Abstract
A device for robotizable refuelling of a vehicle includes a docking component which can be installed on a filling tube of a fuel tank of the vehicle for receiving a pistol nozzle, in which the pistol nozzle can be locked, in axial and peripheral directions, and which has a central passage for a fill pipe of the pistol nozzle. The device contains a hollow cylindrical ring carrier element provided with a central passage fastened on an underside of the docking element. A locking ring provided with radially projecting bayonet arms is held against torsion but axially moveable on the ring carrier element. A compression spring is braced between the underside of the locking ring on the one hand and a connection of the ring carrier element. The device can be installed on the edge of the filling tube, which is provided with recesses for passage of bayonet arms of the locking ring at an inlet side to form a bayonet lock. In order to make secure refuelling possible in a simple manner, the ring carrier element carries a coupling ring arranged torsion fast on the filling tube lying on top of the locking ring. Stop structures corresponding to each other are defined on an upper side of the coupling ring and on the underside of the docking element so that the docking element can be fixed on the coupling ring.
