Abstract: An infusion unit includes an infusion chamber for coffee or other product where, through water under pressure, flavors are extracted for making a beverage. The infusion chamber includes at least one yielding wall for adjusting a volume of the closed infusion chamber according to the amount of product contained into the infusion chamber. Moreover, a variable volume chamber is provided, which is filled with a liquid and connected to the yielding wall, so that a volume of the variable volume chamber filled with liquid varies according to a position taken by the yielding wall when the infusion chamber is closed. The position of the yielding wall is locked when the infusion chamber is closed, preventing the liquid flow from and into the variable volume chamber filled with liquid.

Abstract: A jug for the preparation of beverages is provided. The jug (1) comprises a body (5) with at least a first receptacle (23) and a second receptacle (25) for receiving ingredients for the preparation of beverages. A first stirrer (17) can be arranged in the first receptacle (23). In some embodiments, a second stirrer (19) can be arranged in the second receptacle (25). The jug also comprises a cover closing the body of the jug. A first fluid connection (51) is arranged for receiving a beverage from a beverage producing machine and collecting the beverage in the first receptacle (23). A second fluid connection (77) to a beverage producing machine is further provided, in fluid communication with the second receptacle (25).

Abstract: A holder includes a grid and a tray below to collect any liquids flowing through the grid. The grid and the tray are mutually constrained magnetically.

Abstract: A hydraulic circuit for instant beverage machines includes a tank, a water extraction pipe contained in the tank, a flow-meter connected to the extraction pipe, a pump, a first vibration-damping valve, a boiler, a second relief and safety valve, a water/steam faucet, a third beverage flow valve, and a recovery tank.

Abstract: The brewing assembly comprises: a brewing chamber (21, 31, 41); a support structure (17, 19) carrying a first portion (21) and a second portion (23) of the brewing chamber; and a boiler (51) for heating water. The support structure has a first part (17) which is fastened to the first portion (21) of the brewing chamber, and a second part (19) which is fastened to the second portion (23) of the brewing chamber. The first and second parts of the support structure can be mutually coupled and uncoupled. The first and second portions of the brewing chamber are mutually mobile to adopt an open position, and a closed position when the first and second parts of the support structure are coupled. The boiler (51) is rigidly connected to one of the parts of the support structure and to one of the portions of the brewing chamber.

Abstract: The infusion unit comprises an infusion chamber (25, 31) for coffee or other product wherefrom, through water under pressure, the flavours are extracted for making the beverage. The infusion chamber comprises at least one yielding wall (33) for adjusting the volume of the closed infusion chamber to the amount of product contained into said infusion chamber. Moreover, a variable volume chamber is (49) provided, filled with a liquid and connected to the yielding wall (33), so that the volume of the variable volume chamber filled with liquid varies according to the position taken by said yielding wall (33) when the infusion chamber is closed. The position of the yielding wall (33) is locked when the infusion chamber is closed, preventing the liquid flow from and into said variable volume chamber filled with liquid.

Abstract: The coffee machine (1) comprises: at least a coffee supply module (7); a support surface (9) for cups, arranged beneath said coffee supply module (7); at least a first steam supply nozzle (13), to which a milk container (15) can be connected, equipped with an emulsifying module (12) having a connection seat in which the first steam supply nozzle is inserted when the container is connected to the steam supply nozzle. The emulsifying module comprises a pipe for sucking up milk from the container and a nozzle for supplying hot or emulsified milk (67). The steam supply nozzle (13) is oriented toward the support surface (9) and the connection seat of the container (15) is oriented upwardly when the container is placed on the support surface (9) with the first steam supply nozzle (13) inserted in the connection seat.

Abstract: The container (9) comprising an emulsifying device (17) having a milk suction pipe (37), a nozzle (19) for supplying hot or emulsified milk with a discharge end outside the container, a steam inlet (33) and an air inlet (40).

Abstract: The invention provides a device for connecting a refrigerated compartment wherein milk, or other perishable liquid is contained, to a device for supplying hot or emulsified milk, which can be associated to a coffee machine or the like. The connection device has at least a portion which can be refrigerated by the effect of the coupling of the compartment wherein the milk container is contained.

Abstract: The coffee machine comprises: a water tank (11); at least one first pump (17); at least one first boiler (31) for heating the water; a coffee brewing unit (25); and circuits to feed hot water and/or steam, with a first outlet (43) for hot water or steam towards an emulsifying device which can be connected to a connection joint (35) of the coffee machine; a second outlet for hot water and/or wash water.

Abstract: The holder (3) comprises a grid (7) and a tray below (5) to collect any liquids flowing through said grid. The grid and the tray are mutually constrained magnetically.

Abstract: Hydraulic circuit for instant beverage machines comprising a tank, a water extraction pipe contained in said tank, a flow-meter connected to said extraction pipe, a pump, a first vibration-damping valve, a boiler, a second relief and safety valve, a water/steam faucet, a third beverage flow valve, a recovery tank.

Abstract: A steam unit, in particular for a machine for espresso beverages, includes a supporting island with external fastening, which connects removably to the machine; a tank for frothing milk, the base of which connects removably to the supporting island, which in turn comprises an electro/hydraulic circuit to deliver steam from the machine to the tank, by means of the connection at the base of the tank, said tank including an upper part for heating and emulsifying the beverages.
