1. A fan assembly having a rotatingly driven hub, with radial fan blades that can be pivoted toward the hub housing, with a central stationary supporting neck, on which the hub housing is supported in an axially stationary and rotationally supported manner, and with an actuating drive for the fan blades, which has a linear drive with an actuating element inserted into the supporting neck and an actuator that can be axially displaced via the actuator, wherein an annular body that is stationary in relation to the hub housing is radially supported in relation to the actuator, which is connected to the fan blades that can be adjusted in terms of their pitch via drive elements that are engaged eccentrically in relation to the rotational axes thereof, characterized in that the actuator is formed by a support body on the supporting neck that is axially displaceable and is guided thereon in a non-rotating manner. |
