Windmotor.

摘要

Windmill with rotor blades (6) each of which, at an end thereof, is hinged to an end plate (7) mounted on a rotatable shaft (3) of the windmill, by means of a ball joint (10). A connecting bar (11) is hinged between an associated rotor blade (6) and the end plate (7), also by means of ball joints (12 and 13), at distances from the ball joint (10) which connects the associated rotor blade (6) to the end plate (7). On rotation of the rotor blades (6) by the wind, the connecting bar (11) limitates the deviation of the rotor blades (6) in the direction o the wind and smoothly copes with sudden changes in wind force.
