Capsule, system and brewing device for the preparation of a beverage. The capsule comprises a circular or conical lateral wall (2), an inlet wall (3) and an outlet wall (4) forming a hollow body (5) where a brewing product is contained, said hollow body (5) of the capsule having a central axis (A). At least one portion of the inlet wall (3) extends along an ellipse curve (E) defined by the projection of a circumference (C), having a diameter substantially equal to the maximum diameter (Dmax) of the lateral wall (2) of the capsule, lying on a plane (&Rgr;') inclined of an angle (a) with respect to a plane (P) perpendicular to the central axis (A) of the capsule, said planes (P) and (&Rgr;') intersecting at an axis (z), on a plane that is perpendicular to plane (P) and that contains said intersection axis (z) or an axis parallel to it. |
