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.

[ What is claimed is:] [1.] An apparatus for using a coffee-filled filter capsule to produce a coffee beverage comprising:a brewing unit having a pair of brewing chamber sections being movable relative to one another, between an open position for receiving the filter capsule and a closed position to form a brewing chamber for brewing the coffee; andat least one of the brewing chamber sections having a nozzle assembly in fluid communication with a water heater for admitting heated water into the brewing chamber, the nozzle assembly comprising a nozzle plate having at least one water nozzle wherein the nozzle plate compresses the filter when the brewing unit is in the closed position and heated water passes through at least one nozzle, also including a spring adjacent the nozzle assembly for acting with hydraulic pressure to urge the nozzle assembly toward the filter.
