Abstract

A device for regulating the pitch of the rotor blades (6) of a wind motor automatically in response to high wind loads on the blades includes a respective crank lever (14) attached to the shaft (12) of each variable pitch blade (6) and connected through a cam linkage (32, 33) to an arm (34) of an axially displaceable collar (36) which is loaded by a thrust spring (46). A piston (52) is connected to the collar and slides within a cylinder (38) to dampen vibration of the blades about their pitch axes. <IMAGE>
