Abstract: PROBLEM TO BE SOLVED: To attach a liquid-level detector to a fuel tank as a unitary body with a fuel supply pump without attaching work such as screw tightening. SOLUTION: In this attaching structure, a protruding member 4, a holding piece 8 for holding an attaching surface 3a and a plurality of pawls 10a are provided as the first engaging means at a body 5 of a liquid-level detector, and a groove 6 and receiving parts 10b are provided as the second engaging means at the attaching surface 3a of an attaching member 3. Furthermore, the thickness of the protruding member 4 in the direction of the groove 6 is set so that the width is equal to or slightly larger than the width of the groove 6. The interval between the holding piece 8 and the contact surface is set so that the interval is equal to or slightly smaller than the plate width of the attaching surface 3a. Thereafter, when the protruding member 4 is inserted into the groove 6, the body 5 and the attaching member 3 are elastically coupled and engaged. Thus, the secure attachment is obtained so that looseness, deviation and disengagement can be prevented when large vibration occurs.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve that can be easily dismounted from an internal combustion engine and prevents damage during dismounting.SOLUTION: A cylinder member 20 includes a fuel introducing section 25 for introducing a fuel from a fuel supply source, a cylinder section 26 connected to the fuel inlet section 25, a second cylinder member 22, a third cylinder member 23, a cylinder section 27, and a bottom 28 that closes an end of the cylinder section 27 opposite the fuel inlet section 25 and that has an injection hole 281 formed therein. The cylinder member 20 is mounted on an engine to expose the bottom 28 to a combustion chamber. A valve member 30 is disposed so as to be reciprocable inside the cylinder member 20, and opens and closes the injection hole 281 by separating from or coming in contact with the bottom 28. An electromagnetic drive unit 40 generates a magnetic field when power is supplied, to attract the valve member 30 in a valve-opening direction. A specific shape section 61 is formed to be recessed radially inward from an outer wall of the cylinder section 26 at an end on the side of the fuel inlet section 25.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel feeder to prevent a resin fitting member from being charged. SOLUTION: A flange member 12 and a fuel discharge pipe 14 are integrally formed of an insulating resin with a conductive filler mixed therein. The fuel discharge pipe 14 leads the fuel discharged from a fuel pump outside a fuel tank 2. An electric connector 20 is formed by inserting a power source terminal 24 and a grounding terminal 26 in an insulating resin material 22. The grounding terminal 26 is electrically and directly connected to a protruded part 13 of a flange member 12. The power source terminal 24 and the grounding terminal 26 are electrically connected to an electric connector of the fuel pump via a lead wire. Charges are moved from the charged fuel flowing in the fuel discharge pipe 14 and a bellows pipe 48, and the charges are moved from the flange member 12 to the grounding terminal 26.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel holding tank capable of reducing the quantity of a fuel spouted from a fuel pump and of preventing the outflow of the fuel to the fuel tank, and to provide a fuel feeding device using it. SOLUTION: The tank body 12 upper than a fuel outlet 15 is sealed excluding a negative pressure port 16. Screen meshes 20, 21 and 22 cover a fuel inlet 14, the fuel outlet 15 and the negative pressure port 16, respectively, and have fine through holes capable of interpenetrating both sides in the film thickness direction in their entire surfaces. When a jet pump 30 injects the fuel from an exhaust nozzle 31, the periphery on the outlet side of the exhaust nozzle 31 is set to negative pressure, so that the fuel in the fuel tank 1 flows into the tank body 12. Even if the jet pump 30 does not spout the fuel nor generates negative pressure, gas does not pass the screen mesh 22 wet with the fuel, so that the fuel in the tank body 12 does not flow out from the fuel inlet 14.

Abstract: PROBLEM TO BE SOLVED: To provide a packing for a fuel supply device of an engine of low material cost having excellent sealing performance to gasified fuel and having excellent sealing performance even at a very low temperature. SOLUTION: This packing 10 is formed in two-layer structure comprising an inner layer 13 formed of fluorine-contained elastomer of high cost with excellent gas impermeability, and an outer layer 14 formed of synthetic rubber of low cost with excellent gas impermeability even at the very low temperature. In normal use, the leakage of gasified fuel is effectively prevented by the fluorine-contained elastomer constituting the inner layer 13, and at the very low temperature, the leakage of gasified fuel is prevented by the outer layer 14 formed of synthetic rubber instead of the inner layer 13 formed of the fluorine-contained elastomer slightly lowered in performance. In this packing 10, the high-cost fluorine-contained elastomer is not used for the whole part, so that the large increase of manufacturing cost can be prevented.
