<p>Guided on a circular path (R) is a brewing block (32) with brewing chambers (25, 26) which assume three different working positions and the brewing pistons (29, 30) and the sieve/expulsion pistons (36, 37) being moved axially in the brewing chambers (25, 26). The brewing unit (1) is driven and controlled via spur gears and cam discs, which are accommodated in two mutually opposite cam disc casings (59). According to the claimed method, the rotation to the three positions occurs in 30° steps, resetting being carried out through 60°.</p> |
