Fuel nozzle

摘要

Disclosed is a filling nozzle for dispensing a liquid such as urea solution into a tank (16) of a motor vehicle. The filling nozzle includes safety means to ensure that the filling nozzle delivers the correct fuel to a vehicle fuel tank. The filling nozzle includes a main valve (5). A safety valve (7) is arranged downstream from the main valve (5). The safety valve (7) can be moved from a closed position to an open position by means of an opening movement directed in the upstream direction. A safety device (11) comprising a sliding sleeve has an operative connection with the safety valve (7). The operative connection between the safety device (11) and safety valve (7) is realised magnetically (10, 13). The safety device (11) is also designed to detect the insertion of the filling nozzle into a tank (16) provided for the corresponding liquid. The safety device (11) effects the movement of the safety valve (7) from the closed position into the open position when the filling nozzle is inserted into a tank (16) for the corresponding liquid.
