ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a novel fuel valve for use in connection with the fueling of hobby equipment such as gas powered airplanes, cars, boats and other equipment.
SUMMARY OF THE INVENTION
In order to fuel hobby type gas powered equipment, it is typically required to pump fuel from a plastic container containing premixed fuel through a hand pump to the equipment. Fuel valves are often used to connect the necessary hoses and other equipment. Typically, current fuel valve systems require that two holes or openings be made in the container. A first hole is made in the cap of the fuel container to connect the fuel intake and feed lines to the pump and fuel nozzle. A second hole is also made to provide a vent hole and to accommodate a nozzle seal.
The present invention improves upon the prior art by the use of a novel fuel valve system which requires the creation of a single hole in the cap. The invention includes a base in which two passageways are located. One passageway serves as a complete fuel line and the second serves as both a vent and nozzle retention port.
