Abstract

Disclosed is a system and method for delivering fuel to a plurality of vehicles. The system comprises a fuel source, a pump operable to draw fuel from the fuel source and a distribution manifold having a plurality of outlets. The system further comprises a plurality of fuel lines extending from the distribution manifold and a plurality of valve assemblies, each located in a tank of one of the plurality of vehicles each of the valve assembly being operable to independently shut off flow of fuel therethrough when the tank is filled to a predetermined level. The method comprises pumping the fuel supply from the fuel source to the distribution manifold, connecting a plurality of fuel lines to the distribution manifold and a valve assembly in each of a plurality of trucks in connection with one of the fuel lines.

Claims

1. A system for delivering fuel to a plurality of vehicles comprising:

a fuel source;

a pump operable to draw fuel from said fuel source;

a distribution manifold having a plurality of outlets, said distribution manifold in open fluidic communication with said pump;

a plurality of fuel lines, each of said plurality of fuel lines connected in free fluidic connection one of said outlets of said distribution manifold;

a plurality of mechanical valve assemblies, each located in a tank of one of said plurality of vehicles open fluidic communication with each of said plurality of fuel lines, each of said valve assembly being operable to independently shut off flow of fuel therethrough when said tank is filled to a predetermined level,

wherein each of said mechanical valve assemblies includes a biased piston slidably locatable within a housing and having a sealing face with an o-ring disposed thereon adapted to be sealed into contact with said housing when said tank is filled to said predetermined level, and

a control circuit programmed to turn said pump on and off at predetermined time intervals independent of said plurality of valve assemblies.

2. The system of claim 1 further comprising a pressure sensor in said distribution manifold.

3. The system of claim 2 wherein said control circuit is adapted to turn off said pump when said pressure sensor detects a pressure drop greater than a predetermined level.

4. The system of claim 1 wherein said piston includes a bore therethrough in fluidic communication with a float valve operable to be closed when said tank is filled to said predetermined level.

5. A method for delivering fuel to a plurality of vehicles comprising:

providing a fuel source containing a fuel supply;

pumping said fuel supply from said fuel source to a distribution manifold having a plurality of outlets, said distribution manifold in open fluidic communication with said pump;

connecting a plurality of fuel lines in free fluidic connection one of said outlets of said distribution manifold;

locating a mechanical valve assembly in each of a plurality of trucks wherein each of said mechanical valve assemblies includes a biased piston slidably locatable within a housing and having a sealing face with an o-ring disposed thereon adapted to be sealed into contact with said housing when said tank is filled to said predetermined level;

connecting each of said valve assemblies in open fluidic communication with each of said plurality of fuel lines, each of said valve assembly being operable to independently shut off flow of fuel therethrough when said tank is filled to a predetermined level; and

with a control circuit, turning said pump on and off at predetermined time intervals independent of said plurality of valve assemblies.

6. The method of claim 5 further comprising a pressure sensor in said distribution manifold.

7. The method of claim 6 wherein said control circuit is adapted to turn off said pump when said pressure sensor detects a pressure drop greater than a predetermined level.

8. The method of claim 5 wherein said piston includes a bore therethrough in fluidic communication with a float valve operable to be closed when said tank is filled to said predetermined level.
