<p>The assembly (1) comprises first and second portions (17, 18), at least one (17) of which is movable with respect to the other one (18) between an open position in which a capsule (C) can be introduced therebetween, and a closed position in which this capsule (C) is enclosed in an infusion chamber (19) for the preparation of a beverage. Between these portions (17, 18), the assembly (1) comprises means for positioning the capsule (C), including two opposite, rotatable, gates (23), with which respective resilient opposing means (24) are associated, which tend to keep them in a working position in which they are capable of forming guides or seats (26) for receiving and retaining in an intermediate waiting position a capsule (C). The capsule (C) is able to open the gates (23) and pass beyond them when the two portions (17, 18) of the assembly (1) pass from the open position to the closed position, these gates being capable of preventing a return of the capsule (C) to the intermediate position when the two portions (17, 18) of the assembly (1) return to the open position. The resilient means associated with each of the gates (23) comprise a flexion spring including an essentially L- or V-shaped resilient strip (24), with an outer anchoring portion (24a) fixed to one of the two portions (17, 18) of the assembly (1) in an orientation which is at least approximately parallel to the direction of movement (A-A), and an inner opposing portion (24d) which extends towards the direction of movement (A-A) and bears against the associated gate (23) on the side opposite the corresponding guide or seat (26) for the capsule (C).</p> |
