  • Vapor-liquid separator for evaporative emissions control system
    Patent number: 5103877
    Abstract: A tank vapor vent valve for a vehicle on board fuel emissions vapor recovery system has a liquid-vapor separator integrated into its design. A blocking valve is held closed when the tank is not being filled, but springs open when the nozzle is inserted to fill the tank, allowing venting flow out of the tank. A cup suspended below the valve catches entrained liquid fuel to keep it out of the canister line, and pulls the blocking valve shut when full. When the nozzle is removed, a drain plug at the bottom of the cup is automatically pushed open.
