Definitions

  • This invention relates to a fuel feed apparatus and, more particularly, it relates to a technology that can be effectively applied to an in-tank type fuel feed apparatus having a fuel pump arranged inside a fuel tank.
  • in-tank type fuel feed apparatus having a fuel pump and a strainer arranged inside a fuel tank are popularly used for motor bicycles and motor cars.
  • Many fuel feed apparatus of the so-called in-tank type of motor bicycles and motor cars comprise a sub-tank arranged within the fuel tank that operates to prevent any possible interruption of fuel supply that can arise when the bicycle or the car drives up a slope of is subjected to vibrations.
  • a box-like or sleeve-like reservoir is arranged as sub-tank in the fuel tank and the fuel pump is adapted to suck fuel from the sub-tank so that the fuel suction port may not emerge from the fuel in the tank and exposed to air if the motor bicycle or the motor car is inclined while in motion.
  • fuel may be supplied on a stable basis even when the motor bicycle or the motor car is shaken.
  • motor bicycles and motor cars provided with such a fuel feed apparatus can be tilted for a prolonged period of time, during which fuel is fed to the engine.
  • motor bicycles can often be forced to prance on the rear wheel or rest on a side prop stand in an inclined state, while fuel has to be fed to the engine continuously.
  • the fuel in-take port can be found very low and fuel can flow out therethrough, although the sub-tank is provided, to make it no longer possible to supply fuel to the engine for a prolonged period of time on a stable basis.
  • one or more than one filter members such as paper filters and/or synthetic resin filters are contained in the strainer in order to filter the fuel discharged from the fuel pump.
  • the fuel passing through the filter can easily generate static electricity due to its friction with the filter materials.
  • the fuel can give rise to turbulence before and after passing through the filter to cause friction between the synthetic resin case and fuel, which also consequently generates static electricity.
  • Japanese Patent Application Laid-Open No. 8-232792 proposes an in-tank type fuel pump apparatus wherein grounding lead wires are connected to the fuel filter to allow the generated static electricity to flow to the ground.
  • a lead wire is connected to each of the components housed in the tank. Then, the lead wires are electrically connected with the vehicle wire harness so that the components are grounded and prevented from becoming electrically charged.
  • Japanese Patent Application Laid-Open No. 10-220315 proposes the use of a filter case made of an electrically conductive material so that the generated static electricity may be discharged into the fuel in it from the outer peripheral surface thereof.
  • the above identified patent document also discloses a technique of connecting lead wires to the electrically conductive filter case at an end and to a grounding electrode outside of the fuel tank at the other end in order to allow the static electricity generated in the filter case to flow to the ground. If the fuel tank is made of metal, the lead wires are also connected to it so that the static electricity generated there may directly flow to the ground.
  • fuel tanks are generally provided with a warning sensor comprising a thermistor for notifying the driver with the volume of fuel left in the fuel tank when the fuel in the tank falls below a certain threshold level.
  • a warning sensor comprising a thermistor for notifying the driver with the volume of fuel left in the fuel tank when the fuel in the tank falls below a certain threshold level.
  • electricity flows through such a thermistor at a very low rate and hence the thermistor generates heat to a small extent.
  • the fuel cools the thermistor and hence its temperature would not rise. If, on the other hand, the fuel level falls to make the thermistor emerge from the fuel, the fuel no longer cools it and its temperature rises.
  • the electric resistance of a thermistor changes as its temperature. Therefore, the volume of fuel left in the tank can be detected by detecting the change in the electric resistance of the thermistor.
  • thermistors are popularly used as the above described sensors.
  • lead wires connected to the thermistor are also arranged in the fuel tank so that the signal from the thermistor is received by way of the lead wires to detect the volume of fuel left in the tank.
  • Another object of the present invention is to provide a fuel feed apparatus having a simple configuration with a reduced number of components that requires only a simplified wiring operation.
  • a fuel feed apparatus to be used for a motor bicycle or a motor car, said apparatus comprising a reservoir containing a fuel pump therein and adapted to store fuel to be sucked by said fuel pump, said reservoir having a fuel in-take port for introducing fuel into the inside thereof, said fuel in-take port being arranged at a position where it is made to face upward when the body of the motor bicycle or the motor car is inclined.
  • said fuel in-take port may be so arranged as to face upward when the motor bicycle is made to rest on the side prop stand.
  • said fuel in-take port may be so arranged as to face upward when the motor bicycle is made to prance.
  • the motor bicycle can feed the engine with fuel stably for a long period of time.
  • the inside of the fuel in-take port may have a labyrinth structure. Then, fuel will be further prevented from flowing out through the fuel in-take port.
  • a strainer for filtering the fuel discharged from said fuel pump, a sensor for detecting the amount of the residual fuel in the fuel tank and a sensor holder made of an electrically conductive material and arranged in said fuel tank to hold said sensor, said sensor holder having a strainer-connecting section connected to said strainer and an earth-connecting section electrically connected to the grounding terminal of said sensor.
  • the sensor holder can be commonly used as the grounding terminal of the strainer and also as that of the sensor to eliminate not only the grounding wire of the strainer but also the step of arranging the grounding wire of either the strainer or the sensor.
  • both the number of parts and that of processing steps can be reduced in the process of building the apparatus.
  • a thermistor may be used for said sensor, additionally, said sensor holder may be formed by using a metal wire having said strainer-connecting section formed at an end thereof and said earth-connecting section formed at the opposite end thereof.

