【考案の詳細な説明】
本考案は、自動車等の燃料タンクの注入口の改良に関す
る。[Detailed Description of the Invention] The present invention relates to an improvement of an injection port for a fuel tank of an automobile or the like.
自動車の燃料タンクに燃料を注入する場合、該タンクの
注入口に注入ガンを挿入して燃料注入を行い、満タンに
なると注入ガンの自動給油停止装置が動作し、給油が終
了する。When injecting fuel into a fuel tank of an automobile, an injection gun is inserted into the injection port of the tank and the fuel is injected. When the tank is full, an automatic refueling stop device of the injection gun is activated and refueling is completed.
かかる燃料注入口は、従来第１図に示す様な構造になっ
ている。Conventionally, such a fuel injection port has a structure as shown in FIG.
図において、１は車体に設けたインレットボックス、２
は注入口に挿入した注入ガン、３はフィラーネック、４
は給油管、５はフィラーホースである。In the figure, 1 is an inlet box provided on the vehicle body, 2
is the injection gun inserted into the injection port, 3 is the filler neck, 4
is an oil supply pipe, and 5 is a filler hose.
即ち、従来はフィラーホース５内に給油管４の上部を嵌
入し、該給油管の上端面４ａが内側に肉厚骨だけ突出し
て存在する構造となっている。That is, conventionally, the upper part of the oil supply pipe 4 is fitted into the filler hose 5, and the upper end surface 4a of the oil supply pipe has a structure in which only the thick bone protrudes inward.
従って、図示の様に注入ガン２の先端が給油管の上端面
４ａ近くに位置した場合は、燃料は該端面４ａに当たり
、この端面４ａが抵抗となって注入ガンの自動給油停止
装置が作動し、スムーズな給油が妨げられるという不都
合があった。Therefore, when the tip of the injection gun 2 is located near the upper end surface 4a of the fuel supply pipe as shown in the figure, the fuel hits the end surface 4a, and this end surface 4a acts as a resistance, causing the automatic fuel stop device of the injection gun to operate. , there was an inconvenience that smooth refueling was hindered.
本考案の目的は、上記事情に鑑み、給油途中に注入ガン
の自動給油停止装置が作動する虞れがなく、スムーズに
給油することができる燃料タンクの注入口を提供するこ
とにあり、その要旨は、フィラーホース内に給油管の上

肉盛部を下方に向けて小径となるテーパー状に形成し、
該肉盛部の下端部若しくはその近傍の内径を給油管の内
径と同一かそれより小にしたことを特徴とする燃料タン
クの注入口にある。In view of the above circumstances, the purpose of the present invention is to provide a fuel tank filler port that allows smooth refueling without the risk of the automatic refueling stop device of the injection gun operating during refueling. At the injection port of the fuel tank, where the upper part of the fuel supply pipe is inserted into the filler hose, a built-up part is provided near the upper end of the fuel supply pipe in the filler hose, and the built-up part is directed downward to form a small diameter Formed into a tapered shape,
The fuel tank inlet is characterized in that the inner diameter at or near the lower end of the built-up portion is equal to or smaller than the inner diameter of the fuel supply pipe.
以下、図面に示す実施例を参照しながら本考案を詳細に
説明する。Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
第２図は本考案に係る注入口の一実施例を示す断面概念
図である。FIG. 2 is a conceptual cross-sectional view showing one embodiment of the injection port according to the present invention.
図において、１は車体に設けたインレットボックス、２
は注入口に挿入した注入ガン、３はフィラーネック、４
は給油管、５はフィラーホースであり、ここまでは第１
図に示す従来例と同様である。In the figure, 1 is an inlet box provided on the vehicle body, 2
is the injection gun inserted into the injection port, 3 is the filler neck, 4
is the oil supply pipe, and 5 is the filler hose.
This is similar to the conventional example shown in the figure.
本考案に係る注入口は、上記従来の注入口において、フ
ィラーホース５内の給油管４の上端部近傍に肉盛部６を
設け、該肉盛部６を下方に向かって小径となるなだらか
なテーパー状に形成し、かつ該肉盛部６の下端部若しく
はその近傍の内径を給油管４の内径と同一かそれより小
にして戊る。The inlet according to the present invention differs from the above conventional inlet by providing a built-up part 6 near the upper end of the oil supply pipe 4 in the filler hose 5, and forming the built-up part 6 into a shape that gradually decreases in diameter downward. It is formed into a tapered shape, and the inner diameter at or near the lower end of the built-up portion 6 is made equal to or smaller than the inner diameter of the oil supply pipe 4.
本実施例においては、フィラーホース５の内側であって
、フィラーネック３の下端と給油管４の上端との間に上
記肉盛部６を設け、該肉盛部６の下端部内径を給油管４
の内径より小とし、かつ肉盛部６の下端部に給油管４の
上端部を当接させである。In this embodiment, the built-up part 6 is provided inside the filler hose 5 between the lower end of the filler neck 3 and the upper end of the oil supply pipe 4, and the inner diameter of the lower end of the built-up part 6 is connected to the oil supply pipe. 4
, and the upper end of the oil supply pipe 4 is brought into contact with the lower end of the built-up portion 6.
本考案に係る注入口は上記の如く構成されているので、
注入ガン２から注入される燃料は肉盛部６に沿って給油
管４内にスムーズに流れ込み、給油管４の上端面４ａに
当る虞れがない。Since the injection port according to the present invention is configured as described above,
The fuel injected from the injection gun 2 smoothly flows into the fuel supply pipe 4 along the built-up portion 6, and there is no risk of it hitting the upper end surface 4a of the fuel supply pipe 4.
従って、給油途中に自動給油停止装置が作動する虞れが
なく、スムーズに給油することができると共に、給油中
安心して他の作業を行うことができる。Therefore, there is no risk that the automatic refueling stop device will operate during refueling, and it is possible to refuel smoothly and perform other tasks with peace of mind while refueling.
また、従来の注入口に容易にかつ安価に適用できる。Moreover, it can be easily and inexpensively applied to conventional injection ports.
