Filler pipe for motor vehicle

Abstract

The invention provides a special filler pipe for a motor vehicle, solving the technical problem that when a oiling gun is inserted into a funnel neck to oil a fuel tank, the delay phenomenon is generated when the fuel oil penetrates through a first bending portion such as a corrugated pipe, and the fuel oil can not smoothly flow into the fuel tank. The invention is characterized in that a guard ring is arranged in the funnel neck, the funnel neck, a filter and a petroleum pipeline are connected in order, wherein the funnel neck and the filter, the filter and the petroleum pipeline are connected by a convex-concave structure, the petroleum pipeline is corrugated. The invention has the beneficial effect that no any resistance is generated in the filter and the petroleum pipeline in oiling, and the fuel is added to the fuel tank quickly.

Description

technical field [0001] The invention relates to a special fuel filler pipe for motor vehicles, in particular to a special fuel filler pipe for vehicles that can smoothly refuel motor vehicles. Background technique [0002] Refueling pipes are generally used for refueling motor vehicles. The filling pipe is generally composed of a funnel neck and a fuel delivery pipe. The funnel neck, the fuel delivery pipe and the fuel tank are connected in sequence, and the fueling gun is inserted into the funnel neck to add fuel to the fuel tank. [0003] The above-mentioned oil delivery pipe is fixed along the bottom of the vehicle. In order to make the oil delivery pipe more tightly fixed on the curved part of the vehicle, most of the oil delivery pipes fixed on the curved part of the vehicle are in the form of bellows, so as to be more firmly and tightly fixed on the vehicle. bottom of. But there is following shortcoming in the oil pipeline similar to above-mentioned bellows shape: ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the fuel gun is inserted into the funnel neck for refueling, the fuel will be delayed when it passes through the bellows of the first bending part, and it cannot flow into the fuel tank smoothly;

[0005] 2. Due to the above-mentioned delay, when a large amount of fuel is injected into the refueling gun, the resulting delay cannot be refueled smoothly, which makes refueling consume more time;

[0006] 3. The bending parts of different models are different, and corresponding corrugations are required on the fuel pipe to correspond to it. In this way, the cost of manufacturing a fuel pipe suitable for most vehicles will increase accordingly
