Abstract
Abstract A fire-preventing fuel tank for motor vehicles and motor boats is disclosed, in which adjacent but separate volumes are provided in the tank, one kind of volumes holding the fuel, whereas the other holds a substance (e.g. a halogen), which, when admixed to the fuel, makes it non flammable. In the case of an accident, the shock ruptures the partition walls between the chambers holding the fuel and those holding the other fluid, so that fire is prevented. A number of different embodiments are described, but all of them realize the concept outlined above.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A self-extinguishing fire preventing fuel tank for vehicles that holds a combustible fuel and fluid fire extinguishing agent in a pre-selected ratio with the fuel, whereupon the occurrence of a condition capable of causing the fuel to ignite the tnak will insure an immediate and intimate admixture of the fire extinguishing agent and fuel so that the fuel will become a nonflammable mixture: a. a plurality of undulating elements stacked at different levels and each element having an undulating surface, wherein at each level the surfaces are perpendicularly arranged relative to each other; b. partition means formed between each level of the elements and are effective to form with the elements a plurality of alveoles at each level that is in fluid-tight relationship with an adjacent level; c. means for providing the fuel to the alveoles at alternate levels; and d. means for providing the fire extinguishing agent to the remaining levels of the stacked elements.
Claim 2
Dependent Claim
156 words
A self-extinguishing fire preventing fuel tank for vehicles that holds a combustible fuel and fluid fire extinguishing agent in a pre-selected ratio with the fuel, whereupon the occurrence of a condition capable of causing the fuel to ignite the tnak will insure an immediate and intimate admixture of the fire extinguishing agent and fuel so that the fuel will become a nonflammable mixture: a. a plurality of undulating elements stacked at different levels and each element having an undulating surface, wherein at each level the surfaces are perpendicularly arranged relative to each other; b. partition means formed between each level of the elements and are effective to form with the elements a plurality of alveoles at each level that is in fluid-tight relationship with an adjacent level; c. means for providing the fuel to the alveoles at alternate levels; and d. means for providing the fire extinguishing agent to the remaining levels of the stacked elements.
Claim 3
Dependent Claim
29 words
The fuel tank of claim 1 further comprising: means cooperating with the fuel and the fire-extinguishing agent so as to maintain the pre-selected ratio during consumption of the fuel.
Claim 4
Dependent Claim
61 words
The fuel tank of claim 2 wherein the cooperation means comprises: a. a first pump connected with a duct communicating with the alveoles containing the fuel; and b. a second pump connected to a duct communicating with the alveoles containing the fire-extinguishing agent, wherein both pumps are operatively ganged to each other so as to ensure the pre-selected ratio being maintained.
Claim 5
Dependent Claim
22 words
The fuel tank of claim 3 wherein the first pump is a delivery pump and the second pump is a discharge pump.
Claim 6
Dependent Claim
14 words
The fuel tank of claim 1 wherein the fire-extinguishing agent is a halogen type.
Claim 7
Dependent Claim
122 words
A self-extinguishing fuel tank for a combustible fuel comprising: a casing, a fuel inlet and a fuel outlet associated with said casing; means within said casing defining a large number of distinct fuel passages which extend from said inlet to said outlet and which are in communication with each other only at their opposite ends; means within said casing defining a large number of distinct second passages which are sealed from said fuel passages and which are in communication with each other only at their ends, and each of which is immediately adjacent one of said fuel passages, the interior of said casing being entirely filled with said passages; and inlet and outlet means for fire-extinguishing fluid associated with said second passages.
Claim 8
Dependent Claim
122 words
A self-extinguishing fuel tank for a combustible fuel comprising: a casing, a fuel inlet and a fuel outlet associated with said casing; means within said casing defining a large number of distinct fuel passages which extend from said inlet to said outlet and which are in communication with each other only at their opposite ends; means within said casing defining a large number of distinct second passages which are sealed from said fuel passages and which are in communication with each other only at their ends, and each of which is immediately adjacent one of said fuel passages, the interior of said casing being entirely filled with said passages; and inlet and outlet means for fire-extinguishing fluid associated with said second passages.
