A coffee-making apparatus has a brew-water chamber for containing heated brew water, a coffee chamber, a water delivery system for delivering heated brew water from the brew-water chamber to the coffee chamber, and a cooling apparatus for cooling the heated brew water before it reaches the coffee chamber. The water delivery system comprises a conduit and a valve, openable when the pressure at a valve inlet reaches a valve opening pressure, for controlling a flow of brew water into the coffee chamber. The water delivery system is configured to control the flow rate of brew water while the coffee chamber is filling with brew water. A method of making coffee is also provided.

The invention describes a device for preparing infüsions, suitable for preparing infüsions in a micro wave. The device comprises: a lowertank transparent to electromagnetic radiation, with a valve; an upper tank screwed to the lower tank; a funnel that connects the tanks; an extraction área containing material to be extracted with filtering means; a cover; and means for making the device leak tight, the device comprising áreas for shielding against electromagnetic waves in the extraction área, the upper tank and the cover. In the preferred embodiments, the device comprises a float, needles and thermal reinforcement áreas. The device allows infüsions to be obtained without the volatile compounds degrading.

A moka pot includes a lower chamber, an upper chamber connected to the lower chamber, the upper chamber having a handle mount, and a handle. The handle has a first end pivotally attached to the handle mount and a second end spaced away from a side of the upper chamber. The handle is pivotable between a first position in which the handle extends along the side of the upper chamber and a second position in which the handle extends away from the upper chamber such that the second end of the handle is spaced further from the side of the upper chamber in the second position than in the first position.

A beverage brewing device includes a lower container for receiving and heating water, a connected upper container for receiving beverage, and a piston-cylinder assembly for receiving grounds, captured within the lower container. The piston-cylinder assembly includes a cylinder, a piston movable in the cylinder, a conical diffuser fixedly attached to the piston, and a freely movable mass disposed between the piston and the conical diffuser. The piston and the conical diffuser define an expansion chamber therebetween. The chamber is formed between a diffuser plate forming the top of the piston and an inner conical surface of the diffuser, which defines an orifice functioning as a nozzle. The diffuser plate has a plurality of holes, on which the grounds are placed. The mass is seated at a valve seat at the entrance of the expansion chamber to operatively block the flow of fluid through the nozzle when the pressure of the fluid is insufficient to displace the weight of the mass. When water is heated in the lower container becomes pressurized sufficiently to pass through the nozzle and displace the seated mass from the valve seat, the water passes through the nozzle at relatively high pressure and velocity, and enters the expansion chamber at lowered pressure. It then flows through the diffuser plate, through the grounds, and into the upper chamber.

An espresso coffee machine comprising at least one dispensing group (1003) which dispenses shots of espresso coffee, a pressure sensor (24, 25) positioned at the dispensing group (1003), a measuring device and a control unit (30) is described. The pressure sensor (24, 25) provides values of the dispensing pressure (P1) in the dispensing group (1003). The measuring device provides values indicating the amounts of liquid at the inlet or the outlet of the dispensing group (1003). Using the values of the dispensing pressure (P1) received from the pressure sensor (24, 25) and the values indicative of the amount of liquid which are received from the measuring device, the control unit (30) controls the dispensing pressure (P1) of each shot according to a profile of the dispensing pressure (P1) as a function of the amount of liquid.

A plate filter for coffee makers and the like, such as moka pots, Neapolitan flip coffee makers, coffee presses, or percolators, comprises a filtering wall (6a) provided with a plurality of holes or apertures (8) that define as a whole a substantially mesh-like structure having, according to the DIN 791 standard, a long side of mesh pitch or major diagonal (DL) that is less than 2 mm±5%, in particular comprised between 0.1 and 1.9 mm±5%, preferably comprised between 0.6 and 1 mm±5%, and even more preferably of 0.85 mm±5%.

A coffee maker which has a funnel ending with a funnel mouth and a foaming device applied to the funnel mouth is provided. The foaming device has a valve made of deformable material provided with an outlet mouth towards which an exiting percolated beverage is channeled. In a rest condition, in which the valve does not cooperate with the funnel, the at outlet mouth has a rest passage section. In a mounting condition, in which the valve cooperates with the funnel, the outlet mouth is deformed and has a working passage section, reduced as compared to the rest passage section.

A machine for the preparation and dispensing of espresso coffee is described, said machine comprising: a coffee boiler, a filter holder with a filter for a pressed coffee powder puck, a pre-infusion chamber and a hydraulic circuit for transporting pressurized water from said coffee boiler to the pre-infusion chamber, wherein said machine further comprises a device for detecting a parameter indicative of the filling of said pre-infusion chamber and of said hydraulic circuit so that the step of dispensing of an espresso coffee can be started on the basis of said defected filling parameter.

The invention describes a device for preparing infsions, suitable for preparing infsions in a micro wave. The device comprises: a lowertank transparent to electromagnetic radiation, with a valve; an upper tank screwed to the lower tank; a funnel that connects the tanks; an extraction rea containing material to be extracted with filtering means; a cover; and means for making the device leak tight, the device comprising reas for shielding against electromagnetic waves in the extraction rea, the upper tank and the cover. In the preferred embodiments, the device comprises a float, needles and thermal reinforcement reas. The device allows infsions to be obtained without the volatile compounds degrading.

A novel self-tending coffee maker is disclosed. The device includes a top pot, a bottom pot, a funnel disposed between the top pot and bottom pot, a base disposed about the bottom pot, and a means for lifting the bottom pot away from the base. The lifting means may be pneumatically actuated such as by way of a pneumatically actuated piston arrangement, heat actuated, or the like. In a variant of the pneumatically actuated piston arrangement, the lifting means may further include a retaining screw in communication with the piston rod for creating a pre-load setting against the spring, wherein the retaining screw is coupled to the base. With this set-up, the funnel preferably includes at least two legs in communication with the top pot.
