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). |
