Patent number: 9539894Abstract: A fuel tank includes a tank body having an outer wall formed of a synthetic resin layer having a multilayer structure. The tank body has at least an inner body layer (an inner adhesive layer and an inner base layer) and an outer body layer (a skin layer, an outer base layer, and an outer adhesive layer) between which a barrier layer is interposed. A structure having an air layer therein is attached to the outer side of the skin layer of the outer body layer.Type: GrantFiled: June 9, 2015Date of Patent: January 10, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Kotaro Tanaka, Shoichiro Kumagai, Hiroshi Kitamura

Patent number: 7647955Abstract: In a filler pipe assembly, a holder member secured to an inner wall of a filler pipe is provided with an outer profile of a circular cross section substantially conforming to an inner peripheral wall of the filler pipe and an inner profile defining a bore of a circular cross section eccentric to the outer profile thereof. A relief valve is provided in a part of the holder member defined between the outer profile thereof and the bore owing to an eccentricity of the bore relative to the outer profile. Owing to the eccentric relationship between the outer profile and inner bore of the holder member, a space for a relief valve can be provided in the area where the distance between the inner wall of the bore and the outer profile is the greatest, and this allows the relief valve to be mounted without complicating the structure.Type: GrantFiled: January 29, 2007Date of Patent: January 19, 2010Assignee: Honda Motor Co., Ltd.Inventors: Shinya Murabayashi, Shoichiro Kumagai, Tsuyoshi Chou, Nobuyuki Kosaka, Keiichiro Tachisako

Patent number: 7615108Abstract: A canister includes a casing made of a material including a polyamide resin. The casing includes a charge port to let in fuel vapor, a purge port to let out desorbed fuel and an atmospheric air port to let in air. Granular adsorbing agent and granular heat storing agent are held in the casing. The adsorbing agent includes a granular activated carbon. The granular heat storing agent is mixed with the granular activated carbon in the casing, and the granular heat storing agent including the material of the casing.Type: GrantFiled: September 26, 2007Date of Patent: November 10, 2009Assignees: Mahle Filter Systems Japan Corp., Honda Motor Co., Ltd.Inventors: Hiroyuki Yoshida, Koji Yamazaki, Koichi Hidano, Shoichiro Kumagai, Takahiro Imamura

Publication number: 20090000669Abstract: A fuel cutoff valve 10 has a float assembly 52 and an upper valve plug 60 located in a valve chest 30S defined by a casing 20. The float assembly 52 has a valve support member 55 formed in its upper portion to support the upper valve plug 60. The upper valve plug 60 has a support convex 66b held on a support plane 56a of the valve support member 55, where a center of gravity of the upper valve plug 60 is located below a supporting point 55a around which the support convex 66b is balanced on the valve support member 55. The upper valve plug 60 includes a first valve section 61 and a second valve section 65. The first valve section 61 has a first valve body 62 and a sheet member 64. The first valve body 62 is made of POM (polyoxymethylene), while the second valve section 65 is made of PA6 (polyamide) containing 30% of glass fibers. The second valve section 65 is accordingly structured to have a lower density than the first valve body 62.Type: ApplicationFiled: June 26, 2008Publication date: January 1, 2009Applicants: TOYODA GOSEI CO., LTD., HONDA R&D CO., LTD.Inventors: Hiroaki Kito, Kenichiro Kaneko, Hiroshi Nishi, Shoichiro Kumagai, Hiroshi Kitamura, Yasuhiro Hasegawa, Shoji Uhara

Publication number: 20070210607Abstract: In a filler pipe assembly, a holder member (13. 15) secured to an inner wall of a filler pipe (2) is provided with an outer profile of a circular cross section substantially conforming to an inner peripheral wall of the filler pipe and an inner profile defining a bore (17) of a circular cross section eccentric to the outer profile thereof. A relief valve (30) is provided in a part of the holder member defined between the outer profile thereof and the bore owing to an eccentricity of the bore relative to the outer profile. Owing to the eccentric relationship between the outer profile and inner bore of the holder member, a space for a relief valve can be provided in the area where the distance between the inner wall of the bore and the outer profile is the greatest, and this allows the relief valve to be mounted without complicating the structure.Type: ApplicationFiled: January 29, 2007Publication date: September 13, 2007Applicant: Honda Motor Co., Ltd.Inventors: Shinya Murabayashi, Shoichiro Kumagai, Tsuyoshi Chou, Nobuyuki Kosaka, Keiichiro Tachisako
