The device comprises a water supply at constant pressure, a container for a concentrated liquid, from which the concentrated liquid is emptied via a line (22), and an entry of this line (22) into the water supply. Furthermore, an emptying line leading to a container is provided for the mixture. At its upstream end, i.e. in the region in which the water supply and the line (22) converge, the container has a Venturi nozzle (24, 25).
<??>According to the invention, a chamber (20) is provided, in which the water supply opens out axially with interposition of an injection nozzle (19), and into which, furthermore, the emptying line of the mixture opens out axially, specifically via the upstream end of the Venturi nozzle (24, 25). An annular space (26) is formed between the Venturi nozzle (24, 25) and the chamber wall, while the liquid feed line (22) for the concentrated liquid opens out radially into the chamber (20).
<??>The device is particularly suitable for dispensing coffee.
