Abstract

A coffee machine has a low overall height and allows an attractive aesthetic design to be achieved in its execution. A brewing block comprising brewing chambers is guided over a circular path, the chambers adopting three different operating positions. Brewing plungers and straining/expelling plungers move axially in the brewing chambers. Drive and control of the brewing assembly is effected by way of spur gears and cam discs which are housed in two cam disc housings located opposite one another. In accordance with a method according to the invention, the rotation to the three positions takes place in steps of 30 degrees, with resetting taking place through 60 degrees.
