OG exemplary drawing
 
1. 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, and
a fifth duct, having a third dispensing outlet, for carbonated water,
and wherein the first supply inlet and the second supply inlet are at, or oriented towards, a first longitudinal end region of the body of polymeric material, and the first dispensing outlet, the second dispensing outlet and the third dispensing outlet are at a second longitudinal end region of the body of polymeric material which is opposite to the first longitudinal end region.
