ABSTRACT:
The invention relates to a device for the preparation of a coffee-based drink by extracting a dose of ground coffee contained in a capsule (8). Said device comprises a water reservoir (1), a pump (2), a heating body (15) and a water injection element (9) which are successively linked by means of a water supply line(3). The device also comprises the following items disposed in the extension of the water injection element (9): a capsule holder (7) and an outlet (10) for the water-coffee mixture. The capsule holder (7) is adapted in such a way that it can be fixed and manually removed from the device and comprises means for containing a coffee capsule (8) so that pressurized water from the water injection element (9) can flow through the capsule (8) and flow through the outlet (10). The inventive device is characterized in that it also comprises a derivation line (5) whereby one end thereof is connected to the water supply line (3) and comprises hydraulic means on the other end thereof, which are adapted in such a way that they can control the a coffee-water mixture discharged through the outlet (10). The inventive device also comprises a valve (4) which is disposed in such a way as to enable the discharge of water in the derivation line (5) when a predetermined pressure is obtained. The inventive device makes it possible for the user to define the pressure of the coffee-water mixture
