Abstract of the Disclosure In a coffee percolator having a brewing section, different operating positions are controlled by a control piston driven by a motor by the action of suitable control means. The control piston moves through a coffee meal supply open- ing and a coffee-grounds flushing opening, both of which are provided in said brewing section, for selectively or contemporaneously openign and closing these openings in the different operating positions. In a brewing position the control piston closes both openings, so that an overpress- ure is generated within the brewing section. Subsequent to the brewing operation this overpressure is relieved in a relief position by opening the flushing opening while said supply opening remains closed. The relief position is succeeded by a flushing position, in which the supply opening is likewise opened, so that the exhausted coffee- grounds can be flusehd out. In one embodiment, the brewing position is followed by the introduction of a short-time flushing water jet for loosening and agitating the coffee- grounds.
