| 20080204714 | ON-VEHICLE FUEL PROPERTY DETECTION DEVICE - The detection device provides with an optical fiber composed of a core, a clad and a fiber jacket. A grating is applied to the core, and the fiber jacket located at the portion to which the grating is applied is removed so that the clad is in contact with a fuel fed to an injector of a vehicle. The detection device also provides with a light source for incidence of a light in a range of clad mode wavelength to the optical fiber, and a light-sensitive part for detecting an intensity of the light transmitting through the region to which the grating is applied. The optical fiber, light source and light-sensitive part are held in a conduit disposed in a fuel tank or between a fuel pump and the injector of the vehicle. | 08-28-2008 |
| 20080216801 | FUEL SUPPLY SYSTEM - A fuel supply system provided in a fuel tank includes: a fuel pump that sucks fuel reserved within the fuel tank via a suction filter and discharges the sucked fuel; a pressure regulator that maintains pressure of the fuel discharged from the fuel pump within a predetermined range; a pump holder that holds the fuel pump and the pressure regulator; and a cushioning rubber extending in radial and axial directions of the fuel pump between the pump holder and the fuel pump for damping vibrations associated with driving of the fuel pump. Excess fuel is introduced in a flow path from the pressure regulator to the suction filter. The flow path includes: a gap defined between the pump holder and the cushioning rubber; and a gap defined between the cushioning rubber and the fuel pump. | 09-11-2008 |
| 20080216904 | FUEL SUPPLY SYSTEM - A fuel supply system includes: a flange mounted at an upper opening in a fuel tank; a fuel pump that discharges fuel in the fuel tank; a high-pressure filter that filters fuel discharged from the fuel pump; and a filter case that accommodates the high-pressure filter and includes an upper case and a lower case, the upper case integrally formed with the flange. The fuel pump is fitted to an underside of the lower case to be positioned substantially coaxial with the high-pressure filter. | 09-11-2008 |
| 20090034901 | OPTICAL FIBER SENSOR - An optical fiber sensor that can detect a liquid level or detect a property of liquid with high reliability even under a frequently vibrational environment. The optical fiber sensor includes an optical fiber that includes a core having an area where a grating is formed and a clad, and is disposed so that at least a part of the area with the grating is immersed in liquid, a light source for making light incident to the optical fiber so that a cladding mode light having a wavelength band is occurred by the grating, and a light receiving unit for detecting the intensity of light which is incident from the light source to the optical fiber and transmitted through the grating. | 02-05-2009 |
| 20110043799 | OPTICAL FIBER SENSOR AND FUEL SUPPLY APPARATUS HAVING THE SAME - An optical fiber sensor includes: an optical fiber; a light source portion; and a light receiving portion. The optical fiber includes: a core that includes a grating that generates a clad mode upon receipt of light; a clad that covers the core; and a fiber jacket that covers the clad, wherein a part of the fiber jacket corresponding to an area where the grating is formed is removed so that the lad is contactable with the fuel. The light source portion includes a light cutting element that emits light, whose wavelength is within a wavelength band of the cladding mode toward the optical fiber. The light receiving portion that detects intensity of the light transmitted through the grating. The optical fiber, the light receiving portion and the light source portion are arranged linearly. | 02-24-2011 |