  • the inside of the unit base 4 of the apparatus 1 is empty and adapted to contain the pump 5 and other components and operate, at the same time, as a sub-tank 16.
  • the unit base 4 functions as reservoir so that the fuel 42 sucked up by the pump 5 is temporarily stored in the unit base 4 in order to avoid any improper supply of fuel that can arise when the motor vehicle drives up a slope or is fiercely shaken.
  • conventional sub-tanks comprise a plurality of components typically as shown in FIG. 10, that of apparatus 1 of the present invention comprises only a unit base 4.

  • a motor bicycle may frequently be required to stand on the rear wheel and/or tilt sideways and supported by its prop stand while being fueled. Additionally, the center of gravity of a motor bicycle moves to the rear wheel side and it may prance on the rear wheel when accelerated. Still additionally, the front wheel side of a motor bicycle is higher than the rear side when it goes up a slope. Under any of these conditions, the engine requires to consume more fuel than ever.
  • the port 17 of the apparatus 1 is arranged at a position that does not allow fuel to flow out when the body of the motor bicycle is tilted or at a position where the port 17 will face upward when the body of the motor bicycle is tilted. With this arrangement, fuel is prevented from flowing out of the sub-tank 16 even when the motor bicycle stands up on the rear wheel or when it prances.
  • the opening 17a of the port 17 of this apparatus 1 is arranged at a position close to the front end of the body and opposite to the side where the prop stand is provided so that it may face upward when the front of the motor bicycle faces upward and hence fuel may be prevented from flowing out under any of the above identified conditions.
  • While the location of the fuel port 17 is selected by taking both the situation where the motor bicycle is made to stand on the rear wheel and the situation where the motor bicycle is made to rest on its prop stand, it may alternatively be selected by dominantly taking either of the situations into consideration. If the situation where the motor bicycle is made to stand on the rear wheel is considered to be the dominant factor, the port 17 will be arranged at a position close to the front of the motor bicycle. If, on the other hand, the situation where the motor bicycle is tilted and made to rest on its prop stand is considered to be the dominant factor, the port 17 will be arranged at a position opposite to the side of the prop stand.

Therefore, the thermistor 24 detects the volume of fuel left inside the tank by detecting the change in the ambient temperature and, when the fuel 42 in the fuel tank goes under a certain threshold level, it produces a warning by notifying the driver with the fact that fuel is running out.
  • FIG. 9 is a schematic lateral view illustrating how the thermistor 24 is fitted and wired.
