Abstract

A fuel leakage vent is disclosed, wherein the fuel leakage vent is formed in a fuel source and valve interface to militate against an accumulation of fuel in a tank compartment.

Claims (32)

1. A fuel source and valve interface comprising:

a fuel source;

a main body of a valve in fluid communication with the fuel source; and

a fuel leakage vent formed in a wall of the fuel source to provide fluid communication between the fuel source and a desired fuel distribution area, wherein at least a portion of the fuel leakage vent is formed in the main body of the valve.

2. The interface according to claim 1 , wherein a pressure within the fuel source is higher than a pressure of the desired fuel distribution area.

3. A fuel source and valve interface comprising:

a fuel source;

a main body of a valve in fluid communication with the fuel source; and

a fuel leakage vent formed in a wall of the fuel source to provide fluid communication between the fuel source and a desired fuel distribution area, wherein the fuel source includes a female member that receives a corresponding male member of the main body of the valve.

4. A fuel source and valve interface comprising:

a fuel source;

a main body of a valve in fluid communication with the fuel source; and

a fuel leakage vent formed in a wall of the fuel source to provide fluid communication between the fuel source and a desired fuel distribution area, further comprising a first sealing structure disposed between the fuel source and the main body of the valve.

5. The interface according to claim 4 , further comprising a second sealing structure disposed between the fuel source and the main body of the valve.

6. The interface according to claim 5 , further comprising a first back-up sealing structure disposed adjacent the first sealing structure.

7. The interface according to claim 6 , further comprising a second back-up sealing structure disposed adjacent the second sealing structure.

8. A fuel source and valve interface comprising:

a hollow main body of a valve in fluid communication with a fuel source; and

a fuel leakage vent formed in the main body of the valve, the fuel leakage vent providing fluid communication between the fuel source and a desired fuel distribution area, wherein a pressure within the fuel source is higher than a pressure of the desired fuel distribution area;

a first sealing structure disposed between the fuel source and the main body of the valve; and

a first back-up sealing structure disposed adjacent the first sealing structure.

9. The interface according to claim 8 , wherein at least a portion of the fuel leakage vent is formed in a wall of the fuel source.

10. The interface according to claim 8 , further comprising a second sealing structure disposed between the fuel source and the main body of the valve.

11. The interface according to claim 10 , further comprising a second back-up ring disposed adjacent the second sealing structure.

12. A fuel source and valve interface comprising:

a high pressure storage vessel;

a main body of a valve in fluid communication with the high pressure storage vessel;

a fuel leakage vent formed in a wall of the high pressure storage vessel, the fuel leakage vent adapted to communicate with a desired fuel distribution area, wherein a pressure within the high pressure storage vessel is higher than a pressure of the desired fuel distribution area; and

a first sealing structure disposed between the high pressure storage vessel and the main body of the valve.

13. The interface according to claim 12 , wherein at least a portion of the fuel leakage vent is formed in the main body of the valve.

14. The interface according to claim 12 , further comprising a second sealing structure disposed between the high pressure storage vessel and the main body of the valve.

15. The interface according to claim 12 , further comprising a first back-up sealing structure disposed adjacent the first sealing structure and a second back-up sealing structure disposed adjacent the second sealing structure.
