Patent number: 7500473Abstract: A vehicle fuel supply device including a saddle-shaped fuel tank comprised of a main chamber and an auxiliary chamber. A reservoir is disposed within the main chamber. A main pump is provided within the reservoir. A sub-pump is detachably provided within the reservoir. The fuel in the reservoir is drawn up by an operation of the main pump to supply fuel to an engine. A portion of the drawn-up fuel is utilized to generate a negative pressure, the negative pressure is utilized to transfer the fuel in the auxiliary chamber to the reservoir, and the negative pressure is utilized to introduce the fuel in the main chamber into the reservoir.Type: GrantFiled: March 26, 2008Date of Patent: March 10, 2009Assignee: Honda Motor Co., Ltd.Inventors: Kazuhiro Kobayashi, Takeaki Nakajima, Shoichi Hokazono, Shinya Murabayashi, Hideharu Yamazaki, Kenji Hirose, Takeshi Kumakura, Shukoh Terata

Patent number: 7497208Abstract: A fuel supply device mounted on an automotive vehicle includes a fuel pump and a sub-tank containing the fuel pump therein. The sub-tank and the fuel pump are submerged in fuel contained in a fuel tank. Operation of the fuel pump is controlled in a switching manner thereby to supply the fuel contained in the fuel tank to an internal combustion engine. When the fuel tank is made of a resin material, electromagnetic noises generated in the switching operation of the fuel pump are emitted from the fuel pump through the fuel tank, interfering with radio waves received by a receiver mounted on an automotive vehicle. To shield such noises, the fuel pump is disposed in the sub-tank that is made of a metallic material and grounded to a body of the vehicle. In this manner, the noises from the fuel pump are surely intercepted.Type: GrantFiled: April 24, 2007Date of Patent: March 3, 2009Assignee: DENSO CORPORATIONInventors: Taketoshi Satoh, Manabu Nomura

Publication number: 20090044783Abstract: The invention relates to a fuel pump for a fuel system of an internal combustion engine, having a housing and a housing cap joined to the housing. In order to create a fuel pump which in its operation generates little airborne sound, structure-borne sound (vibration amplitudes) and pulsations in a low-pressure region of the fuel pump, it is proposed that the housing cap has at least one damping element, which is embodied as a sandwich construction having at least a first cover layer, a second cover layer, and a damping connection layer disposed between them. The damping connection layer has a markedly higher elasticity and/or higher material damping than the two cover layers, which may be constructed of sheet metal or the housing cap itself.Type: ApplicationFiled: August 6, 2008Publication date: February 19, 2009Inventors: Michael Fischer, Matthias Schumacher, Christian Wiedmann, Matthias Maess, Matthias Fischer

Publication number: 20090025690Abstract: A fuel supply device includes a subtank in a fuel tank, a fuel pump in the subtank having a first pump unit suctioning fuel in the subtank to supply fuel to an external equipment and a second pump unit suctioning fuel outside the subtank to pump fuel into the subtank, and a filter connected to a first suction port of the first unit and a second suction port of the second unit and filtering supply fuel supplied to the equipment and pump fuel pumped into the subtank. The filter includes a case, a first filter, and a second filter. The first filter in a first passage of the case directing fuel in the subtank into the first port filters the supply fuel. The second filter in a second passage of the case directing fuel outside the subtank into the second port filters the pump fuel.Type: ApplicationFiled: July 23, 2008Publication date: January 29, 2009Applicant: DENSO CORPORATIONInventors: Katsuhisa YAMADA, Masaaki TANAKA, Chiaki KAWAJIRI
