Hooded wind power engine

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).
