摘要 |
An improved machine for preparing a coffee infusion, in particular for home use has an unique construction including a plurality of elements, i.e. a water boiling chamber, on the top of which can be threaded a coffee infusion collecting chamber, having a filter containing the coffee powder. The machine is characterized in that, starting from the inside of the water boiling chamber and coaxially proceeding along a fitting cylindric element, there extends a hollow vertical cylinder in which a piston can be displaced, the piston causing in turn a given water amount to be displaced toward the filter.
