摘要： A machine for the preparation of liquid products via capsules comprising a delivery assembly with a preparation chamber, which comprises a first part and a second part. The second part of chamber comprises an injector device, which is configured for introducing a preparation fluid into a capsule and has a hollow body and includes a first body part and a second body part. Defined between the two body parts is a chamber, housed in which is a perforation device having at least one front perforation element that is axially aligned to a respective through hole, defined in a front wall of the second body part of the injector device. The second body part is slidable, against the action of elastic means, from an advanced position, in which the at least one perforation element does not project substantially beyond the front wall, to a retracted position, where the at least one perforation element projects substantially beyond the front wall. The elastic means comprise a bending spring that extends in a direction transverse to the direction of axial sliding (X) of the second body part with respect to the first body part.

摘要： A motorized brewing unit for preparing beverages from a powdered product has a dispensing assembly having a first assembly part provided with a receptacle adapted to receive the powdered product, and a second assembly part, relative to which the first assembly part is movable between an open position and a closed position in which the first assembly part and the second assembly part are coupled to each other to define a brewing chamber therebetween. The motorized brewing unit has an electric motor that controls movement of the first assembly part between the open position and the closed position and a readout device that provides a digital image of the powdered product. The readout device has an optical sensor. The receptacle faces the optical sensor when the first assembly part is in a detection position, intermediate between the open position and the closed position.

摘要： A brewing unit, machine and system for the preparation of a beverage using prepackaged capsules. The brewing unit (1) includes a piercing and liquid-supplying device (23, 34, 35) having points (35) for piercing the top wall (12) of a capsule (C) and a conduit (36) for supplying a flow of pressurized liquid to a brewing chamber above the top wall (12) of the capsule (C) and thereafter inside the capsule (C) through the pierces holes in the top wall. A drawer (3) holds a capsule (C) such that its top wall (12) lies in an inclined plane. A discharge channel (40) is provided in the drawer and in fluid communication with the region above the top wall (12) of the capsule (C) when, after the beverage has been prepared and dispensed, the piercing and liquid-supplying device moves from the extracted work position to the retracted rest position to allow the remaining liquid to be poured into the discharge channel (40).

摘要： A brewing unit includes a first part having a receptacle for receiving a capsule, a cartridge or a compacted pod, a second part movable relative to the first part between an open position in which the first and second parts are at a distance from each other, and a closed position in which the second and first parts are coupled to one another to define a brewing chamber. An electric motor controls movement of the second part relative to the first part. A transmission mechanism arranged between the electric motor and the first or second part comprises a movable member whose position is univocally associated with the relative position of the second part with respect to the first part. An electronic control unit controls the electric motor. A micro-switch switches between an ON operational state and an OFF operational state depending on the position of the movable member.

摘要： A machine (1) for the preparation of liquid products via capsules comprises a delivery assembly (2) having an actuation system that can be controlled to cause relative displacements between a first part and a second part of a preparation chamber. The actuation system comprises at least one first transmission member (13) and one second transmission member (14a). The first transmission member (13) includes two pins (13a), which are coaxial and are engaged in corresponding seats (3d), defined on re-spective side walls of the housing structure (3). The seats (3d) define a fixed axis of rotation of the first transmission element (13). The second transmission member (14a) is connected in an articulated way to the first transmission member (13) for turning about a movable axis of rotation, parallel to the fixed axis of rotation, and to one of the first part of chamber and the second part of chamber. The pins (13a) have, in cross section, a non-circular geometry, and the side walls of the housing structure (3) have, in homologous positions, transverse passages (3f) that extend from the seats (3d). The first transmission member (13) is constrained to the second transmission member (14a) so as to move in an angular range that does not include an angular position of the first transmission member (13) such that the corresponding pins (13a) would slide out transversely of the rotation seats (3d) through the aforesaid transverse passages (3f).

摘要： A machine for preparing liquid food products includes a pump. A cylinder is defined in the pump casing, with a piston extending in the cylinder at least in part to define a variable-volume work chamber. Between a shaft of a motor and the piston there is a transmission arrangement for causing a reciprocating movement of the piston with a predetermined stroke between advanced and retracted positions, to vary a volume of the work chamber. The pump has an intake valve and a delivery valve, for connecting the work chamber with an inlet and an outlet of the pump casing, respectively. The transmission arrangement has an actuation member driven in rotation by the shaft and operatively coupled to the piston. The actuation member defines a cam path to which the piston is coupled. The cam path is prearranged for determining the predetermined stroke of the piston between the advanced position and the retracted position.
