Abstract
The invention relates to a coffee brewing machine which is particularly suitable for family use and for a small commercial establishment, such as a refreshment room. The machine extracts the coffee beverage from a pod which contains ground coffee and is housed in a chamber defined by an upper block and by a removable lower box, between a jet-forming member fixed to the upper block and a filter housed in the removable lower box. It includes a water container, a heater and a pump which supplies the water to the chamber at the proper temperature and pressure. In the chamber the water penetrates the pod and extracts the coffee beverage therefrom and then the coffee beverage flows out of the machine.
