The second bearing is mounted between the second portion and a lever means having a rotary point at the supporting structure. When operating the at least one linear actuator, the second portion is moved axially, leading to an angular movement of the lever means causing a change of the pitch of a blade, and when operating the at least one linear actuator, a force is generated that acts upon the non rotary element, so that the rotor shaft is unaffected by the force. Also, a fan comprising the device is disclosed. | 2011-02-17 |
