ABSTRACT:
A coffee machine (1) with a brewing apparatus (7) is described which has a brewing chamber (9) and a piston (37) being movable to and fro herein. One of the front sides of the brewing chamber (9) contains an opening (44) which is cleared by a closing element (8) in one of its positions (I) for apportioning coffee powder and is closed in another position (II). A stripper (48) is provided for stripping off and ejecting the used up coffee grounds. In order to constructionally simplify such a coffee machine and to make it operatively more reliable and more robust, it is suggested to move the closing element (8) only relative to the brewing chamber in a plane extending in parallel to the opening (44) and to couple the stripper (48) to the closing element (8) in its movement.
