Claim:
1. A dispenser system comprising a storage vessel for storing a medium with at least one outlet valve, a refillable dispenser module with a medium chamber which can be filled with a medium, with a pumping apparatus which has an inlet channel and can be actuated for discharging the medium out of the medium chamber, and with at least one inlet valve, and an actuating apparatus, wherein the medium chamber is designed as a closed chamber with a variable volume, the dispenser module can be coupled to the storage vessel for filling the medium chamber, the at least one inlet valve and the at least one outlet valve being open in a forcibly actuated or pressure-loaded manner during filling, with the result that the medium chamber communicates with the storage vessel, the at least one inlet valve and the at least one outlet valve are closed in a disconnected state of the dispenser module and the storage vessel, and a volume of the medium chamber can be enlarged by means of the actuating apparatus during or after the coupling of the dispenser module and the storage vessel in order to generate a differential pressure between the medium chamber and the storage vessel, a pressure in the storage vessel being higher than in the medium chamber, in order to convey the medium out of the storage vessel into the medium chamber, wherein the actuating apparatus has at least one magnet and at least one at least partially magnetic or magnetizable element that interacts with the at least one magnet for a volume change of the medium chamber.
