【発明の詳細な説明】 本発明は燃料タンクの満杯量規制装置に関する。[Detailed description of the invention] The present invention relates to a fuel tank fullness regulating device.
燃料タンクは外気温度の上昇による燃料の溢流金時ぐた
め、タンク内上層部に所定容量の空気室金膜ける必要が
あシ、この空気容量確保のため、燃料の満杯量を規制す
る必要がある。In order to prevent fuel from overflowing due to a rise in outside temperature, fuel tanks must have a metal membrane in the upper layer of the tank with an air chamber of a specified capacity.In order to secure this air capacity, it is necessary to regulate the amount of fuel that can be filled. There is.

When the liquid level of the fuel in the tank reaches a predetermined level as shown by the solid line in FIG. An air chamber with the required capacity (

カルタイプのものが用いられている。In addition, a unit gauge 4 is installed in the tank body 1 at a location offset from the air vent tube 3 so as to be able to detect the amount of fuel in the tank. A vertical type is used in which a moving float 6 is moved linearly downward along an electrical resistor base 7, and the amount of change in the liquid level is transmitted to a fuel gauge (not shown) as the amount of change in electrical resistance value. ing.

った。However, in such a conventional configuration, the air vent tube 3
Since the set position of the opening at one end is offset from the installed position of the float 6, which is provided in the unit gauge 4 and moves to follow changes in the liquid level, the tank body 1 is tilted by a vehicle such as a car. Even if the tank body 1 is installed horizontally, if the road surface at the refueling station is sloped, the liquid level will block the open end of the air vent tube 3, as shown by the chain line in Figure 1. Even if the fuel reaches the full level, the fuel level at the unit gauge 4 location has not reached the official level for detecting the full level, so the fuel gauge cannot properly indicate the full level. There was a problem with giving users a distrust fee. To solve this problem, it may be possible to place the unit gauge 4 close to the open end of the air vent tube 3, but if the internal pressure inside the tank body 1 rises during fuel injection, the filler tube 2 will be removed. However, since fuel is likely to be sucked back from the air vent tube 3, it could not be said that it is preferable.

するものである。In view of these conventional problems, the present invention has been developed by blocking the opening end of the air vent tube to regulate the full amount when a predetermined amount of fuel is refilled in the tank, even if the tank body is tilted, and by controlling the amount of fuel to be filled with the fuel gauge. It is an object of the present invention to provide a fuel tank full amount regulating device that can accurately indicate the full amount and match the amount of fuel in the tank with the amount indicated by a fuel gauge.

アベントチューブ開口端を閉塞するようにしである。In order to achieve the above object, in the present invention, one end opening of the air vent tube that regulates the amount of fuel in the fuel tank is penetrated through the earthen wall of the tank body and protrudes into the tank body. In a fuel tank equipped with a unit gauge for detecting liquid level, the opening end of the air vent tube is arranged within the movement locus of the float, and when the float is full of fuel, the opening end of the air vent tube is fixed by the float. It seems to be blocked.
以下、本発明の実施例を図面と共に前記従来の構成と同
一部分に同一符号を付して詳述する。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

One end opening t penetrates the earthen wall of the tank body 1 and is placed at a predetermined height position in the tank body 1, while a unit gauge 4 equipped with a float 6 that moves following changes in the liquid level is installed. By arranging the opening end of the air vent tube 3 directly under the open end of the air vent tube 3, the open end of the air vent tube 3 is placed within the movement trajectory of the float 6, and when the float 6 is full of fuel, the open end of the air vent tube 3 is moved by the float 6. It seems to be blocked.

させである。In this embodiment, a so-called vertical type gauge is used as the unit gauge 4, in which the float 6 moves linearly in the vertical direction along the electric resistor base 7 within the casing 5. Therefore, the air vent tube 3 is The casing and the lid 8 to which the resistors 5 and 7 are fixed are passed through.

。According to the above embodiment structure, even if the tank body 1 degree is in a horizontal state or an inclined state, when fuel is replenished into the tank body 1 and the liquid level reaches a predetermined height, the float 6 rises and the float The seal rubber 9 on the top surface of the air vent tube 3 closes the open end of the air vent tube 3 to regulate the full amount, and this full amount regulating position is not shown because it is the upper limit position of the float 6, that is, the full amount detection position. The fuel gauge can accurately indicate the full amount, and the amount of fuel in the tank can be perfectly matched with the amount indicated on the fuel gauge.
本実施例では、エアベントチューブ３、ユニットゲージ
４を、タンク本体１が傾斜しても液面レベルの変化が少

限定されるものでないことは勿論である。In this embodiment, the air vent tube 3 and the unit gauge 4 are arranged approximately at the center of the tank body 1, where the liquid level changes little even if the tank body 1 is tilted, but the present invention is not limited to this. Of course not.
１だ、ユニットゲージ４として液面測定を正確に行える

Surface weight and metal can be matched at all times, giving the user a sense of trust and improving the sense of quality.Also, since the air vent tube is blocked by the float, there is no risk of fuel sucking back. It has great practical effects, such as being effective even if
