Description

Non-powered fuel supply unit {A NON-POWER EQUIPMENT TO SUPPLY FUEL}

The present invention relates to a non-powered fuel supply apparatus, and more specifically, to form a fuel supply pipe for supplying fuel to the fuel tank higher than the height of the fuel tank, the fuel is introduced into the fuel tank by the potential energy, and pressurized A non-powered fuel supply device having a member and an elastic body and measuring the oil level of the fuel by a strain gauge, the manufacturing cost is reduced.

In general, a vehicle requires a fuel device for supplying a suitable mixer required by an engine, and the fuel device is an important device that determines performance, especially power and economy. Fuel filter to remove impurities, fuel pump to send fuel to carburetor, vaporizer to make a mixer and supply it to the engine, and fuel pipe connecting these devices It consists of.

Among the fuel devices configured as described above, the fuel tank has different capacities depending on the structure or use of the vehicle, but the fuel tank must be safely stored and carried in a traveling vehicle. Hereinafter, the fuel tank of the vehicle will be described.

FIG. 1 illustrates a fuel tank of a conventional vehicle, and includes a fuel inlet pipe 2 for inserting fuel into a tank body 1, which is a container for storing fuel, and a tank body on one side of the tank body 1. A fuel pump 3 that sucks fuel from (1) and feeds it into a carburetor to be delivered to the engine is connected to the fuel pump 3 so that the fuel injected through the fuel inlet 2 and stored in the tank body 1 is stored in the fuel pump 3. The engine was operated by supplying a mixer made by mixing the fuel and air in an appropriate ratio in the carburetor to each cylinder through an intake manifold.

As described above, the fuel stored in the fuel tank and the inside of the tank body 1 while the vehicle is slumped by the flow of the vehicle generates latent heat and static electricity in the fuel. Due to the static electricity, there is a problem that the fuel can be ignited and exploded at any moment.

In addition, the tank has a problem that it is impossible to quantitatively measure the residual fuel, since the oil level is changed due to the fluctuation of the fuel according to the driving conditions of the vehicle.

And, the fuel pump is attached separately, there is a problem that the structure of the fuel gauge and the warning light is complicated.

The present invention has been made to solve the problems as described above, by supplying the fuel supply to the fuel tank using the potential energy, and provided by the pressure member, the elastic body and the strain gauge, which is generated due to the flow of fuel It is an object of the present invention to provide a non-powered fuel supply device having an improved structure to prevent explosion of fuel due to static electricity and to simplify the structure to reduce manufacturing costs.

In the present invention, the elastic body is characterized in that the spring.

In the present invention, a sealing member for preventing fuel leakage is provided on the contact surface of the pressing member and the reservoir.

In the present invention, the sealing member is characterized in that the semi-circular.

Hereinafter, a terminal connection device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a cross-sectional view schematically showing a non-powered fuel supply apparatus according to a preferred embodiment of the present invention.

As shown in FIG. 2, the non-powered fuel supply device 100 includes a storage body 10, a fuel supply pipe 20 coupled to the storage body 10, a pressurizing member 30 that pressurizes the supplied fuel, and And an elastic body 40 for supporting the pressing member 30.

The storage body 10 refers to a member for storing the fuel 11. The storage body 10 is formed at the bottom thereof in a conical shape. The upper end of the storage body 10 is provided with a regulation jaw 13 to prevent the outflow of the stored fuel. A fuel inlet hole 15 through which fuel flows is formed at a lower end of the reservoir 10. The fuel supply pipe 20 is coupled to the fuel inlet hole 15.

The fuel supply pipe 20 is formed higher than the height of the storage body 10. Therefore, the fuel inflow from the fuel supply pipe 20 to the reservoir 10 is introduced by the force of the potential energy of the fuel 11. Therefore, the introduced fuel 11 flows into the storage body 10 through the backflow prevention member 21 installed at the lower end of the storage body 10. The backflow prevention member 21 is hinged to the fuel inlet hole 15 and is provided as a circular plate. The fuel 11 introduced into the reservoir 10 is pressed in the direction of gravity by the pressing member 30.

The pressing member 30 is formed in a conical shape that can be molded to the conical lower end of the storage body (10). The sealing member 31 is installed on the contact surface between the pressing member 30 and the storage body 10. The sealing member 31 prevents the outflow of fuel. The sealing member 31 is formed in a semicircular shape. The sealing member 31 is made of a material having rubber elasticity and viscosity to maintain the airtight enough to prevent the outflow of the fuel (11). Therefore, the sealing member 31 allows the pressing member 30 to move up and down smoothly between the inner walls of the storage body 10 without distortion. At a predetermined position of the pressing member 30, a strain gauge 35 connected to a vehicle instrument panel (not shown) and a wire 33 is installed. The lower end of the pressing member 30 is provided with an elastic body 40.

The elastic body 40 is installed between the pressing member 30 and the storage body 10 to impart a predetermined elastic force to the pressing member 30. The elastic body 30 is preferably provided with a spring. The spring force of the elastic body 30, the self-gravity of the pressing member 30, and the buoyancy of the fuel 11 has a structure having an equilibrium relationship. When the fuel is supplied from the reservoir 10 and exits, the elastic body 40 is contracted by the weight of the pressing member 30. Therefore, the fuel stored in the storage body 10 has a structure that is supplied by the non-power.

The present invention has been described above with reference to the embodiments shown in the drawings. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope equivalent to the present invention are possible by those skilled in the art.
