A beverages dispenser, particularly for carbonated beverages, comprises a cooled tank where beverage is stored, an inlet pipe to the tank, an inlet valve on the inlet pipe, a pump downstream the inlet valve for feeding a beverage to the tank in order to maintain a predetermined level wherein, an outlet pipe from the tank to a beverage dispensing nozzle, and an outlet valve on the outlet conduit. An auxiliary pipe is disposed between the inlet pipe downstream the inlet valve and the outlet pipe downstream the outlet valve and a control unit is adapted to close the inlet valve and to run the pump in order to empty the outlet pipe into the tank after the beverage is dispensed in order to prevent dripping.

1. Beverage dispenser, for carbonated beverages, comprising at least a cooled tank where beverage is stored, an inlet conduit to the tank, an inlet valve on the inlet conduit, a pump downstream the inlet valve for feeding a beverage to the tank, an outlet conduit from the tank to a beverage dispensing nozzle, and an outlet valve on the outlet conduit, said beverage dispenser comprising: an auxiliary conduit disposed between the inlet conduit downstream the inlet valve and the outlet conduit downstream the outlet valve; anda control unit adapted to close the inlet valve and to run the pump in order to empty the outlet conduit into the tank after the beverage is dispensed. 2. Beverage dispenser according to claim 1, wherein the auxiliary conduit comprises a check valve preventing the flow of beverage from the inlet conduit to the outlet conduit. 3. Beverage dispenser according to claim 1, wherein the tank is adapted to contain carbonated water and is provided with a conduit contained therein for feeding cooled water to the dispensing nozzle by means of a second outlet valve on an auxiliary outlet conduit connected to said outlet conduit. 4. Beverage dispenser according to claim 3, wherein between the inlet conduit and the outlet conduit a by-pass conduit is installed for delivering still water from a tap water conduit to the dispensing nozzle. 5. Beverage dispenser according to claim 1, wherein the beverage dispensing system comprises a second outlet conduit connected to an auxiliary tank for hot water. 6. An apparatus for dispensing beverages comprising: a tank, wherein the tank is thermally connected to a cooling source;an inlet valve;an inlet conduit, wherein the inlet conduit is in adapted to provide fluid to the tank and the flow of fluid within the inlet conduit is affected by the inlet valve;a pump operatively connected to the fluid flow of the apparatus and downstream of the inlet valve;an outlet valve;an outlet conduit, wherein the outlet conduit is in fluidic contact with the tank and the flow of fluid within the outlet conduit is affected by the outlet valve;an auxiliary conduit located between the inlet conduit and the outlet conduit; anda control unit, wherein the control unit effectively drives the closing of the inlet valve and wherein the control unit effectively drives the operation of the pump, wherein the operation of the pump drives the emptying of the outlet conduit into the tank at the end of the beverage dispensing. 7. The apparatus of claim 6 wherein the cooling source is cold air. 8. The apparatus of claim 6 wherein the control unit includes a button that a user may activate. 9. The apparatus of claim 6 wherein the control unit is further adapted to detect a low level of fluid in the tank, and in response to a low level detection, the control unit ensures that the pump is operating and opens the inlet valve. 10. The apparatus of claim 6 wherein the control unit is further adapted to detect a targeted level of fluid in the tank, and in response to the targeted level detection, the control unit closes the inlet valve. 11. The apparatus of claim 6 wherein the auxiliary conduit comprises a check valve preventing the flow of beverage from the inlet conduit to the outlet conduit. 12. The apparatus of claim 6 wherein the auxiliary conduit flows fluid into the tank to prevent the flow of beverage from the outlet conduit following dispensing of the fluid.
