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
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.

Automatic coffeemaking machine comprising, in a housing (1), a fixed body (2) which comprises a cylinder (3) closed on one side by a cover (4) and on an opposite side by a ferrule (5) traversed by a rotatable shaft (6) connected to motorized means (7), and in which are provided openings, an opening
Automatic coffeemaking machine comprising, in a housing (1), a fixed body (2) which comprises a cylinder (3) closed on one side by a cover (4) and on an opposite side by a ferrule (5) traversed by a rotatable shaft (6) connected to motorized means (7), and in which are provided openings, an opening (8) for passage of grind being adapted for the introduction of a quantity of ground coffee (M), an opening (11) for feeding liquid being adapted to introduce a quantity of hot water from a water heater (12), a passage (13) for evacuation of infusion, and an opening (14) for ejection of grounds, said cylinder (3) being adapted to close a cylindrical infusion chamber (15) and comprising a piston (17) having a front face (16) and being slidably mounted in the cylinder (3) by translatory drive means (18) fixed in rotation with said shaft (6), said piston being adapted to occupy at least two positions comprising either a rest position in which the piston (17) is retracted from the opening (8) of the grind passage, permitting the flow of said grind (M) into the chamber (15), or a packing position in which the opening (8) for passage of the grind is closed, the piston (17) packing the grind (M) above the ejection opening (14) against the cover (4), and a tubular jacket (19) which is slidably mounted within the cylinder (3) by means of an actuating device (20) connected to the shaft (6), the piston (17) being itself mounted slidably in the jacket (19), and which comprises a filling opening (25) provided in a lateral wall of said jacket (19), said jacket (19) being adapted to occupy two positions comprising either a filling position in which the jacket (19) comes into abutment against the cover (4) and closes the opening (14) for ejection of grounds, causing the filling opening (25) and the opening (8) for passage of the grind to coincide, and in which the piston (17) passes from said rest position to said packing position, or an ejection position in which the jacket (19) closes the opening (8) for passage of the grind, leaving open the opening (14) for ejection of the grounds, and in which after ejection of the grounds, the piston (17) passes from said packing position to said rest position, said positions being differentiated from each other by a selector (35) of the number of revolutions of the rotatable shaft (6), wherein the translatory drive means (18) of the piston comprises a double thread screw (26) mounted rotatably in the body (2) and whose axis is parallel to the direction of movement of the piston (17), said screw (26) comprising at least two helicoidal paths (27, 28) comprising a pressure path (27) and a retraction path (28), said paths being wound in opposite directions from each other and interconnected by a rounded portion (29) at their respective ends so as to constitute together an endless path for a shoe (30) which is movably mounted in the piston (17), such that the continuous rotation of the screw (20) in the same direction effects a displacement of the piston (17) alternatively from one position to the other and wherein the actuating device (20) of the jacket (19) comprises a revolving cam (23) constituted by a helicoidal groove in which is disposed a finger (24) integral with the jacket (19) such that continuous rotation of the cam (23) in the same direction produces displacement of the jacket (19) alternately from one position to the other.
