Apparatus with rotating eccentric masses for developing unidirectional inertial forces

An apparatus for developing inertial forces, the resultant of which is a unidirectional force, said apparatus being characterized in that it comprises at least two masses (M) or pairs of masses (M), each of which rotates on a generic plane and along a closed path that is parallel and adjacent to that of the other mass or pair of masses that moves in the opposite direction and is symmetrical with respect to a vertical axis coinciding with the axis of symmetry of the path of said masses (M), said path being comprised between a minimum path and a maximum path, both comprised in an outer circumference (C1) having a radius (R1) and a diameter (D1) that is perpendicular to the axis of symmetry of the path of the masses (M), as well as a centre (O) that coincides with the centre of rotation of the masses (M);

• said minimum path being defined by a circumference (C3) having a radius (R3) equal to 1/10 of the radius (R1) and a centre (O′) set on the axis of symmetry of the path of the masses and tangential to the centre of the circumference (C1);
• said maximum path being defined by two minor circumferences of radius (RK)≦¾ (R1), each having its own centre on the diameter (D1) of the circumference (C1) and being tangential thereto at the end of the latter, by joining:
• a stretch of horizontal chord that joins the two points of tangency with the two minor circumferences;
• an arc of the right-hand minor circumference;
• a top arc of the circumference (C1);
• and an arc of the left-hand minor circumference, said latter arc being symmetrical to the first.
