[0031] The fuel transmission system (1) comprises a body (2) that is located on the aircraft, at least one external tank (T) that is located on the body (2) and provides fuel accumulation, at least one valve (3) that is located between the body (2) and the external tank (T) and provides fuel transmission, at least one opening (4) that is located on the valve (3) and allows the fuel passage between the body (2) and the external tank (T), a gear region (5) that is located oppositely on the body (2) and on the valve (3) and allows the valve (3) to be mounted on the body (2), and at least one sealing element (6) that is located between the body (2) and the valve (3) in a way surrounding the valve (3) and prevents fuel from leaking into the body (2).

[0032] The fuel transmission system (1) which is the subject of the invention, comprises a sealing element (6) which prevents the fuel coming out of the opening (4) from reaching the gear region (5), and at least one coating (7) that is on the gear region (5) and provides galvanic compatibility between the body (2) and the valve (3) and thus prevents corrosion.

[0033] The fuel transmission system (1) comprises a body (2) that is located on the aircraft. An external tank (T) is located on the body (2). The fuel is located in the external tank (T) and the spare fuel in the external tank (T) is used in cases where the main fuel system is insufficient. At least one valve (3) is located between the body (2) and the external tank (T). The valve (3) provides fuel transmission between the body (2) and the external tank (T). There is at least one opening (4) on the valve (3) which allows fuel flow between the body (2) and the external tank (T). The valve (3) is mounted on the body (2) by means of the gear region (5) that is located opposite each other on the body (2) and the valve (3). There is at least one sealing element (6) between the body (2) and the valve (3). The sealing element (6) prevents fuel from leaking into the body (2). (FIG. 1)

[0034] The fuel transmission system (1) comprises a sealing element (6) that prevents fuel from reaching the gear region (5). The fuel is transmitted between the body (2) and the external tank (T) via the opening (4). The sealing element (6) surrounds the valve (3) in a way that limits the area of the valve (3) that is in contact with the fuel via the opening (4) and is preferably located both below and above the opening (4). At least one coating (7) with galvanic compatibility is applied on the gear region (5). The body (2) and the valve (3) are made of different materials. The gear region (5) that is located between the body (2) and the valve (3) is covered with coating (7) to prevent corrosion that may occur due to the body (2) and the valve (3) being made of different materials and to ensure galvanic compatibility. (FIG. 2)

[0035] In one embodiment of the invention, the fuel transmission system (1) comprises a coating (7) containing cadmium or zinc-nickel. A surface resistant to chemical reaction is provided between the valve (3) and the body (2) by means of the coating (7) containing cadmium or zinc-nickel alloys.

[0036] In one embodiment of the invention, the fuel transmission system (1) comprises a coating (7) produced in the form of a filler or paste, which provides adhesion. By means of the filler or paste form, it is easier for the coating (7) to adhere to the gear region (5) and provide effective protection.

[0037] In one embodiment of the invention, the fuel transmission system (1) comprises sealing elements (6) that are located on the valve (3) opposite each other, with an opening (4) between them. By means of the sealing elements (6), the flow of fuel between the body (2) and the valve (3) is limited by the opening (4). Thus, the fuel does not reach the gear region (5).

[0038] In one embodiment of the invention, the fuel transmission system (1) comprises a slot (8) that is on the body (2) and allows the valve (3) to be mounted on the body (2) by passing the valve (3) through it, and a gear region (5) that is located oppositely on the body (2) and the valve (3) so that it remains outside the external tank (T) when the valve (3) is passed through the slot (8), so that a standard sized insert gear can be used since there is a distance between it and the fuel. The valve (3) that is passed through the slot (8) is mounted on the body (2). When the valve (3) is mounted on the body (2), the gear region (5) is located outside the external tank (T) so that the fuel does not come into contact with the gear region (5). Since the gear region (5) is located on the upper part of the valve (3), standard insert gears can be used in the gear region (5). (FIG. 3)

[0039] In one embodiment of the invention, the fuel transmission system (1) comprises a gear region (5) surrounded and closed by the slot (8) wall.

[0040] In one embodiment of the invention, the fuel transmission system (1) comprises a gear region (5) having a sealing element (6) between it and the opening (4). Thanks to the sealing element (6), the fuel does not reach the gear region (5).

[0041] In one embodiment of the invention, the fuel transmission system (1) comprises a flange (9) on the valve (3) to which torque is applied so that the valve (3) can be mounted to the body (2). The valve (3) is mounted to the body (2) by means of the flange (9).
