Abstract: A delivery unit (1) for an apparatus for making a beverage, in particular for making an espresso coffee. The delivery unit (1) includes a cup-shaped body (2) delimiting an inner chamber (20), the cup-shaped body (2) including a lateral wall (21) and a bottom wall (23). The delivery unit (1) also includes an infeed spout (3) for introducing beverage into the inner chamber (20) and an outfeed opening (45) through which the beverage can come out of the inner chamber (20), the outfeed opening (45) being positioned in a central portion of the bottom wall (23). In the inner chamber (20) the delivery unit (1) includes a partition wall (5) which surrounds the outfeed opening (45) and divides the inner chamber (20) into a peripheral region (26) and a central region (28) in which the outfeed opening (45) is located. The partition wall (5) includes a plurality of passage openings (55) for allowing the beverage to pass from the peripheral region (26) to the central region (28).

Abstract: A heating and emulsifying device (10), particularly for heating and optionally emulsifying air and milk in milk-based products and having the capability to regulate the air-flow and the milk-flow jointly and proportionally, comprises an emulsification chamber (12) having an opening (14) for the delivery of the product and a steam-inlet duct (20) which opens into the emulsification chamber (12). A milk-inlet duct (28) and an air-inlet duct (30) communicate with the steam inlet duct (20), the air and the milk being drawn in by the partial vacuum created by the flow of steam. An air-flow regulator (38) and a milk-flow regulator (40) are operatively associated with the air-inlet duct (30) and with the milk-inlet duct (28), respectively, the air-flow and milk-flow regulators being structurally connected and being suitable for varying the respective flow-rates in proportion with one another and the emulsion/milk ratio in the final product, without affecting its temperature.

Abstract: A device for heating and emulsifying liquids, in particular drinks, which is unusually capable of generating a dense and creamy foam, comprises a steam-emitting member with which a hollow body can be associated. The steam-emitting member comprises a spout positioned along the hollow body at a height such as to be above the level of the liquid to be emulsified. Inserted coaxially inside the hollow body is a duct which defines a first passage and a second passage. A region for communication between the first passage, the second passage and a third passage for air, which is placed in communication with a groove formed in the inner surface of the hollow body, is provided between the steam-emitting member and the duct. The steam-emitting member comprises two annular projections provided with sectors which have different transverse dimensions and which are offset relative to one another and define a labyrinthine path.

Abstract: A manually operated coffee-making machine comprises, water storage reservoir and a hand-operated pump element which extends into the interior of the reservoir. The pump element is actuatable from the exterior of the reservoir. The delivery side of the pumping element is connected to an infusion chamber assembly which accommodates the coffee powder and is in communication with a dispensing tap opening to the exterior of the reservoir. An hydraulic accummulator is also provided. This hydraulic accummulator branches off a conduit connecting the delivery side of the pumping element to the infusion chamber assembly.

Abstract: A device for heating and emulsifying milk, especially to prepare a white coffee drink known as "cappuccino" with the assistance of a steam jet, which has a vacuum chamber surrounding a nozzle and formed with an emulsion discharge port, a passageway for admitting sucked-in air, and at least one passageway for the milk which enters the chamber on account of the negative pressure prevailing therein, thereby milk, air, and steam are mixed together in said chamber and then made to flow out through said discharge port.

Abstract: An emulsifier unit particularly for emulsifying steam and milk to prepare "cappuccino's" comprises a steam delivery conduit in communication with a steam generator and opening into a suction chamber into which a milk delivery conduit is led, said suction chamber being in communication with an emulsifying chamber provided with an outward dispensing opening.
