A drink dispenser includes a body of a head of the device having a cavity that defines a three-way passageway, the cavity containing a tubular element which is slidably movable along an axial direction of the tubular element between a first and second end run position. The tubular element includes a lateral wall that is placed against the first passageway so that the drink can flow from the second passageway into a third passageway. The tubular element is mechanically interconnected by rack-and-pinion links contained in the body to a drink intercept valve having an obturator and a valve seat, with the obturator being rotatable relative to the valve seat so that the drink can flow between the third passageway and into a drink delivery line. Actuation of a single command lever connected to the tubular element and the obturator causes the tubular element to slidably move between the end run positions, which in turn causes movement of the rack and pinion links and an opening and closing of the drink intercept valve.
