ABSTRACT:
A coffee machine, which operates with filter capsules, having a brewing unit with two brewing-chamber parts which can be displaced relative to one another and, in a closed position, form a brewing chamber for the filter capsules, one of the two brewing-chamber parts being connected to a brewing-water heater and being provided with a multiple nozzle. By virtue of the fact that the multiple nozzle in the brewing-chamber part is arranged in a movable manner and that, at least while the coffee is being prepared, is forced in the direction of the other brewing-chamber part or of the filter capsule accommodated in the brewing chamber, the extraction values are improved, the use of filter capsules of different thicknesses is possible, and the situation where the filter capsules swell up and explode when subjected to the action of superheated steam is avoided.
