摘要: A fuel dispensing nozzle is provided, the fuel dispenser comprising: a) a vapor recovery conduit effective to provide communication between a vapor space of a fuel tank to be refuelled and a system to remove vapors displaced by fuel added to the tank; b) a fuel supply conduit; c) a sealing device effective to mate in a sealing relationship with a fuel tank inlet; d) an optical liquid sensor within the vapor recovery conduit that is effective to generate a control signal when liquid is detected within the vapor recovery conduit; and e) a device to disenable fuel flow when a control signal is generated by the optical liquid sensor. Also, the fuel dispenser comprises a sealing device that comprises a device to determine if a sealing relationship exists between the fuel dispenser and the fuel tank inlet.
