DETAILED DESCRIPTION OF THE INVENTION

[0044] In this detailed description, preferred embodiments of the new-generation fuel tank connection are described only for a better understanding of the subject and without having any limiting effect.

[0045] In the FIG. 1 and FIG. 2, the new-generation fuel tank connection subject to the invention is shown. According to the invention, the support piece (90) should be welded to the fuel tank roof (100) during manufacturing of fuel tank. There are holes (62) on the sealing gasket (60) to attach this sealing gasket on the tank with connection pieces (30). The sealing gasket (60) is connected to the support piece (90) with the connection pieces (30) through these holes (62). The new-generation sealing gasket (60) should be produced with a mold having a desired hardness. This is the most important piece in the designed system and this is made of materials suitable with fuel.

[0046] This serves as leaking and vibration damping between the fuel tank and one-piece sealing element (20) installed later in it. There is a channel (61) structure inside (63) to increase sealing. The inner surface (63) of the gasket (60) where channels (61) are located has a conical (64) structure for the ease of mounting gasket sealing and sealing element (20). One-piece welded sealing element (20) should be produced in desired conicity (22). The stamp (110), which is attached on the new-generation sealing gasket (60) to press equally on the tank and is preferably made of aluminum, is preferably made of 3 mm thickness in the design developed. By taking into consideration tightening portion of the gasket (60) under the stamp (110), it has been designed in a wider diameter than the gasket (60). Herein, insert pieces (70) are nailed on the connection piece slots of the support piece (90) welded inside the tank and used to prevent deterioration of the tooth structures of the aluminum surfaces.

[0047] A hole should be made in the vehicle roof plate (130) to pass through the sealing element (20) and the support (120) should be welded to attach the connection pieces. Fuel filter (80) is attached inside the sealing element (20) preferably made of aluminum and is tightened with a clamp (50). The clamp (50) has been designed especially for preventing leakage of diesel oil between sealed gasket (60) and sealing element (20). Inner gasket of the clamp (50) is made of a material which is suitable with fuel and which does not damage the outside of sealed gasket (60). All the surfaces of the clamp (50) are ensured to be equally tightened. The part where sealing element (20) enters into sealed gasket (60) is made in conical (22) structure.

[0048] With the newly developed system, a special sealed gasket (60) has been designed for the fuel filling neck. The sealed gasket (60) is attached to the roof plate (100) without the fuel tank being placed inside the vehicle. After the sealed gasket (60) is attached on the fuel tank, it is tightened on the tank with stamp (110). The sealing clamp (50) is loosely attached on the new-generation sealed gasket (60). The fuel tank is secured by matching the sealed gasket (60) located on the fuel tank placed inside the vehicle and the opening located in the body plate. One-piece welded sealing element (20), which is developed from vehicle roof into the sealed gasket (60) and has a conical (22) structure, is placed. Mold-release silicon or petrolatum can be used during mounting in order not to damage fuel and sealed gasket (60). Sealing element (20) is connected to the support (120) located on vehicle roof (130) with connection pieces (30) through connection holes (23). Sealing clamp (50) is tightened inside the vehicle and sealing is provided. Wherein gasket (40) provides sealing between sealing element (20) and support (130) welded to vehicle roof and preferably is made of nitrile material suitable with fuel.

[0049] The sealing element (20) shown in FIG. 4 and FIG. 5 serves as filling cover (10) and sealing element. The conicity (64) of the sealed gasket (60) and the conicity (22) of the sealing element (20) match. In alternative embodiments of the sealing element (20), there are channels (21) on conical (22) part in order to increase sealing. There are channels (61) inside the new-generation sealed gasket (60) showed in FIG. 3 in order to increase sealing.

[0050] Prototypes have been produced and tested for new-generation fuel system. For the sealed gasket (60) used, various harnesses were tested as neoprene and nitrile. Tests made: [0051] Mounting of fuel tank has been completed and air of 0.3 bar have been provided inside tank. In this test, Nitrile and Neoprene sealed gaskets (60) have been used. As a result of the test, there is no air leakage. [0052] The tank has been completely filled with diesel oil and kept in reverse for 1 week. As a result of the test, there is no fuel leakage. [0053] Nitrile and neoprene gaskets have been reversed and have been gradually subject to vibration and shake. As a result of this test, there is also no fuel leakage.

[0054] The Results obtained as a result of the tests made are as follows; [0055] A new sealed gasket (60) produced with different degrees of hardness was observed;

[0056] Considering the mounting, it was observed that Neoprene gasket was more easily mounted but deformed too much when the bolts were tightened since it remained soft (40 shore). After the tests performed by reversing them, it was observed that the traces of bolt slot left a permanent trace similar to deformation on the Neoprene gasket. It was observed that nitrile gasket being harder was not very difficult to mount and its degree of hardness (50 shore) was more suitable for the place of use. [0057] Welded (aluminum) sealing element (20) was observed;

[0058] The fuel filling neck produced as having channel (21) was mounted. It was observed that the channels may damage the gasket during demounting. [0059] Sealing clamp (50) was observed; A special clamp gasket was used in order to tighten equally from every surface. Air leakage was observed with or without clamp attached in the 0.2 bar air test. In the tests made by reversing, it was observed that fuel proceeds to the surface which clamp tightens and the clamp holds fuel. It was observed that the gasket clamp can be selected slightly smaller than outer diameter of gasket surface and shortening the bolt would be easier in terms of mounting. The clamp was selected in such a way to be stainless and to be tightened from one side.

[0060] Protection scope of this application has been determined in the claims and it cannot be limited to those explained above for illustrative purposes. It is apparent that a person skilled in the art can introduce a novelty introduced in the invention by using similar configurations and/or apply this configuration in other fields with similar aims used in the relevant technique. Therefore, it is apparent that such configurations can be deprived of novelty and criteria regarding exceeding the state of art.
