ABSTRACT:
An in-line fuel fill valve assembly which provides for rapid and efficient refueling of compressed natural gas powered vehicles is provided and includes a receptacle adapted to mate with a fuel supply nozzle and a valve body having an in-line gas flow passage therethrough. The gas flow passage has first and second ends, with the first end communicating with the receptacle, and the second end terminating at an outlet which is adapted to communicate with a fuel storage vessel. A check valve is positioned in the gas flow passage of the valve body and is normally biased into a closed position to prevent the flow of gas through the first gas flow passage, but which opens in response to a flow of fuel under pressure.
