Patent ID: 6974052

Claim:
A dosing device removably located in a dispensing machine which dispensing machine comprises a magnetization unit for generating a changing magnetic field, said dosing device comprising a housing comprising at least one inlet, at least one outlet, a liquid flow path extending from the inlet to the outlet, and a pump included in the liquid flow path, the dosing device being adapted for dispensing in a metered manner a viscous concentrate from a holder in which the concentrate is contained, the concentrate in diluted form giving a product suitable for consumption, the holder comprising a storage space in which the concentrate is contained, and the inlet of the dosing device being adapted to be connected, in use, to the storage space of the holder, wherein the dosing device comprises a rotor rotatably connected to the housing for rotation around a rotation axis, for causing the rotor to rotate about the rotation axis in response to the changing magnetic field of said magnetization unit, the pump being mechanically connected to the rotor for driving the pump in response to the rotation of the rotor by changing the magnetic field.
