20090095265 | FUEL SUPPLY DEVICE - A fuel supply device supplies fuel contained in a fuel tank to a combustion engine. The fuel supply device comprises an upper unit which is fixed to an installation hole formed on an upper surface of the fuel tank, a lower unit placed inside the fuel tank, a fuel pump mounted to either the upper unit or the lower unit, and a control module for controlling operation of the fuel pump. The control module is disposed inside the fuel tank. A part of the upper unit is located on one side of the control module in a horizontal direction. A part of the lower unit is located on the other side of the control module in the horizontal direction. In this structure, the control module disposed inside the fuel tank can be protected against swaying fuel. | 04-16-2009 |
20090151699 | FUEL-FEEDING DEVICES - A fuel-feeding device may preferably include a reservoir cup disposed in a fuel tank that contains liquid fuel therein, a fuel pump capable of feeding the liquid fuel contained in the reservoir cup to an engine, a pressure regulator capable of controlling a fuel pressure of the liquid fuel fed to the engine from the fuel pump, a jet pump arranged and constructed to receive a part of the pressurized liquid fuel pumped from the fuel pump via a fuel jet path, so as to introduce liquid fuel outside the reservoir cup into to the reservoir cup with the aid of flow of the pressurized liquid fuel, and a flow rate control valve disposed in the fuel jet path. The flow rate control valve is arranged and constructed to control a flow rate of the pressurized liquid fuel fed to the jet pump depending upon a pumping rate of the pressurized liquid fuel pumped from the fuel pump. | 06-18-2009 |
20100175666 | FUEL SUPPLY SYSTEMS - On aspect according to the present invention includes a fuel supply system including a backflow preventing device provided in a fuel supply path communicating between a fuel pump and a fuel injecting valve device of an engine. The backflow preventing device can prevent backflow of the fuel from the fuel injecting valve device, so that a pressure of the fuel between the backflow preventing device and the fuel injecting valve device can maintained after stopping the fuel pump. | 07-15-2010 |
20110192786 | FUEL FILTER - A fuel filter for filtering engine fuel received in a fuel tank when the engine fuel is fed to an engine may include a filter member that is received in the fuel tank and is capable of being connected to a fuel inlet port through which the engine fuel is drawn, and a wall member that is connected to a circumferential periphery of the filter member to form a container member. The wall member and the filter member are respectively arranged and constructed to function as a side portion and a bottom portion of the container member. The filter member is capable of being disposed in the fuel tank so as to draw the engine fuel received in the fuel tank through a side thereof that faces the bottom wall of the fuel tank. | 08-11-2011 |
20110297126 | FLUID PRESSURE REGULATING DEVICE AND FUEL SUPPLY SYSTEM USING SAME - A fluid pressure regulating device is i) provided with a pressure regulating member that forms a pressure regulating chamber inside a housing having introduction side and discharge side fuel passages, and communicates these passages according to introduced fuel pressure, and ii) is able to regulate the fuel pressure introduced into a fuel passage to a set pressure. The housing is provided with outer and inner annular valve seat portions that separate the fuel passages inside the pressure regulating chamber, and form another fuel passage inside the pressure regulating chamber. Different clearances are set between the pressure regulating member, and the outer annular valve seat portion and the inner annular valve seat portion, such that when the pressure regulating member abuts against one of the valve seat portions, a small gap is formed between the other valve seat portion and the pressure regulating member. | 12-08-2011 |
20130032126 | FUEL SUPPLY APPARATUS - The fuel supplied apparatus disclosed is capable of optimizing the timing of performing the fuel pressure change indication and the fuel injection timing to suppress the real fuel injection amount from being differentiated from the target fuel injection amount even at the time of the fuel pressure being changed, thereby making it possible to accomplish the improvement of the fuel consumption. The ECU judges whether or not the fuel pressure change request is generated (Step S | 02-07-2013 |
20140042079 | FUEL FILTRATION DEVICES - A fuel filtration device may include a filter element and a space-keeping member. The filter element may have a plurality of fusion-bonded portions and have a space defined therein. The space-keeping member may have crosspieces defining openings therebetween and may face a surface of the filter element in a facing direction. The fusion-bonded portions may include those that do not overlap with the crosspieces of the space-keeping member in the facing direction. | 02-13-2014 |
20140096849 | FUEL SUPPLY DEVICE - A fuel supply device is obtained in which joint strength can be maintained in a joint portion of plural filter members configuring a fuel filter. A fuel filter ( | 04-10-2014 |
