<p>A coffee maker (10) comprises a boiler (11) designed to contain the water which is to be heated up, a coffee vessel (15) designed to hold a given amount of coffee powder, and a collecting vessel (12) designed to collect the coffee infusion produced as the hot water passes through the coffee powder; the coffee vessel (15) is in communication on the one hand with the inside of the boiler (11) and on the other hand with a duct (21) through which the coffee is dispensed; so that the coffee produced may be similar to that prepared using espresso coffee machines, valve means (22, 23) are provided along the path travelled by the hot fluid from the boiler (11) to the collecting vessel (12), which close off the said path in order to create a predetermined overpressure in the boiler (11) with respect to atmospheric pressure and which open up once the said overpressure in the boiler (11) has been attained.</p> |
