A device for hot beverages, such as coffee, tea, herbal tea, comprises a
lower container for receiving water, an upper container for receiving
brewed beverages, and a grounds holder assembly with an injector
differential system, into which coffee ground, tea leaves and herbs are
placed. The grounds are subjected to high temperature water and steam, to
extract essences and produce a beverage, such as espresso coffee, tea,
chamomile and others. The injector differential system has an injector
nozzle an injector floating piston in the lower portion of the hollow
stem. Pressurized hot water and steam from the lower container flow
through the injector nozzle, lifting injector floating piston, at
predermined high temperature and pressure, through the holes of lower
perforated plate, and then into the grounds for brewing process. The water
and stem extract of the grounds pass through inverted funnel and it is
collected into the upper cylindrical container.
