Patent ID: 7353807

Claim:
A liquid fuel system for a fuel injected combustion engine comprising: a fuel reservoir configured to be disposed in a fuel tank; a fuel pump having an inlet communicating with the reservoir and at least one fuel outlet configured for supplying fuel to the combustion engine; an electric motor connected to the fuel pump for operating the fuel pump; a jet pump assembly for transferring fuel from the fuel tank into the reservoir; an in-line pressure poppet valve assembly interposed between the fuel outlet and the jet pump assembly, yieldably biased toward a closed position and when closed preventing supplemental fuel flow to the jet pump assembly during impaired fuel pump operation, and the in-line poppet valve assembly having a housing having a fuel inlet, an annular seat downstream of the fuel inlet, an annular flow chamber downstream of the seat and tapering outwardly downstream of the seat; and a valve having an enlarged head engageable with the annular seat to close the valve assembly, received in the annular flow chamber, tapered outwardly downstream of the annular seat, and when moved to an open position is disengaged from the seat so that fuel flows around the head, through the flow chamber and into the jet pump assembly for transferring fuel from the fuel tank into the reservoir.
