Abstract
A coffee machine with a brewing apparatus is described which contains a brewing vessel disposed removably and insertably on a support by detachable fasteners. A piston driven by a motor via a piston rod and a gear pin is movable within the interior of the brewing vessel. In order to facilitate the removal and insertion of the brewing vessel in a given direction for cleaning purposes and to be able to also exchange the brewing vessel, if required, the piston is connected to the gear pin via a separable coupling, which can be separated or coupled by removal or insertion movement of the brewing vessel in the given direction so that the brewing vessel can be removed and inserted together with the piston as a unit.
