Abstract
An extraction device for producing coffee for a coffee machine is equipped with a brewing cylinder () for receiving coffee powder. The brewing cylinder is reciprocably adjustable between pre-determined positions along its axial direction in co-operation with a drive mechanism (). Two pistons () that are coaxially adjustable relative to one another, are located in the brewing cylinder (). The brewing cylinder () incorporates a cylinder section (), and an additional part () is also envisaged. The additional part () is moveably located at an end of the brewing cylinder () that can be closed by the first piston () and equipped with a filler opening () for the insertion of the coffee powder. In this way the length of the extraction device can be shortened.
