Apparatus to prepare beverages

A brewing apparatus (1) for preparation of a beverage by brewing an ingredient (32), that comprises:

• a support frame (2),
• a brewing chamber (3) having a wall (3a) to receive said ingredient (32), the brewing chamber (3) having a substantially vertical axis (A-A);
• a first piston (7) and a second piston (9), said second piston (9) including a head (8) and a rod (9b), wherein said brewing chamber (3), said first piston (7) and said second piston (9) are movable with respect to said support frame (2);
• a liquid inlet provided in one of said first piston (7) or said second piston (9), and a liquid outlet provided in either the first piston (7) or second piston (9) that is not provided with the liquid inlet, said second piston (9) being co-axially movable with said chamber (3) and within said chamber (3);
• and
• a discharge device (21) for discharging the ingredient (32) after brewing,
• wherein said discharge device (21) is pivotally movable around a pin (22) with respect to said brewing chamber (3) in a plane perpendicular to said axis (A-A), wherein said discharge device (21) for discharging the ingredient (32) after brewing is provided with:
• a central part (21b) that is mounted pivotally on said pin (22), said pin (22) being connected to said brewing chamber (3);
• a working portion (21a, 30, 31) to remove the ingredient (32) from the head (8) of the second piston (9);
• and a projecting portion (21c) that extends from said central part (21b) and that is housed in a guide (23), said guide (23) extending along said apparatus (1), parallel to the said axis (A-A) of the brewing chamber (3) and being fixed to the support frame (2), wherein a portion (23b) of said guide (23) has a double curved shape and is configured to provide a double rotation of the working portion (21b) around said pin (22), wherein said chamber (3) and said second piston (9) are movable along a path according to said axis (A-A) from a bottom position (Hmin) to a top position (Hmax), said path including a discharge position (Hdis) between the bottom position (Hmin) and the top position (Hmax) to discharge the ingredient (32) from said chamber (3) after brewing the ingredient, said positions (Hmin, Hmax and Hdis) having a height between an upper rim (3b) of said chamber (3) and a lower base (2a) of the support frame (2), wherein said chamber (3) and said rod (9b), when in said discharging position (Hdis), are both spaced from said bottom position (Hmin), wherein a length (L4) is the difference between the height at the discharge position (Hdis) and the height at the bottom position (Hmin), and wherein the length (L4) is greater than the height of the bottom position (Hmin).
