ABSTRACT:
A cylinder (3) is closed, on the one hand, by a cover (4) and, on the other hand, by a ferrule (5) traversed by a rotatable shaft (6). The cylinder (3) is so disposed as to close an infusion chamber (15) delimited by the cover and by a sliding piston (17) driven by a translatory drive (18) integral with the shaft. A jacket (19) is slidably mounted by an actuating device (20) connected to the shaft (6), the piston (17) is itself slidably mounted in the jacket (19), the different positions of the jacket and of the piston being defined relative to each other by a selector (35) of the number of rotations of the shaft. Application particularly for household coffeemaking machines.
