Abstract: A coffee maker which operates with at least one metering device having an adjustable wall, which varies the metering volume of the metering chamber. The metered powdered beverage is emptied through a movable flap and falls through a pouring funnel into an extraction chamber of an extraction cup. During the brewing process, a displaceable extraction piston is located in the brewing chamber. The movable wall and the movable extraction piston are actuated via a single operating element which acts on a transmission means.

Abstract: A device for preparing hot beverages such as coffee by extraction having an extraction cup (5) movable from an outset position to an extraction position along a control track (2) in a mounting plate (1) by a movable holder (4). The extraction cup (5) is detachably secured to the movable holder (4). The extraction cup (5) is filled from a coffee grinding unit (3) and is then displaced along the horizontal portion (2') of the control track (2) laterally until it is located vertically below an extraction piston (11), whereupon it moves vertically upward. In this manner, the ground coffee is compressed. Simultaneously, through a hot water inlet neck (8), communication with a hot water heater (10) is established. After the extraction, a stop (15) is displaced beneath a tappet (7) supported in the extraction cup (5) and keeps the tappet at the top of the extraction cup (5) during the downward motion of the extraction cup (5).
