The present invention proposes a device (50) for preparing a beverage from a food substance contained in a capsule (24) by injection of a liquid into the capsule (24) provided to the device (50). Said liquid is provided by a pump of the device, said device comprising an extraction head (20) having an aperture (22) for inserting a capsule (24) into a brewing chamber (25) of the device. The brewing chamber (25) is defined by an upper and a lower enclosing member (10a,10b), a closing mechanism (1) to selectively enclose said capsule by a relative displacement of said enclosing members. The enclosing members are designed for being transferred between an open insertion position for inserting a capsule (24) into the brewing chamber (25) and a closed injection position for enclosing the capsule within the brewing chamber (25), and adjustment means (3a,3b,9b,9c,7a,7b,8a) connected to at least one of said enclosing members (10a,10b) in order to adjust the relative position of the enclosing members and hence the closing force of the closing mechanism (1). |
