Abstract:
1. A device for producing a beverage from a capsule, comprising: an extraction module comprising a first jaw member and a cooperating second jaw member, in an opened state of the extraction module the first jaw member and the cooperating second jaw member are separated from each other while in the closed state the first jaw member and the cooperating second jaw member are in contact; a motor for controlling a movement of the extraction module between the closed and opened state; and a mechanical conversion means for transmitting a drive action of the motor into a relative displacement of the first jaw member and the cooperating second jaw member, the mechanical conversion means having a variable transmission ratio which varies during the movement of the extraction module between the opened and the closed state, wherein the mechanical conversion means is designed to convert the drive action of the motor into a closure force that increases during the movement to the closed state, wherein the mechanical conversion means comprises a lever arrangement connected to a spindle driven by the motor, wherein a rotational drive of the motor is converted into a translational drive through the spindle interacting with a thread of a drive shaft, and wherein the lever arrangement comprises two co-parallel pairs of levers, the levers of each pair of levers being respectively connected to each other by a knee joint, the motor actuating directly or indirectly on the knee joint.
