Title: (EN) APPARATUS AND PROCESS FOR EXTRACTING ESPRESSO COFFEE
(FR) APPAREIL ET PROCEDE D'EXTRACTION DE CAFE EXPRESSO
Abstract: front page image
(EN) 2082423 9116845 PCTABS00008 An improved process and apparatus for the extraction of espresso coffee from ground coffee beans in which the pressure of extraction is precisely regulated by a pressure valve (16) and is not dependent on coffee grind size, degree of compaction of the coffee grind, or operator skill. A feature of the invention is in an assembly of the brewing chamber (44) and regulator valve (48) for convenient removal and attachment to an expresso machine (10) as a unit (40) without otherwise modifying the machine. The assembly (40) is configurable with the regulator valve (48) within a common housing (41) which also defines the brewing chamber (44), or with a regulator valve (35) separate from the brewing chamber assembly (28) but attached to an outlet (33) of the brewing chamber (28).
