TECHNICAL FIELD

The present invention relates to filling limiter for fuel tanks that facilitates to determine how much fuel it should be filled into fuel tanks of military vehicles, prevents from filling and carrying excessive fuel and dictates user how much fuel he/she should fill fuel by means of a simple ballcock system placed in the fuel filling filter.

In particular, the present invention relates to a filling limiter that indicates the fuel level in the tank and the fullness of the tank by means of the contact with the interior flange, such that it moves upwards and downwards in the filter due to buoyancy of the fuel.

STATE OF THE ART

In parallel with the development of technology, it is experienced significant developments in military systems. The main objects of these developments are the desire to make military vehicles faster, more comfortable, more useful, and safer. The main task of vehicle fuel tanks used in military vehicles is to preserve the fuel and to feed fuel to the engine. Fuel tanks should be formed of a material that does not react with the fuel. Materials are commonly aluminum and coated steels. The materials should lose their properties over time. Galvanized steel plates are not preferred, because they react with diesel. Welds of fuel tanks are one of the most important construction components. All welds should be examined subsequent to welding the fuel tanks. Fuel tanks are crucial systems for all vehicles. In the designs performed on armored vehicles, fuel tanks may be used dependent or independent from the vehicle. Nowadays, there is no application for fuel filling limiter in military vehicles in the market. It requires a filling limiter due to the fuel tank design in some vehicles. In case the design does not hinder the fuel filling level, there is no warning for the user how much fuel he/she should fill fuel in the tank. There is a shortcoming in the military vehicle sector, in which the use of the fuel nozzle is pretty different than in the automotive sector. It can provide the user with a maximum filling warning by means of a simple and cheap method.

Fuel filling filters used in the present technique function to filter dirt, filth, and particles in the fuel or that may pass through the opened filling neck to a certain extent.

Fuel excessively filled in the present technique prevents the heated fuel vapor from expansion and causes the fuel tanks to be pressurized.

Fuel excessively filled in the present technique is discharged through fuel vent based on the driving conditions and causes fuel leaks.

Air inlet to the fuel tanks in the present technique is troublesome for a full tank.

Users cannot determine how many liters he/she should fill fuel in the present technique.

In conclusion, the need for a novel, economical, useful ergonomic and more functional filling limiters for fuel tanks and insufficiency of the present solutions necessitate development in the related technical field so as to overcome the above-mentioned problems in the state of art.

DETAILED DESCRIPTION OF THE INVENTION

The detailed description relates to the inventive filling limiter for fuel tanks that facilitates to determine how much fuel it should be filled into fuel tanks of military vehicles, prevents from filling and carrying excessive fuel and dictates user how much fuel he/she should fill fuel by means of a simple ballcock system placed in the fuel filling filter.

In the present invention, it is tried to ensure to push and swim an object by forming an object with a less density than liquid or fuel by means of buoyancy of fluids. In principle, it is examined the Archimedes' cylinder and sea ballcocks. The floating capability of a mass on a liquid depends on the density of the material and the density of fluid contained therein. Stainless steel material and coating method are chosen due to mold cost and desires for adjustable sizes Furthermore, it is chosen a material that does not react chemically with the fuel.

It is used fuel filling filter (10) with different geometries, which comprises different particle preservation different from fuel tanks of all armored vehicles manufactured in the world. The filters (10) may be in a conical or cylindrical structure. The system is in a cylindrical structure and may be adjusted to fuel filters (10) seen in Figure 3 and Figure 5.

Figure 1 shows the inventive filling limiter for fuel tanks. In the present invention, the component is manufactured by means of the filter (10) manufacturing process. Herein, the flange (11) is an upper holding component of the fuel filling neck filter. It functions to hold the sieve (13) and cylinder (14) from their upper portions. It is in a staggered structure so as to prevent the filter (10) from falling into the tank through the filling neck. The lower holder (12) is the lower component of the fuel filter (10). It is the lower component that holds the sieve (13) functioning as a fuel filter and the cylinder (14). Flange (11) and lower holder (12) are provided to constitute the main structure. Flange (11) and lower holder (12) are preferably formed from stainless steel material. Figure 5 shows the sieve (13) and the cylinder (14). Herein, the sieve (13) is the main component with a small diameter that holds dirt, filth, and particles. The mesh structure of the component is selected based on the size of the particle that is desired to be caught. Since the cylinder in a mesh structure of the sieve

(13) used, it is used to strengthen the exterior structure. Sieve (13) and cylinder (14) are cut in desired sizes and positioned between the flange (11) and the lower holder (12) by means of the spot welding. Interior flange (15) in Figure 14 is added to the structure in the final stage. It is a component that indicates the limiting of the filling process through the contact after the ballcock (20) rises, wherein it also prevents it from getting out of the filter (10).

Ballcock (20) in Figure 2 is a swimmer newly added to the system, wherein it is manufactured from preferably stainless-steel material of 0,5 mm through the coating method. Ballcock (20) may be formed of aluminum material, however, it is observed that there is a strain on the weld of the extension part performed on its upper portion to adjust it to all designs. Ballcock moves downwards and upwards in the filter (10) by means of buoyancy of the fuel and indicates the fuel level in the tank. It indicates the fuel level, as the fuel is filled in. It states by means of its contact with the interior flange (15) that the fuel filling level is reached. Fuel is filled in by controlling the movement of the ballcock (20). After the ballcock (20) abuts on the level of the interior flange (15), it is required to cut off the fuel filling.

Figure 7 shows the alternative filling limiter for fuel tanks. Herein, the distance that should be covered by the ballcock varies due to the differences in the fuel tank designs. By means of the design, there is no problem in adjusting the size of the ballcock (20), on the contrary to Figure 8. There is no problem that the ballcock (20) manufactured in different sizes floats in the fuel. A test is performed by dying the ballcock (20) with a fuel-adjustable red color so as to perform a better fuel filling warning visually in the invention. However, the ballcock is not dyed, because it is considered that the dye may wear over time and may mix into the fuel.

The protection scope of the application is determined in the claims and it is to understand that it cannot be limited to the above-mentioned description for the purpose of illustration. It is clear that any innovation to be provided by a person skilled in the art by means of change in parts in form and use of similar embodiments can be applied in other areas for similar objects. Therefore, it is obvious that such embodiments will lack the criteria of inventive step.
