摘要

The invention relates to a metering device for metering additives into treatment liquids of a vehicle treatment installation, comprising an exchangeable storage container (1) and a metering pump (2) connected to the storage container, said metering pump metering an additive (3) contained in the storage container (1) into the treatment liquid. The metering device according to the invention comprises an integrated storage tank (5) which communicates with the metering pump (2) and with the storage container (1), 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.
