バツフルプレート3が斜面を形成していること
と、連通管7を有すること等が異なる。 One example of a conventional fuel tank of this type is shown in FIG. 1, and another example is shown in FIG. In the one shown in FIG. 1, a buff-full plate 3 is placed on the convex portion 1a of the upper surface of the tank to form an air chamber 4, and the air inside the air chamber 4 is guided to the outside of the tank by a breather tube 2. The one in Figure 2 is the same as above, but
The difference is that the buff-full plate 3 forms an inclined surface and that it has a communication pipe 7.
しかし上記のものには次の欠点がある。 However, the above method has the following drawbacks.

リーザチユーブ2から液が外部へ流出する。(1) If liquid enters the air chamber 4 when the vehicle turns, etc., but there is a disadvantage that the liquid shakes due to the vibration of the car body and scatters at the mouth 2b of the breather tube 2, and the pressure inside the air chamber increases. Liquid flows out from the breather tube 2 to the outside.
(2) ブリーザチユーブ2がタンク上面外部に配管

い。 2 is a breather tube, which is piped inside the upper surface of the tank 1 and inserted into the air chamber 4 to form a U-shaped portion 2a along the end surface of the convex portion 1a, and an opening 2b is provided at the end thereof. . It is preferable that the opening 2b opens outside the left and right inclined liquid levels B, B caused by left and right turning, that is, in the upper center as shown in the figure.

い方向に設けてある。 The end face of the full plate 3 is located at a predetermined height A higher than the liquid level when the tank is full, and a port 6 is opened on the end face, and a louver 5 is attached, and the direction of the louver 5 is The opening 2b of the breather tube is provided in such a direction that the inflow liquid from the port 6 does not directly splash into the opening 2b of the breather tube.
上記構成の場合の作用、効果について述べる。 The functions and effects of the above configuration will be described.
ブリーザチユーブ開口2b部への液の飛散と運
転による温度上昇のための圧力増大によつて液が
ブリーザチユーブ2から流出するのを防止する。 This prevents liquid from flowing out of the breather tube 2 due to splashing of the liquid to the breather tube opening 2b and an increase in pressure due to temperature rise during operation.
(1) ポート6の位置の選定とルーバ5の設定によ
り、動揺する液のブリーザチユーブ開口2b部
への直接的な飛散を防止できる。またエヤチヤ
ンバ4内へ液が入り難い。(1) By selecting the position of the port 6 and setting the louver 5, it is possible to prevent the agitating liquid from directly scattering to the breather tube opening 2b. Also, it is difficult for liquid to enter the air chamber 4.
(2) 急激な旋回による傾斜液面B、急加減速等に

によりブリーザチユーブ開口2b部への飛散は
ない効果がある。(2) Liquid enters the air chamber 4 due to the inclined liquid level B due to rapid turning, sudden acceleration and deceleration, etc., but even if the liquid swings, it is attenuated by the surrounding gentle slopes and is unlikely to scatter. In addition, even if it scatters, the step C
This has the effect of preventing scattering to the breather tube opening 2b.
(3) ブリーザチユーブ2がU字形状のため、万一
液がブリーザチユーブ開口2b部へ飛散しても
流出し難い効果もある。(3) Since the breather tube 2 is U-shaped, even if the liquid splashes into the breather tube opening 2b, it is difficult to flow out.
(4) ブリーザチユーブ2はタンク上面の内側に配
管されているので、一般の乗用車ではタンク上
部のトランクスペース、後席居住性を阻害せず
コンパクトな構造が得られる。(4) Since the breather tube 2 is piped inside the top surface of the tank, a compact structure can be obtained in a general passenger car without interfering with the trunk space above the tank or the comfort of the rear seats.
(5) 満タン時の液面からのバツフルプレート高さ

ない)が得られる。(5) Breather with the height A of the full plate from the liquid level when the tank is full, and the inclined liquid level B due to sudden turns, etc. (this also includes the liquid level inclined forward and backward due to acceleration and deceleration) A sufficient breather effect (liquid does not flow out) can be easily obtained by selecting the tube opening position.
(6) タンク内部に一枚のバツフルプレート3を設
けるのみで、安価な生産性の高いブリーザ構造
が得られる。(6) By simply providing one buttful plate 3 inside the tank, an inexpensive breather structure with high productivity can be obtained.
