Pressure relief valve embedded in molded rubber seal to prevent overpressurization Applicant: Schrader-Bridgeport International Inc, USA This patent application relates to pneumatic tires, and specifically to the inclusion of a pressure-limiting relief valve to actively limit the pressure in the tire. The invention is characterized in that the seal (122) is restrained by the spring (126), and will allow the
tire to vent if it exceeds a preset pressure. The patent describes how the pressure adjusting nut is held in place through the use of an anaerobic sealant to prevent tampering. Patent number: WO 2005/082647 Inventor: J.A. Schultz Publication date: 9 September 2005
Pneumatic tire valve that also permits venting in the event of excess pressure, from WO 2005/082647.
Extremely thin, cold rolled steel sheet for gasket Applicant: Toyo Kohan Co, Japan This patent describes an extremely thin cold rolled steel sheet with high strength, as well as a method for manufacturing the sheet. It has the chemical composition C (0.03–0.20 wt%), Si (<0.5 wt%), Mn (0.5–3.0 wt%), P (<0.1 wt%), S (0.06 wt%), Al (0.1 wt%), N (0.0010–0.0160 wt%) and the balance of Fe. The
extremely thin sheet exhibits high strength and workability and spring characteristics, and it can be produced at low cost. The spring characteristics make it suitable for sealing cooling water and lubricating oil passages. Patent number: WO 2005/083140 Inventors: S. Aoki et al. Publication date: 9 September 2005
Seal structure for fuel injection valve Applicant: Bosch Corporation, Japan An alternative seal is described in this patent application that is designed for application to a fuel injection valve. The seal (31) is supported by a rigid backup ring (32). The design is characterized in that a series of claws (33) on the backup ring locate the seal and prevent it from being displaced. (See also Seal for fuel injection valve with improved location on page 16.) Patent number: WO 2005/085629 Inventor: H. Kawasumi Publication date: 15 September 2005
High-pressure seal for a fuel injection valve that uses a series of claws (33) to locate the seal, from WO 2005/ 085629.
Swimwear with resilient silicone seal Applicant: Nike Inc, USA This patent describes a resilient seal for the apertures of a swimsuit to improve the fit and avoid drag. A silicone seal is preferred as it is dimensionally stable in water and will not stretch when wet, thereby ensuring a tight seal on the user’s
14
body. A range of swimwear, from full body suits to the briefest trunks, are described in this patent application. Patent number: WO 2005/087028 Inventor: M.D. Nordstrom Publication date: 22 September 2005
Seal assembly for fluid components Applicant: Swagelok Co, USA This invention relates to a seal that includes a seal structure and a holding plate structure. The seal structure and the holding plate structure are preferably formed together for assembly between two fluid components. It is specifically intended to provide a single component seal for use in manifold blocks, and other components with multiple fluid ports. The seal structure includes at least three abutting layers of metal, including first and second outer layers for engagement with the first and second fluid components and an inner layer, the first and second outer layers having a hardness that is selected to be less than the hardness of the counter-bores of the first and second components, and with the inner layer having a hardness that is selected to be greater than the hardness of the first and second outer layers. The inner layer of the seal structure transmits force between the outer layers when the components are joined
together with the seal structure in the counter-bores. Patent number: WO 2005/085685 Inventors: M.A. Bennett et al. Publication date: 15 September 2005

Peelable seal closure assembly for medical solutions Applicants: Baxter International Inc, USA and Baxter Healthcare SA, Switzerland This invention provides a peelable seal for a multi-chambered container. Multiple chamber containers having sub-chambers separated by a peel seal, frangible seal or other fluid connecting device are widely used to separately store two or more components, which are mixed inside the container prior to
administering the mixed solution to a patient. The components can be in a powder or liquid form, and are typically mixed together to form a therapeutic solution. At least one of the edges includes a stress-bearing portion and a nonstress-bearing portion. Patent number: WO 2005/084607 Inventors: V. Houwaert et al. Publication date: 15 September 2005
Fuel cell gasket with an integrated sensor Applicant: Freudenberg-NOK GP, USA This patent covers a gasket with an integrated sensor, in which the gasket has a sensor formed on a protruding portion of it. The purpose is to monitor fuel cell parameters such as hydrogen flow, cell voltage etc., and hence provide a condition monitoring facility. Patent number: WO 2005/086263 Inventor: M. Belchuk Publication date: 15 September 2005
Fuel cell gasket with integrated sensor for condition monitoring of a fuel cell’s output, from WO 2005/086263.
