Abstract

A system for the preparation of beverages with the use of capsules including an infusion assembly (1) and a capsule (C). The infusion assembly includes a capsule-holder (2) and a cooperating body (3), adapted to assume an open configuration for positioning a capsule (C) therebetween, and a closed configuration for preparing a beverage through the capsule (C) clamped in a liquid-tight manner therebetween. In the capsule-holder (2) there is defined a recess (4) adapted to receive the capsule (C) with the bottom wall (20a, 20f) facing the interior of the capsule-holder (2) and wherein is provided a first piercing member (8) provided with at least a piercing point (9) adapted to penetrate through the bottom wall (20a) of said capsule (C). The capsule-holder (2) is adapted to supply a flow of fluid introduced into the capsule (C) through the tear created in its bottom wall (20a) from the at least one point (9). In the cooperating body (3) a dispensing conduit (13) is defined for the beverage and a second piercing member (14) is provided, having at least one point (16) adapted to penetrate through the cover (21) of the capsule (C) to allow the outflow of the beverage from the capsule (C) towards said dispensing conduit (13). In the capsule-holder (2) there are provided fluid communication passages (8c; 8d; 11), which put into communication a region upstream of the first piercing member (8) such that, during the preparation of a beverage, the fluid introduced into the recess (4) of the capsule-holder (2) exerts on the first piercing member (8) a force lower than a predetermined value towards the capsule (C), the first piercing member (8) being mounted in the recess (4) of the capsule-holder (2) such as to be movable under the action of a spring (10) tending to displace it towards the cooperating body (3).
