分な解決がなされていない。(Prior art) Fuel tanks for vehicles have a saddle formed by protruding the center part of the bottom in the vehicle width direction upwards, and are manufactured to allow propeller shafts, etc. to pass through the lower part of the saddle. When it is below the saddle, it separates into concave parts on both sides of the saddle, and if a single fuel pump is used like a fuel tank without a saddle, there is a drawback that it will run out of fuel even though there is still fuel left. For this reason, Utility Models 60-49021, 60-46436, 60-62323, and
There have been many proposals, such as those shown in various publications such as No. 60-141472, in which a fuel pump or suction tube of the pump is installed on one side of the saddle, and about 80% of the fuel pumped to the engine side by the fuel pump is Place the return tube that returns to the fuel tank on the one side, or insert the suction tubes of the fuel pump on both sides to prevent the fuel level from dropping or Some solutions have been taken, such as using a floating member to sense the shortage and automatically closing the valve of the suction tube on one side, but in a configuration that uses a return tube, the amount of return fuel is Since it is a dependent device, it is unreliable, and when using a floating member, two are required, making the device expensive, and no satisfactory solution has been found.

る。 A feeding box 8 of the fuel feeding pipe 7 which passes over the saddle 2 and opens to the one side 3 is provided on the other side 4, and fuel is fed in the direction of the feeding box 8 by impact from different directions to the outside of the feeding box 8. A guide bulkhead 9 for concentrating fuel is installed on the other side 4, and a plurality of check valves 10 are installed in the sending box 8, which are guided by the guide bulkhead 9 and open by the pressure of the concentrated fuel.
will be established. In this embodiment, the fuel on the other side 4 is concentrated in the rear direction in the running direction due to the impact when the vehicle starts running and accelerates, the fuel is concentrated in the front side in the running direction due to the impact during deceleration, and the fuel is concentrated in the front side in the running direction due to the impact when the vehicle starts to run. As shown in the diagram, two guide bulkheads 9 are installed to prevent the impact from concentrating on the
will be established. In the present invention, the passage of fuel concentrated by the guide partition wall 9 becomes narrower as it approaches the delivery box 8. The check valve 10 is provided inside the outer wall of the shipping box 8 in correspondence with the fuel passage partitioned by the guide partition wall 9.

料送り管７により一側３に吐出される。 In this embodiment, fuel concentrates in the passageway and collects in the delivery box 8 due to the reaction of the vehicle starting acceleration, and fuel concentrates in the passageway and collects in the delivery box 8 due to the reaction of the vehicle's deceleration, and when the vehicle turns to the right, fuel is collected from the right direction. Fuel concentrates in the passage and collects in the delivery box 8, but does not concentrate when turning left. As the fuel concentrates in one of the passages and the passage gradually narrows, the rate of concentration increases, and the check valve 10 corresponding to the passage where the fuel concentrates opens inward due to the fuel pressure, causing the feed box to close. 8, the other check valves do not open due to the pressure inside the box 8, and the fuel that has entered the box 8 is discharged to one side 3 through the fuel sending pipe 7.

しになる。 If the outlet of the feed pipe 7 is placed near the bottom of one side 3, when the feed pipe 7 is filled with fuel, the feed pipe 7 will generate a siphon function, and the fuel on the other side 4 will flow even when there is no reaction from acceleration or deceleration. is always fed to one side 3, and the amount of conveyance becomes larger. At this time, the check valve 10 is left open.

ンジンに送ることができる効果を有する。(Effects) The present invention provides a feeding box 8 for the fuel feeding pipe 7 that passes over the saddle 2 and opens on the one side 3 on the other side 4, and the feeding box 8 is damaged by impact from several different directions on the outside of the feeding box 8. A guide bulkhead 9 is installed on the other side 4 to concentrate the fuel in the direction of , and the sending box 8 is equipped with several check valves 10 that are opened by the pressure of the fuel induced by each bulkhead 9. It is a fuel tank with a distinctive saddle 2, and although the amount delivered at one time is not significantly large,
By repeating the fuel feeding described above, the fuel on the other side 4 is sent to the one side 3, and as in the case of a fuel tank without a saddle,
This has the effect that the fuel in the fuel tank with a saddle can be sent to the engine by the fuel pump.
