An apparatus for drawing a pre-selectable quantity of liquid, in particular a quantity of water, comprises an input device, at which the respectively desired quantity of liquid to be delivered automatically can be fed in. Located in the path of the liquid is an electrically variable flow-control valve, whereof the position is varied automatically according to the pre-selected quantity of liquid, corresponding to a characteristic curve stored in a memory: the flow rate is chosen to be all the greater, the greater the pre-selected quantity of liquid. Due to this it is ensured that very different quantities of liquid can be drawn in times which are practical for use.
