圧接するように形成してある。 The cap 5 is provided with a diaphragm type seal 10 on the inside.
0, as shown in Figure 3, the central part is a chevron-shaped overhang 1
1, an annular packing 12 is fixed to the lower surface around the hem, and the top of the chevron-shaped projecting part 11 is connected to the top plate part 5a.
A diaphragm-shaped sealing body 10 is provided inside the cap 5 in a floating state in a free state so that it can freely come into contact with the inner surface, and protrusions 13, 13, .
is provided to prevent the diaphragm type sealing body 10 from falling off. The annular packing 12 is formed so as to come into pressure contact with the opening edge 3a of the cylindrical wall 3 when the cap 5 is closed on the injection port 2.
図中、１４はリリーフ弁、１５は空気出入路、
１６はキヤツプ５に設けた引掛けフツク、１７は
筒壁部３に設けた引掛け具である。 In the figure, 14 is a relief valve, 15 is an air inlet/outlet passage,
16 is a hook provided on the cap 5, and 17 is a hook provided on the cylindrical wall portion 3.
本考案装置は前記のように構成したので、第４
図に示したように、取付軸６を支点としてキヤツ
プ５を反時計方向に回動させ、燃料注入具(イ)を筒
壁部３の開口から装入し、燃料を注入する。 Since the device of the present invention is configured as described above, the fourth
As shown in the figure, the cap 5 is rotated counterclockwise about the mounting shaft 6, and the fuel injector (a) is inserted through the opening in the cylinder wall 3 to inject fuel.
注入完了後、燃料注入具(イ)を取出すと、キヤツ
プ５は閉まり習性を有するから時計方向に回動
し、キヤツプ５により注入口２は閉鎖される。 When the fuel injection tool (a) is removed after injection is completed, the cap 5 has a tendency to close, so it rotates clockwise, and the injection port 2 is closed by the cap 5.
このようにキヤツプ５が閉鎖状態となつたとき
は、ダイヤフラム形密封体１０の山形張出部１１
の頂点が天板部５ａ内面に当節し、ダイヤフラム

圧接し、ダイヤフラム作用によつて強力な圧接が
得られるからキヤツプ５が閉状態で僅かの傾きが
あつても環状パツキング１２によるシール面圧は
均等になる。 When the cap 5 is in the closed state in this way, the chevron-shaped protrusion 11 of the diaphragm-shaped sealing body 10
The apex of the cap 5 is in contact with the inner surface of the top plate portion 5a, and the annular packing 12 of the diaphragm-shaped sealing body 10 is pressed against the opening edge 3a, and a strong pressure contact is obtained by the action of the diaphragm, so that when the cap 5 is closed, there is a slight Even if there is an inclination, the sealing surface pressure by the annular packing 12 is equalized.
本考案は注入口の筒壁部開口に対するシール性

を未然に防止できる等の効果がある。 This invention has extremely good sealing performance against the opening of the cylinder wall of the inlet, and can even out the sealing surface pressure. When the cap is released from being held open, the cap automatically closes, leaving the inlet in the open state. Therefore, there are effects such as being able to prevent the intrusion of muddy water, sand, dust, etc.
