Abstract A nozzle for filling up with fuel by means of a fuel pump, with a nozzle housing, which on the one hand has a fuel dispensing pipe and on the other hand a pump hose connection, with a device for extracting fuel vapours, which includes a gas valve which can be connected to a vacuum source via a gas hose and which is inserted into the nozzle housing and has fuel flowing round it whenever fuel is flowing, the gas valve having a gas valve body co-operating with a valve seat, the gas valve body being connected to an operating magnet, which is mounted in a non-ferromagnetic operating magnet housing and is displaceable so as to open and close the gas valve, and with an actuating magnet mounted outside the operating magnet housing and displaceable between an initial position and a final position defined by a stop, the actuating magnet being coupled magnetically to the operating magnet, wherein, outside the operating magnet housing, a suspension unit is displaceably mounted which, when fuel flows, is subjected to pressure by the fuel and can in this way be moved from an initial position against the action of a restoring spring, the suspension unit being provided with a suspension unit magnet and being capable of being coupled magnetically to the actuating magnet, and wherein the operating magnet constantly opens and closes the gas valve depending on its displacement.
