Abstract: The device is intended to adjust the pitch of blades or propellers which are articulately coupled by means of end supports inside radial bearings which are solidly joined to a rotating head-piece of a wind generator. This adjustment may be performed either actively or passively. It is characterized in that the rotating head-piece incorporates a linear actuator (1), such as a cylinder, the shaft of which is connected to a crosspiece (14), the latter being associated with intermediate mechanisms connected to the end supports (7) of the blades (6) so as to vary the pitch thereof when the crosspiece (14) moves, being driven by the shaft of the cylinder.
