Abstract
A machine (100) for preparing coffee includes a boiler (40) for water in which a funnel-shaped filter (7) configured to contain the coffee is positioned, a collector (15) to collect the drink end that comes out from a collection duct (45), electrical power supply means (3), an element (18) for electric heating of the liquid in the boiler (40), a valve (44) interposed between funnel filter (7) and boiler (40), which can be closed again to allow a pre-set temperature and pressure to be reached inside the boiler (40), before being reopened to bring water and steam from the boiler (40) to the coffee contained in the funnel filter (7), air pumping means (20), an electronic system for controlling water and steam delivery from the boiler (40).

1-10. (canceled)
A machine for making coffee, the machine comprising:
- a boiler for the water in which a funnel filter configured to contain the coffee can be positioned;
- a collector connected to the boiler and engageable with said boiler, configured to collect the final drink that comes out of a collection duct;
- electrical power supply means;
- an element for electric heating of the liquid in the boiler;
- air pumping means to vary the pressure inside the boiler by introducing or extracting air;
- an electronic control system for the delivery of water and steam from the boiler to the collector through the funnel filter, configured to control and command the air pumping means;
- a valve interposed between the funnel filter and the boiler, which can be closed again so as to prevent communication between the boiler and the funnel filter to allow reaching inside the boiler a pre-established temperature and pressure, before being reopened to connect the boiler and the funnel filter and bring the water and steam from the boiler to the coffee contained in the funnel filter;
- and
- an electronic control system of water and steam delivery from the boiler to the collector through the funnel filter, configured to control and command the valve.
