A super automatic machine (1) for brewing coffee is characterized in that it comprises a rotor (2) which rotates about its own axis (A1) on a support (9) and drives along a peripheral cylinder (3) with a piston (4) sliding therein, the latter being connected via a rod (5) to a pin (6) that is fixed eccentrically to said axis of rotation (A1), thereby defining a bottom dead center and a top dead center; an aperture (2a) is defined on the rotor (2), level with the cylinder (3), for the dose of ground coffee to be loaded therein in a first angular position of the rotor (2) and for the infusion to flow out in a second angular position of the rotor (2); in a third angular position, downstream from said second position, the piston (4) ejects the used coffee grounds out of the same aperture (2a). Said first, second and third positions are covered in one full turn of the rotor (2). |
