<p>The invention relates to an automated coffee brewing device comprising a screw (4) which cannot be moved axially and a nut (5) mounted thereto. A carriage (7) is connected to the aforementioned nut, said carriage defining a chamber (9) that houses a piston which can be moved along the length of the chamber. A rod extends (11) out from the lower end of the piston, the lower end of said rod comprising an enlarged area (13) having a groove (14) which can be blocked in an elastic manner by the lower opening (22). A support (16) is mounted to the upper cylindrical section of the above-mentioned screw (4) and can be moved in an angular manner around said screw. The support (16) bears a fixed piston (20) and a coffee loading funnel which are separated from each other in an angular manner and one of which can be disposed opposite the chamber (9) when the support (16) is moved angularly, driven by the part (17).</p> |
