この考案は、オートバイ等の車両用燃料タンク
の燃料移動防止装置に関する。[Detailed Description of the Invention] This invention relates to a fuel migration prevention device for a fuel tank for a vehicle such as a motorcycle.
オートバイ等の車両では、燃料タンクに燃料を
入れておき、この燃料をエンジンに供給して運転
する。車両が加速及び減速を行うと、燃料タンク

ク下端に設けた取出口が露出して、燃料が流れな
くなつて、エンジンストツプを起すことがある。
特に、燃料タンク内の燃料残量が少ない場合に
は、燃料の移動が容易で、燃料切れが起り易い。
これをさけるため、取出口の上側に複数の流通孔
を設けた移動防止板を張り、燃料の移動を押える
ようにしているが、急減速のような場合は、慣性
も大きく、流通孔から燃料が強く吹出して、燃料
切れが起ることがあつて具合が悪い。 Vehicles such as motorcycles are operated by filling a fuel tank with fuel and supplying this fuel to the engine. When the vehicle accelerates and decelerates, the fuel in the fuel tank moves forward or backward due to inertia, exposing the outlet provided at the bottom of the fuel tank, preventing fuel from flowing, and causing the engine to stop. There is.
Particularly, when the remaining amount of fuel in the fuel tank is small, the fuel is easily moved and fuel runs out easily.
In order to avoid this, a movement prevention plate with multiple circulation holes is placed above the outlet to prevent the movement of fuel, but in the case of sudden deceleration, the inertia is large and the fuel flows through the circulation holes. It blows out strongly and sometimes the fuel runs out, which is bad.
この考案は、かかる点に鑑み改善したもので、
以下本考案を図面に示す実施例について説明す
る。 This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.
燃料タンク１は、下端に取出口２が設けられて

取出口２の上側には隙間を設けて移動防止板３が

つてタンクの後方に向つて漸次開口面積が大きく
なるように斜め上方に向つて傾斜する覆い部４を
設けた窓孔５を設ける。覆い部４は、第２図及び
第３図に示すように、左右及び後側に割線を入れ
て起すか、第４図及び第５図に示すように後側だ
けに割線を入れて、逆凹字状になるように打出し
て設ける。尚、オートバイでは取出口２は、燃料
タンクの後部にあるものが殆んどで、加速時に燃
料が後側に移動する場合の影響は殆んどない。 The fuel tank 1 has an outlet 2 at its lower end and is connected to a carburetor of the engine via a pipe.
A movement prevention plate 3 is stretched above the outlet 2 with a gap provided therebetween. The movement prevention plate 3 is provided with a window hole 5 provided with a cover portion 4 that slopes obliquely upward so that the opening area gradually increases toward the rear of the tank by punching. The cover part 4 can be raised up with dividing lines on the left, right and rear sides as shown in Figures 2 and 3, or it can be raised up with dividing lines only on the rear side as shown in Figures 4 and 5. It is stamped out in a concave shape. Incidentally, in most motorcycles, the outlet 2 is located at the rear of the fuel tank, and there is almost no effect when the fuel moves to the rear during acceleration.
しかして、車両がブレーキして減速すると、燃
料タンク１内の燃料は、慣性によつて前側に移動

合には、燃料の移動が自由にできる。取出口２の

けてあつて、燃料は、後側に吹出すことになり、
エネルギーが消耗して吹出し量を少くすることが
できる。こうして、取出口２が露出して、燃料切
れが起つてエンジンストツプが生ずることを防ぐ
ことができる。 When the vehicle brakes and decelerates, the fuel in the fuel tank 1 moves forward due to inertia. Particularly when the remaining amount of fuel in the fuel tank 1 is small, the fuel can be moved freely. The fuel above the outlet 2 hits the movement prevention plate 3 and is prevented from moving. However, fuel will blow out from the fuel distribution window hole 5, but since the cover part 4 is provided on the upper front side, the fuel will blow out to the rear side.
Energy is consumed and the amount of air blowing can be reduced. In this way, it is possible to prevent the engine from stopping due to the outlet 2 being exposed and running out of fuel.
以上説明したように、この考案は、燃料タンク
下端の取出口の上側に移動防止板を張ると共に、
該移動防止板に打出しによつて前上側に覆い部を
設けた窓孔を設けたので、減速時に窓孔から燃料
が吹出して前側に移動するとき、覆い部で燃料の
移動エネルギーを消耗させることができて、吹出
し量を少く押えることができる。このため取出口
が露出するこがなくて、燃料切れによるエンジン
ストツプを防ぐことができる。又、覆い部は、移
動防止板を打出してできるので、材料が余分にか
かることもなく、安価にできる。 As explained above, this idea involves placing a movement prevention plate above the outlet at the bottom of the fuel tank, and
The movement prevention plate has a window hole with a cover part provided on the upper front side by punching, so when fuel blows out from the window hole and moves to the front side during deceleration, the moving energy of the fuel is consumed in the cover part. This allows the amount of air to be blown out to be kept low. This prevents the outlet from being exposed and prevents the engine from stopping due to fuel exhaustion. Moreover, since the cover part is made by stamping out the movement prevention plate, no extra material is required and the cost can be reduced.
