Abstract: Wind engine device consisting of a wind power engine (2) and means (3) to increase the wind velocity in the direction of the wind power engine (2) when the wind velocities are low, whereby these means (3) contain at least a first wind guiding element (5) which narrows in a conical manner according to the direction in which the wind (W) blows towards the wind power engine (2), characterized in that this device (1) contains means (4) which make it possible to diminish the wind velocity, the wind force respectively, on the place where the wind power engine (2) is situated, which contain a second wind guiding element (9) which joins the exit (7) of the first element and which widens in a conical manner according to the direction in which the wind blows on the one hand, and adjustable means (10) to move the wind power engine (2) and the second wind guiding element (9) in relation to one another, such that the wind power engine (2) slides in further or less further in the second wind guiding element (9).

Abstract: Improved wind-engine, comprising a frame (1) and several wind devices (2) mounted on different stages, one above the other on transversal parts (4) of this frame (1) with at least one separation wall (5, 6) mounted on the frame (1), between the wind devices (2) situated one above the other.

Abstract: A wind-engine of the type consisting of several wind devices rotatably mounted at several independent stages, which comprises the combination of vertical props (1) disposed within a circle (4); at each stage (2), crossbeams (5) connected, on one hand, to the vertical props (1) and meeting, on the other hand, at the center of the said circle (4); a vertical axis (7) situated at the center of the said circle (4) and, at each stage, a wind device rotatably mounted about the said vertical axis.
