1. A brewing device for producing a beverage from two differently sized capsules, the brewing device comprising:
two parts opposite and mutually movable between an open or loading position in which a capsule is loadable between the two parts, and a closing or brewing position in which the two parts are coupled and define therebetween a brewing chamber housing the capsule; one of the two parts of the brewing device includes a cup-shaped body including a first portion and a second portion defining therebetween a seat designed to receive the capsule during the movement of the cup-shaped body towards said closing position; the second portion is designed to slide with respect to the first portion between a smaller seat position, in which the seat is sized to house a smaller capsule, and a larger seat position, in which the seat is sized to house a larger capsule; and
an actuator configured to move the cup-shaped body from the open position to the closing position, and vice versa;
wherein the first portion includes an outer cup, which includes a side wall and a bottom wall, and the second portion comprises an inner cup, which is arranged inside the outer cup and comprises a side wall slidably coupled to the side wall of the outer cup, and a bottom wall; the inner cup is normally arranged in an extracted position, in which the inner cup and the outer cup define therebetween said smaller seat position, and is mounted to slide inside the outer cup, as a result of the interaction of the inner cup with the larger capsule during the movement of the cup-shaped body towards the closing position, so as to move from the extracted position to a retracted position, in which the inner cup and the outer cup define therebetween said larger seat position;
wherein the actuator is configured to keep the outer cup still in the closing position and include a blocking device configured to define, in the closing position, an axial block for the inner cup only when, in the closing position, the inner cup is arranged in the extracted position or smaller seat position, so as to prevent the inner cup from backwardly moving towards the bottom wall of the outer cup under the thrust of a pressurized fluid injected in the smaller capsule; and
wherein the outer cup and the inner cup are so sized that, when, in the closing position, the inner cup is in its retracted position or larger seat position, the bottom wall of the inner cup abuts against the bottom wall of the outer cup so as to prevent the inner cup from backwardly moving under the thrust of the pressurized fluid injected in the larger capsule; and
wherein the blocking device is configured such that a dedicated actuation device is not required for the blocking device to become operative, and the blocking device is automatically activated when the seat houses the smaller capsule and is not active when the seat houses a larger capsule.
