  • Patent number: 4545296
    Abstract: An apparatus for making coffee includes a housing which bounds a catch chamber provided with a discharge through which any liquid present in the catch chamber is discharged into a receptacle, so that a rotary body which is mounted in the catch chamber for rotation about an axis rotates in air. The rotary body includes an internal space which is subdivided by a partition into two compartments which communicate with one another at their outer ends. Liquid is discharged from one of the compartments into the catch chamber through a port situated at the inner end of such compartment, while hot liquid is introduced into the inner end of the other compartment and flows therethrough and the quantity of ground coffee contained therein to extract flavor from the latter. The rate of discharge is determined solely by the rate of replenishment, since the two compartments behave as connected vessels or a water trap.
