High-pressure hydrogen vehicle tank seal
PATENTS
Mechanical seal with compact external quench supply
High-pressure hydrogen vehicle tank seal
Applicant: Eagle Industry Co Ltd, Japan This patent describes a mechanical seal which is designed to have an external quench supply within compact dimensions and also be readily assembled and disassembled. The quench is provided through port (40) and circulates around the outside diameter of the seal faces (3, 10) and into the narrow space on the periphery of the static seal ring (30F). The leakage of quench fluid is prevented by a packing ring (4). Although not specifically mentioned in the English abstract, this seal appears to have the sealed product on the inside diameter. Patent number: WO 2006/022378 Inventor: H. Takahashi Publication date: 2 March 2006
Applicant: Quantum Fuel Systems Technologies Worldwide Inc, USA This seal system is for high pressure storage tanks such as those that may be used for containing hydrogen on hydrogen powered vehicles. The storage pressure may be up to 700 bar. The seal system includes a radial valve body that is fitted within a circular spring energizer, which are then both
Stainless steel sheet for gaskets
The compact mechanical seal with quench flow to the outside diameter of the seal, as described in WO 2006/022378.
Joint for engine exhaust system component Applicant: Donaldson Company Inc, USA This patent describes an improved jointing between an exhaust pipe and the various components that may require changing or servicing such as catalytic converter, diesel particulate filter or NOx trap.
fitted within a boss. The spring energizer and the boss are separated by a non-bonded liner. Various radial seals are placed within the inner surface of the boss member to ensure the seal, and the seal system is installable to the top portion of a liner of a storage tank. Patent number: WO 2006/034439 Inventors: J. Van Oyen et al. Publication date: 30 March 2006
Flanged ends of the components and the matching pipe have flanged sections that are secured by a V-clamp. Patent number: WO 2006/029199 Inventors: J.I. Belisle and J.T. Hansmann Publication date: 16 March 2006
Applicants: Sumitomo Metal Industries Ltd and Honda Motor Co, Japan A high-strength, high-performance stainless steel sheet designed as a gasket for high performance engines of automobiles or motorcycles is described. It has excellent machinability and fatigue characteristics. In the region within a minimum of 3 µm from the sheet surface there are nitride compounds with a size of
10–200 nm in a concentration of 200 or more per 100 µm2. Alternatively, the number of nitride compounds having a size of 10–200 nm in the region within 3 µm from the sheet surface is not less than twice as many as the number of nitride compounds of the same size in the center of the sheet. Patent number: WO 2006/035667 Inventors: K. Adachi et al. Publication date: 6 April 2006
Cast-iron pipe joint seal for socket type pipe joint Applicant: Saint-Gobain Pam, France This patent describes a pipe joint seal that is intended to provide improved retention in a socket type pipe joint. The pipe joint housing end piece (8) has an anchoring groove (82), into which is fitted a plastic ring (14)
which contains several locking inserts (20). Each locking insert comprises a head (30) to butt up against the radial face of the groove and serrations on the inside diameter. Patent number: WO 2006/035141 Inventors: A. Percebois et al. Publication date: 6 April 2006
Detailed section of the V-clamp and mating flanges for the exhaust component joining system, from WO 2006/029199.
Boot for constant velocity joint Applicants: NTN Corporation, Japan A boot for a constant velocity joint that features reduced weight, is compact, and is suitable for high-speed rotation is described. The boot is formed of
