Description
/ 7 “HYDRAULIC ADAPTER DEVICE FOR FUEL SUPPLY SYSTEM” Field of Invention
[0001] The present invention relates to a hydraulic adapter device for a fuel supply system, with application for use with ethanol, gasoline or diesel, which provides an interface for two different types of connecting pipes or hoses with different diameters, enabling the use of different standards and brands, thus facilitating the repair and retrofit of systems. Fundamentals of the Invention
[0002] As is known, the fuel module is an essential component in vehicles with electronic fuel injection. It is responsible for storing, pumping, filtering, and regulating the pressure of the fuel before delivering it to the engine.
[0003] The module consists of a reservoir connected to the vehicle's fuel tank that is designed to store and maintain a reserve available for the engine. Inside it is a pump that is responsible for pumping fuel from the reservoir to the engine, which is electrically driven and is designed to provide the necessary pressure to ensure that the fuel is delivered efficiently to the engine.
[0004] Additionally, the fuel module also contains a filter that removes impurities and particles, helping to ensure that the fuel is clean and free of contaminants that could impair engine performance, as well as the possibility of having a pressure regulator that controls the fuel pressure. This is important to ensure that the correct quality and quantity of fuel is supplied to the engine, according to the vehicle's operating demands.
[0005] In this system, hoses (or connecting pipes) play a crucial role in transporting the fuel, being made of strong and durable materials, designed to withstand the pressure and temperature of the fuel, allowing the fuel to flow efficiently and safely. Petition 870240109214, dated 12 / 20 / 2024, page 7 / 17 / 7
[0006] Among the system components, different manufacturers may use different diameters of interconnecting hoses, meaning that the components cannot be easily interchanged if different brands are chosen.
[0007] Patent document US1104480349 describes a device that can securely connect hoses or other equipment together, creating a tight seal, with pin-shaped (serrated) connections of various diameters that can be inserted into a flexible hose, being screwed into a female connection with a separating edge. This device does not take into account the internal fluid flow, in the case of a very small diameter with a larger diameter outlet (which would cause high pressure), nor does it consider a construction that demands more safety and robustness.
[0008] Based on this scenario, and aiming to mitigate the observed technical limitations, the present invention arises. Objectives of the Invention
[0009] Thus, the main objective of the present invention is to disclose a hydraulic adapter device for a fuel supply system that provides an interface for two different types of connecting pipes or hoses with different diameters, providing better versatility.
[0010] Additionally, the present invention aims to provide a hydraulic adapter device for a fuel supply system, enabling the repair and / or adaptation of different systems and brands, and allowing the use of two types of pipe or hose diameters, as well as use with different types of fuels.
[0011] Furthermore, the present invention aims to disclose a hydraulic adapter device for a fuel supply system that has a stop that limits the end of the pipe stroke, in addition to providing better mechanical resistance in the part and assembly.
[0012] Furthermore, the objective of the present invention is to present a hydraulic adapter device for a fuel supply system that, based on a continuous internal diameter and construction, enables pressure stabilization in Petition 870240109214, dated 12 / 20 / 2024, page 8 / 17 / 7 system.

[0014] According to the fundamental premises of the invention in question, the hydraulic adapter device for the fuel supply system also includes the fact that the part is composed of a polymeric material.
[0015] Additionally, a hydraulic adapter device for the fuel supply system is provided, comprising the fact that the part is made of a polyoxymethylene (POM) material.
[0016] Furthermore, the present invention proposes a hydraulic adapter device for a fuel supply system comprising the fact that one of the smaller diameter serrated fittings for creating a seal with a hose on the first side is up to 3 / 4 of the diameter of the larger diameter fitting.
[0017] Furthermore, according to the present invention, the hydraulic adapter device for a fuel supply system comprises the fact that the serrated fitting on the first side for creating a seal with a smaller diameter hose is up to 4.8 mm in diameter, and the serrated fitting on the first side for creating a seal with a larger diameter hose is up to 6 mm.
[0018] Additionally, in the present invention, the hydraulic adapter device for the fuel supply system comprises the fact that the fitting Petition 870240109214, dated 12 / 20 / 2024, page 9 / 17 / 7 serrated edge on the second side to create a seal with a hose up to 6mm in diameter.
[0019] Also, according to the present invention, the hydraulic adapter device for the fuel supply system comprises the fact that the stop has a length of at least 6 mm.
[0020] In the proposed invention, the hydraulic adapter device for the fuel supply system also comprises the fact that the device has at least one sealing ring or gasket that is sized for the distance between the serrations of the fittings.
