Patent ID: 8616115

Claim:
A brewing apparatus comprising: a fixed axis; a fixed frame; a reversible drive; a number of movable driven members, all of the movable driven members coupled to the drive to oscillate about the fixed axis, to move radially with respect to the fixed axis, or combinations thereof, the movable driven members including: a first piston mounted for moving radially with respect to the fixed axis to eject a material to be brewed when brewed; a second piston mounted for moving radially with respect to the fixed axis to compress the material to be brewed before brewing; a first movable body comprising a hollow body defining a brewing chamber and fitted to the frame to perform an oscillating first movement with respect to the frame and about the fixed axis; a second movable body which is defined by said first piston and is fitted to the hollow body to perform the first movement with the first movable body, and to perform, with respect to the first movable body, a second movement along the brewing chamber and radially with respect to the fixed axis; a third movable body which is defined by said second piston and is fitted to the frame to perform a radial third movement with respect to the fixed axis, so as to be inserted into and expelled from the brewing chamber when the first movable body assumes a given position about the fixed axis; and a movable control unit comprising movable control means fitted to the frame to oscillate about the fixed axis; and fixed control means which cooperate with the movable control means to control the movements imparted by the drive to the other movable driven members.
