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.