[0021] Finally, the present invention includes a hydraulic adapter device for a fuel supply system comprised in that the serration has a height of 0.5 mm from the body of the connector. Brief Description of the Figures
[0022] The preferred embodiment of the invention in question is described in detail based on the listed figures, which:
[0023] Figure 1 illustrates the hydraulic adapter device for the fuel supply system.
[0024] Figure 2 illustrates, in cross-section, the hydraulic adapter device of the fuel supply system. Detailed Description of the Invention
[0025] According to the general objectives of the invention in question, the hydraulic adapter device for a fuel supply system comprising: a piece composed of at least one first side a and at least one second side b, at least one stop c, also comprising the fact that the piece is formed of a single part where a first side a has at least two serrated fittings of different diameters configured to create a seal with at least one hose and a second side b with at least one serrated fitting to create a seal with at least one hose, with the sides separated by the stop c, having a continuous internal channel of diameter d, compatible with the smaller diameter fitting of the first side a. Petition 870240109214, dated 12 / 20 / 2024, page 10 / 17 / 7
[0026] Additionally, the hydraulic adapter device for the fuel supply system comprises the fact that the part is composed of a polymeric material. Thus, the device is formed by a single piece, where the polymer can be any plastic material that possesses physical resistance in addition to being resistant to fuels such as gasoline, ethanol, or diesel, which can be, for example, polyethylene, polypropylene, PVC, among others.
[0027] Furthermore, the hydraulic adapter device for the fuel supply system also includes the fact that the part is made of a polyoxymethylene (POM) material. Also known as polyacetal or acetal, POM is a thermoplastic polymer that has high mechanical and chemical resistance, as well as rigidity and dimensional stability, and is frequently used in the manufacture of valve parts and components that require high precision and wear resistance, thus being recommended for application with different fuels.
[0028] Furthermore, the hydraulic adapter device for the fuel supply system comprises the fact that on the first side a, the smaller diameter fitting a2 is up to 3 / 4 the size of the larger diameter fitting a1. Similarly, in the hydraulic adapter device for the fuel supply system, the serrated fitting on the second side b for creating a seal with a hose has a diameter fitting b1 equal to the diameter fitting a1.
[0029] Additionally, the hydraulic adapter device for the fuel supply system comprises the fact that on the first side a, the smaller diameter fitting a2 is up to 4.8 mm and the larger diameter fitting a1 is up to 6 mm. Thus, the serrated fitting on the second side b, for creating a seal with a hose, has a fitting diameter b1 equal to the fitting diameter a1, up to 6 mm.
[0030] Furthermore, the hydraulic adapter device for the fuel supply system comprises the fact that the stop c has a length of at least 6mm. In this way, its size matches the larger fitting diameter, providing a support surface for the system, as well as becoming an end barrier for the hoses. Petition 870240109214, dated 12 / 20 / 2024, page 11 / 17 / 7
[0031] Figure 1 illustrates the hydraulic adapter device for a fuel supply system, composed of side bea, where the diameter fitting b1 is equal to the larger diameter fitting a1, and also has the smaller diameter fitting a2. The length of the stop c is also illustrated, as well as the height of the serrations h. Figure 2 illustrates in cross-section the hydraulic adapter device for a fuel supply system, with a continuous internal diameter d compatible with the smaller diameter fitting a2, as well as the height of the serrations h and the length of the stop c.
[0032] Thus, the hydraulic adapter device for the fuel supply system comprises the fact that the serration has a height h of 0.5mm from the connector body. In this way, the height facilitates the manual assembly of the hoses in the device, thus ensuring that excessive force is not required, in addition to the seal being aided by at least one sealing ring or gasket.
[0033] Additionally, the hydraulic adapter device for the fuel supply system also includes the fact that at least one sealing ring or gasket is sized to fit within the gap between the serrations of each fitting, thus providing greater safety to the system.
[0034] The proposed device comprises a component that is applied to the fuel supply module, whether for retrofit or repair of fuel pumps, being applied in systems that operate with ethanol, gasoline or diesel. It provides assembly between two hoses (or tubes) of different diameters or of the same diameter, whether of the same brand or not, thus optimizing the use of a single piece for two different standards, reducing costs in the production of specific devices for each size. The diameters of the fittings can be applicable to any diameter or standard.
[0035] It is important to emphasize that the description above has the sole purpose of illustrating, in an exemplary manner, the particular embodiment of the invention in question. Therefore, it becomes clear that modifications, variations, and constructive combinations of the elements that perform the same function substantially as the Petition 870240109214, dated 12 / 20 / 2024, page 12 / 17 / 7 same form to achieve the same results, remain within the scope of protection delimited by the attached claims.
