Abstract: A device and related method for producing a ready-to-use solution from a concentrate and a diluent includes an inlet for the diluent; an inlet for the concentrate; an outlet for the solution; a line extending from the inlet for the diluent via a confluence where diluent and concentrate meet, to the outlet; a mixing container arranged in the line between the confluence and the outlet and having a larger cross-section than parts of the line, which are arranged upstream and downstream of the mixing container; and a metering pump for the concentrate, which is connected on the suction side to the inlet for the concentrate and on the pressure side to the confluence and which operates in a pulsed manner. The metering pump works with a clock frequency, in which a plurality of pump surges are attributable to the dwell time of the liquid in the mixing container.

Abstract: A metering device for metering additives into treatment liquids of a vehicle treatment installation includes an exchangeable storage container and a metering pump connected to the storage container, said metering pump metering an additive contained in the storage container into the treatment liquid. The metering device according to the invention comprises an integrated storage tank which communicates with the metering pump and with the storage container, thereby removing the need for a complete evacuation of the storage container and allowing the timely and easy exchange of a completely evacuated storage container without having to shut the vehicle treatment installation down to replace an evacuated storage container for a filled storage container.

Abstract: A supply container to be inserted in a holder of a metering device in a vehicle treatment facility includes a volume for liquid or viscous additives, and an outlet that can be connected to an inlet of the metering device when inserted into the holder. A holder for such a container includes a metering device inlet that can be sealingly connected to a closeable outlet in the supply container. The supply container can be easily inserted and securely retained in the holder. A supply container on which at least one guiding element is provided for engagement with at least one opposite guiding element on the holder when the supply container is inserted in the holder in a direction of insertion. A holder on which a guide is provided that includes at least one opposite guiding element for guiding at least one guiding element on the supply container when the supply container is inserted in the holder in a direction of insertion. A vehicle treatment facility can be provided with such a holder.
