Abstract
Abstract A fuel feeding system for a vehicle wherein a conventional spare tire and wheel assembly is used as an accumulator, supply tank and/or reservoir for a pneumatic pressure fluid, such as air, to supply liquid fuel from a tank to an engine, preferably in a wheeled vehicle; and novel means are provided for ducting vapors to the engine and preventing the same from escaping from the tank and polluting the atmosphere.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
In a vehicle, engine means, liquid fuel tank means connected to said engine means for supplying liquid fuel thereto, accumulator means connected to said liquid fuel tank means, said accumulator means having pressure fluid means therein for forcing liquid fuel from said liquid fuel tank means to said engine means, compressor means connected to said accumulator means and said liquid fuel tank means for supplying pressure fluid thereto, emergency pressure fluid cylinder means connected to said fuel tank means, and two-way valve means connected in such a manner as to permit the flow of pressure fluid to said fuel tank means when the flow of pressure fluid from said compressor means and said accumulator means has been cut off.
Claim 2
Dependent Claim
119 words
In a vehicle, engine means, liquid fuel tank means connected to said engine means for supplying liquid fuel thereto, accumulator means connected to said liquid fuel tank means, said accumulator means having pressure fluid means therein for forcing liquid fuel from said liquid fuel tank means to said engine means, compressor means connected to said accumulator means and said liquid fuel tank means for supplying pressure fluid thereto, emergency pressure fluid cylinder means connected to said fuel tank means, and two-way valve means connected in such a manner as to permit the flow of pressure fluid to said fuel tank means when the flow of pressure fluid from said compressor means and said accumulator means has been cut off.
Claim 3
Dependent Claim
20 words
In a vehicle as set forth in claim 1, wherein said accumulator means comprises spare tire and wheel assembly means.
Claim 4
Dependent Claim
23 words
In a vehicle as set forth in claim 1, pressure regulator means controlling the flow of pressure fluid to said fuel tank means.
Claim 5
Dependent Claim
22 words
In a vehicle as set forth in claim 1, valve means controlling the flow of pressure fluid to said fuel tank means.
Claim 6
Dependent Claim
62 words
In a vehicle as set forth in claim 1, solenoid-operated valve means operated by an engine ignition switch controlling the flow of pressure fluid to said fuel tank means and cutting off the flow of pressure fluid when said engine ignition switch has been turned off, and opening the flow of pressure fluid when said engine ignition switch has been turned on.
Claim 7
Dependent Claim
35 words
In a vehicle as set forth in claim 1, wherein said emergency pressure fluid cylinder means contains pressure fluid that supports the combustion of the liquid fuel with oxygen and does not suppress said combustion.
Claim 8
Dependent Claim
142 words
In a wheeled vehicle, engine means for propelling the vehicle, liquid fuel tank means connected to said engine means for supplying liquid fuel to the same, spare tire and wheel assembly means of the vehicle functioning as an accumulator, air compressor means driven by said engine means and supplying compressed air tO said spare tire and wheel assembly means and to said liquid fuel tank means for forcing liquid fuel therefrom to said engine means, pressure regulator means controlling the flow of compressed air to said liquid fuel tank means, and solenoid-operated valve means operated by an engine ignition switch for shutting off the flow of compressed air to said liquid fuel tank means when said ignition switch is turned off, and for opening the flow of compressed air to said liquid fuel tank means when said ignition switch is turned on.
Claim 9
Dependent Claim
142 words
In a wheeled vehicle, engine means for propelling the vehicle, liquid fuel tank means connected to said engine means for supplying liquid fuel to the same, spare tire and wheel assembly means of the vehicle functioning as an accumulator, air compressor means driven by said engine means and supplying compressed air tO said spare tire and wheel assembly means and to said liquid fuel tank means for forcing liquid fuel therefrom to said engine means, pressure regulator means controlling the flow of compressed air to said liquid fuel tank means, and solenoid-operated valve means operated by an engine ignition switch for shutting off the flow of compressed air to said liquid fuel tank means when said ignition switch is turned off, and for opening the flow of compressed air to said liquid fuel tank means when said ignition switch is turned on.
Claim 10
Dependent Claim
73 words
In a wheeled vehicle as set forth in claim 7, emergency cylinder means containing a pressure fluid connected to said liquid fuel tank means, and two-way valve means for disconnecting the flow of compressed air to said liquid fuel tank means, and for releasing the pressure fluid of said emergency cylinder means to said liquid fuel tank means when the flow of compressed air has been shut off by said two-way valve means.
Claim 11
Dependent Claim
85 words
