ABSTRACT:
Fuel vapors displaced from a vehicle's fuel tank during refueling are recovered by a system employing a liquid jet pump to produce a suction. A minor portion of a conventional fuel pump's output is diverted from the usual metering-and-dispensing conduits, passed through the jet pump, and then recycled to the fuel reservoir which supplies the fuel pump. The familiar fuel dispensing nozzle is provided with passages for conveying vapors away from the vehicle fuel tank. A vapor conduit links those passages with the jet pump thereby aspirating the displaced vapors to the jet pump and, ultimately, the fuel reservoir. Valving arrangements in the nozzle's vapor passages are suited for use with various vapor recovery systems, as is a mechanism which automatically interrupts the dispensing of fuel when there arises a danger of either fuel or vapor escaping from the vehicle's tank.
