摘要： According to the invention, there is provided a valve, and also dispensing or dosing apparatus (1) incorporating such a valve, for dispensing a predetermined dose of a first liquid into a second liquid, the apparatus comprising a sealed reservoir (10) for holding the first liquid, a reservoir outlet tube (24) connected to the reservoir at its in use upper region (18) and in fluid communication therewith, first valve means (30) for selectively dispensing a dose of the first liquid from the reservoir into the second liquid, and a dosing tube (26) between the reservoir outlet tube and the valve means. The apparatus is operable, when the reservoir holds the first liquid and on raising the level of the second liquid relative to the reservoir so as to subject the reservoir and first valve means to increased hydrostatic pressure, to discharge a dose of the first liquid into the dosing tube, via the reservoir outlet tube, and form a column of said first liquid that acts on the valve means, and subsequent lowering of the level of the second liquid relative to the apparatus so as to reduce the hydrostatic pressure acting on the reservoir and valve means causes the valve means to deliver the dose by opening of the valve means to allow dosing of the second liquid with the dose of the first liquid as the hydrostatic pressure acting on the valve means from the second liquid decreases below a predetermined amount,
