Hydraulic unit for dispensers of carbonated water

A hydraulic unit for a carbonation apparatus having a carbonator and a pump, wherein the hydraulic unit has a body made of polymeric material defining a plurality of ducts, which comprise a duct to convey water to the carbonator, a duct to add a gas to the carbonator, and at least one duct to draw water from the carbonator,

• wherein the plurality of ducts comprises a plurality of ducts selected from among:
• a first duct, having a first supply inlet, configured for connection to a water supply source, and a first dispensing outlet,
• a second duct, having a second supply inlet, configured for connection to a gas supply source,
• a third duct, for introduction of pressurized water into the carbonator, having a delivery inlet configured for connection to an outlet of the pump,
• a fourth duct, having a second dispensing outlet, for cooled water, susceptible of fluidic connection with an inlet of the pump,
• a fifth duct, having a third dispensing outlet, for carbonated water,
• wherein the body made of polymeric material also defines a fluidic connection interface, configured for mounting the body made of polymeric material at one connection end of the carbonator,
• wherein the fluidic connection interface defines one or more inlets and one or more outlets selected from among:
• a water outlet, which is configured for connection to a respective first inlet of the carbonator,
• a gas outlet, which is configured for connection to a respective second inlet of the carbonator,
• a pressurised water outlet, which is configured for connection to a respective third inlet of the carbonator,
• a cooled water inlet, which is configured for connection to a respective first outlet of the carbonator, and
• a carbonated water inlet, which is configured for connection to a respective second outlet of the carbonator,
• and wherein:
• the water outlet is in fluid communication with the first duct in an intermediate position between the first supply inlet and the first dispensing outlet,
• the gas outlet is in fluid communication with the second duct;
• the pressurised water outlet is in fluid communication with the third duct,
• the cooled water inlet is in fluid communication with the fourth duct, and
• the carbonated water inlet is in fluid communication the fifth duct.
