Claims

1. An adapter for automatically fueling automotive vehicles, primarily cars, wherein a robot which includes a robot head that is movable in relation to the robot and can be brought to a predetermined position in relation to the fueling-tank pipe of the vehicle by means of a positioning system and therewith docked with said adapter (3), wherein the adapter is intended to be fastened to the upper orifice of the fuel-tank pipe (2) and includes a conical part, and wherein the robot head includes a tube whose free forward end is intended to extend to a position down in the fuel-tank pipe when docking is completed, whereafter fuel is delivered through said tube, characterized in that the adapter (3) includes a base part (13) and an adaptation funnel (14), wherein the base part (13) is intended to be fastened to the fuel-tank pipe (2) in coaction with fastener means (15) provided on said pipe, and wherein the base part has an opening (16); in that the adaptation funnel (14) projects out from the base part (13); and in that the adaptation funnel (14) is rotatable relative to the base part about the longitudinal axis (17) of said base part, thereby enabling the adapter (3) to be positioned correctly on the fuel-tank pipe (2) in a rotational direction.
  2. An arrangement according to Claim 1, characterized in that the adaptation funnel (14) is constructed so that the plane of the bottom orifice (19) of the funnel located at the orifice of the fuel-tank pipe (2) defines an angle with the plane of its upper orifice (18) at which docking takes place.
  3. An arrangement according to Claim 1 or Claim 2, characterized in that the adaptation funnel (14) can only be rotated in relation to the base part (13) in the same direction as the base part is rotated when screwing said base part onto the threads (15) of the fuel-tank pipe (2).
  4. An arrangement according to Claim 1, 2 or 3, characterized in that the upper part of the base part (13) includes a toothed ring (20) which faces inwardly of the base part and which coacts with a plate (21) provided with one or more radially extending, resilient hooks (23-26) which engage said toothed ring; in that the adaptation funnel (14) is rotatably attached to the base part (13) but in non-rotational engagement with the plate (21); and in that the teeth and the hooks are configured so that the adaptation funnel (14) can only be rotated relative to the base part (13) in the same direction as that in which the base part is rotated as it is screwed onto the threads of the fuel-tank pipe.
  5. An arrangement according to Claim 1, 2, 3 or 4, characterized in that the adaptation funnel (14) is removably mounted on the base part (13).
  6. An arrangement according to Claim 1, 2, 3, 4 or 5, characterized in that the base part (13) is constructed so as to extend down into the fuel-tank pipe (2); in that a pivotal cover (38) of known kind is pivotally mounted in that part of the base part (13) which is located below the orifice of the fuel-tank pipe when said base part is fitted on said pipe (2), wherein said cover is swung to one side against the action of a spring as the robot-carried tube is moved down through the adapter (3) and into the fuel-tank pipe.
  7. An arrangement according to Claim 1, 2, 3, 4, 5 or 6, characterized in that when fitted to the fuel-tank pipe (2) the base part (13) is located completely below the orifice of the fuel-tank pipe, with the exception of a radially and outwardly projecting collar (34) immediately above the orifice of said pipe (2).
  8. An arrangement according to Claim 7, characterized in that the adaptation funnel (14) is fastened to the periphery of the collar (34).
