Abstract
An infusion assembly, wherein a piston is positioned facing an open end of a cup, and is movable along a first axis to insert a container of powdered material into the cup; the container having been arrested, in use, by a gripper-type stop device in a position coaxial with the first axis and inside a through channel interposed between the piston and the cup; the gripper-type stop device being movable with and by the piston to perform a work movement towards the cup; and the cup having a second axis, and being mounted to oscillate, about a third axis perpendicular to the first axis, between a normal unloading position, in which the open end of the cup faces downwards, and a work position, in which the second axis is coaxial with the first axis.
Claims12
An infusion assembly comprising a cup (35) for receiving a container (2) of powdered material;
- a piston (16) facing an open end (40) of the cup (35) and movable along a first axis (8) to perform a work stroke, to and from the cup (35), between a withdrawn rest position, in which the piston (16) defines, with the cup (35), a channel (42) crosswise to the first axis (8) and for passage of the container (2), and an extracted work position, in which the piston (16) cooperates with the cup (35) to define an infusion chamber (41) for receiving the container (2) and through which pressurized fluid is fed;
- and stop means (43) located in front of the piston (16) to intercept the container (2) along the channel (42), and arrest the container (2) in a position coaxial with the first axis (8);
- the infusion assembly (1) being characterized in that the stop means (43) are movable with the piston (16) to perform a work movement towards the cup (35);
- and the cup (35) has a second axis (33a), and is mounted to oscillate, about a third axis (30) perpendicular to the first axis (8), between a normal unloading position, in which the open end (40) of the cup (35) faces downwards, and a work position, in which the second axis (33a) is coaxial with the first axis (8).
An infusion assembly as claimed in one of the foregoing Claims, and comprising guide means (44) extending parallel to the first axis (8) and for guiding the stop means (43) in their work movement;
- elastic means (55) being provided to impart to the stop means (43) a return movement opposite the work movement.
An infusion assembly as claimed in one of the foregoing Claims, wherein the work stroke of the piston (16) is longer than the work movement of the stop means (43).
An infusion assembly as claimed in one of the foregoing Claims, wherein the piston (16) is a telescopic piston comprising a first stage (17), which engages the stop means (43) to impart said work movement to the stop means;
- and a second stage (19) having piercing means (24) for piercing said container (2).
An infusion assembly as claimed in one of the foregoing Claims, wherein the first and second axis (8, 33a) are substantially horizontal.
