ABSTRACT:
A fuel dispensing nozzle for a closed system holding a volatile fuel. The nozzle is adapted to sealably engage the filler pipe of a fuel tank to avoid passage of fumes to the atmosphere during a fuel transfer operation. The nozzle will automatically discontinue fuel flow in response to a reduction in flow rate within the closed system, which would otherwise cause recycling of fuel through the nozzle and back to its source.
