Set on the axle (L), a support (E) ensures the fastening of the end-plates of a series of double-acting actuating cylinders (D). The rods of the latter are in a ball-jointed connection with the body (A) in order to offer the latter a maximum degree of freedom in space. A rigid arm (C) is set on one side of the wheel (F) and held on the other side, in a pivot connection, on a U-shaped section piece (B). Having a circular satellite motion, the latter rotates with the wheel (F) while sliding over a peripheral region of the body (A). When the wind acts on the body (A), the latter pivots with the section piece (B) and pushes the rods of the actuating cylinders (D). Having a circular satellite motion, the section piece (B) rotates while sliding over a peripheral region of the body (A), thus changing the fulcrum of the moment of the resultant force of the wind (the pivot connection of the section piece (B)) which is applied to the body (A). The rods of the actuating cylinders (D) will consequently be pulled and pushed, while having a cyclical translational motion. Set on the axle (L), a nacelle (J) primarily contains a hydraulic motor (H) and an electric generator (G), which can be coupled via a speed-increasing gear. During the reciprocal motions of the pistons of the actuating cylinders (D), a set of valves ensures a one-way flow of hydraulic fluid in the “go and return” hydraulic circuits, whether by pulling or by pushing. The “go and return” hydraulic circuits are, moreover, linked to the hydraulic motor (H). In order to allow the system (SCEE) to be held facing the wind and to pivot on the mast (1), its orientation can be ensured by a tail vane (K) fastened, via a support, to the nacelle (J). |
