Abstract

Within a vehicle fuel tank the fuel is contained in a flexible bag. The fuel is introduced through a sealing filler cap and is withdrawn by a pump through a feed line. A safety valve may be included in the feed line, closing if the line becomes disconnected. The bag avoids fuel vapours in the tank and contributes to vehicle safety.

Description

SAFETY VACUUM TANK I'd like to introduce you to a new system for the safety, conservation, and use of fuel in all kinds of cars and airplanes. The system is very simple and can be adapted to any type of petrol tank. This system works under the laws of vacuum and suction.

To create such a system we need to have a flexible petrol tank which fits inside of todays common-used petrol tanks (of all makes). By adopting this system, we hope to reduce the dangers of fire and explosion in both cars and airplanes during accidents. When a car turns over or an airplane crashes, it's usually the fuel leakage which causes an explosion.

This system should reduce, if not terminate the risk of fuel splashes.

It is also economically and ecologically beneficial because this system brings the fuel evaporation to a minimum.

The "flexi-tank" should be made of a non-flammable, strong, resistant, flexible material (perhaps plastic , rubber,..etc.) The flexi-tank extends itself from the petrol cap at the top to the pump at the rear of the original petrol tank, preferably in one piece. The shape of the flex-tank can vary, depending on the shape or design of the original petrol tank, which would become a sort of protection cover for the flexi-tank. The petrol cap should make an absolute closure and be operated by a relief valve, so when the petrol cap is firmly closed there is no way air or fuel can pass by; so the relief valve is used to open the petrol cap.

Once the tank is filled, and as soon as the pump starts the vacuum and suction will begin to function. Naturally, as the fuel is consumed our flexi-tank gets smaller and smaller disallowing the continuous evaporation of fuel, caused by the fuel movement in our present tanks. There probably won't be any odours of fuel inside cars because evaporation (which sends this odour into cars) will be eliminated.

If there are any accidents, we have the guarantee that there won't be any petrol splashes out of the flexi-tank. These petrol splashes are, of course, the major causes of fires and/or explosions during accidents which lead to a great loss of lives, whether in care or air planes.

If you take a look at the drawing, you'll notice that the petrol is sucked out or vacuumed at the top of the flexi-tank which will permit the flexi-tank to always keep in harmony with the amount of petrol kept in the flexi-tank. In other words, according to the law of vacuum or suction, the flexi-tank diminishes in size to allow only enough room for the amount of petrol left in the flexi-tank.

The flexi-tank can be made in any shape or size and generally any type of highlyflammable powered engines. For example, if a flexi-tank is designed for the capacity of 60 liters, the flexi-tank should be capable to withstand 60 liters freely and easily, plus have the ability to decrease in size during the consumption of fuel, - like a deflated football. (On option, a safety valve can be used on the feeding line from the flexi-tank towards the pump, so if the feeding line disconnects from the pump, the valve will keep the petrol securely inside the flexi-tank not allowing it to leak.) The feeding line, which starts at the mid-top of the flexi-tank and leads to the pump, should not be as flexible as the flexi-tank itself; it should be made with a tougher, harder material. This way the feeding line will allow the fuel to be pumped freely with no blockages.

Since the flexi-tank is vapor free, it could help us to have a cleaner environment; and economically help us to conserve fuel better than with the present petrol tank. Imagine if we can save at least a liter of fuel in each car every week, which now evaporates into the air. As you see, it is a considerable amount of fuel that just fades into the air and causes pollution. I believe this system will reduce the consumption of fuel because we now calculate the evaporation as a consumption! This system will probably have other benefits as well, which time will show.

I,Ali Reza Teimourian, date of birth 05.05.61, claim that this "Safety Vacuum Tank" benefits from the law of vacuum has been designed by myself.

I reserve all the rights on the product and marketting of the "Safety Vacuum Tank".

Claims

Claim 1 - Safety Vacuum Tank (or Flexi-Tank)

S.V.T. - Safety Vacuum Tank isa flexible tank made with a material which can be made in any shape depending on its' hard covering.

It benefits from the law of vacuum and suction for fuels in a closed up space (fuel tank).

The "Flexi-Tank" can be made from any type of material as long as it resists petrol or other fuels, and retains the capability of being flexible.

The "Flexi-Tank" can be made with rubber or plastic coated materials, etc,... which must also be non-flammable.
