Patent ID: 7591291

Claim:
A liquid fuel storage reservoir assembly comprising: an enclosed tank having a threaded coupling sealably installed at or near the bottom thereof, said coupling having an opening in communication with a fillable interior volume of the tank; a quantity of fuel at least partially filling said tank; a fuel receiver and check valve assembly having: a check valve body having a flow-through chamber, an entrance end, and an exit end threaded to engage the threaded coupling; a spring-loaded, normally-closed valve that blocks said flow-through chamber when closed, thereby being subjected to gravity-generated pressure from said quantity of fuel, and that opens said flow-through chamber during tank filling operations; a fuel receiver body having a generally tubular chamber, said generally tubular chamber having an entrance end that is coupleable to a fuel nozzle, and an exit end that is coupleable to the entrance end of said check valve body; and a spring-biased valve plug that seals the entrance end of said generally tubular chamber except during tank filling operations.
