Abstract: A device for on-site dispensing of a beverage containing a liquid and a gaseous substance dissolved therein is described. The device includes a dispenser, and a conduit for supplying the beverage to the dispenser. The conduit is configured to be connected to a container suitable for containing at least liquid for obtaining the beverage. The device further includes a pusher for imparting to the beverage a push sufficient to enable the dispensing of the beverage via the dispenser according to a predetermined dispensing condition. Furthermore, the device can include a pressure modulator for modulating the pressure in the conduit, a pressure reducer to be introduced into the container, and a compensator for improving the operation of the device on the basis of one or more automatic controls thereof.

Abstract: A device (90) for on-site dispensing of a beverage containing a liquid and a gaseous substance dissolved therein is described, the device comprising a dispensing means (60), and a conduit (40) for supplying the beverage to said dispensing means (60), wherein said conduit (40) is configured to be connected to a container (10) suitable for containing at least liquid for obtaining said beverage. The device further comprises a pushing means (20, 20?) for imparting to the beverage a push sufficient to enable the dispensing of the beverage via said dispensing means (60) according to a predetermined dispensing condition. Furthermore, the device can comprise a pressure modulating means (30) for modulating the pressure in the conduit, a means for reducing the pressure to be introduced into the container, and a compensation means for improving the operation of the device on the basis of one or more automatic controls thereof.

Abstract: A device according to the present invention is of the post-mix type for dispensing beverages on a user's premises and mixing at least a first component (10) and a second component (20) to obtain a beverage. The device comprises a flow measuring means (100) configured to produce measurement information relating to the flow of the first component; a flow rate adjustment means (250) configured to vary the flow rate of the second component; a control means (300) configured to receive the measurement information (32) and to control the flow rate adjustment means (250) on the basis of the measurement information and a predetermined parameter; and a mixing means (400) disposed downstream of the flow rate adjustment means and configured to mix the first (12) and second (22) components.

Abstract: The present invention relates to a pump for transferring liquids, in particular for beer or carbonated beverages, characterized in that it is constituted by two mutually opposite and integral pistons sliding inside two cylinders which generate, with their reciprocating motion, four variable-volume chambers inside two of which the fluid, through suitable valves, is alternatively intaken and delivered by a gas whose pressure is modulated by a suitable pressure regulator, in which it is the pressure of the same delivered liquid to counteract the calibration force, with said gas alternatively going to act, by means of suitable control means, inside the chamber behind the delivery chamber, so that the delivery pressure of the same liquid remains constant and predetermined, wherein said delivery pressure is obtained as the sum of the thrust of the liquid intaken from the opposite chamber, plus the modulated gas pressure, which acts on the rear face of the delivery piston.
