Abstract: The infusion unit (3) comprises a moving element (9) with a seat (15) for ingredients for making said beverages, forming an infusion chamber (15) and shifting from a position for charging the ingredients to an infusion position, wherein the seat is between a hot water dispensing device (41) and a beverage outlet nozzle (35) opposite one another. The hot water dispensing device (41) comprises a cylinder-piston actuator (43, 47) fed by a first conduit (48) of water under pressure that controls a closing movement of the dispensing device (41) towards the seat (15) in infusion position. Moreover, the piston (47) of the actuator is associated to a conduit (57) of hot water under pressure. The piston exhibits a feeding chamber (55) of the hot water under pressure with an outlet port on a closing surface (53A) of the infusion chamber.

Abstract: The beverage producing system comprises a beverage producing machine (1) and a jug (3). The beverage producing machine (1) is provided with a steam nozzle (41) and the jug (3) is provided with a steam duct (25) having a steam inlet end (25A) designed and arranged for connection to the steam nozzle (41). The steam nozzle (41) is housed in a recess (11) having an entry aperture (35), a bottom wall (39) and an upper ceiling (38). The steam nozzle (41) is arranged at the bottom wall (39) of the recess (11) and is oriented towards the upper ceiling (45). The steam inlet end (25A) of the steam duct (25) projects from the jug (3), such that a connection between the steam nozzle (41) and the steam duct (25) is established by introducing the steam inlet end (25A) in the recess (11) and by lowering the jug (3) until a fluid connection is established between the steam nozzle (41) and the steam inlet end (25A) of the steam duct (25).
