摘要

A housing (6a) has a liquid flow path connecting an inlet (2) and an outlet (4) through which the liquid flows. The diluted viscous concentrate contained in the storage space of holder linking with housing inlet, is dispensed in a metered manner. A gear pump (8) in the liquid flow path is driven by a rotor (16) by the magnetic field change. Independent claims are also included for the following: (a) Dilute concentrate filled holder; (b) Beverage preparing apparatus
