A device for moistening a set of nozzles for dispensing fluids in a dispensing machine has a support for the nozzles and a hollow member movable selectively along a predetermined path from a first position in which the set of nozzles is covered to a second position in which the nozzles are uncovered; in the position in which the set of nozzles is covered, the hollow member cooperates with a sealing element to define a first closed chamber; an isolation element movable selectively relative to the hollow member cooperates with the nozzle support to define at least one second closed chamber which is disposed inside the first closed chamber and in which at least one nozzle of the dispensing machine emerges.
