    Abstract: The invention relates to wind turbines with variable rotor blades whose pitch angle can be adjusted, wherein an adjustment unit for adjusting the pitch angle of a wind turbine rotor blade with a pivot bearing comprising at least two coaxial bearing rings that are rotatable against each other, at least one adjustment actuator for rotating the two bearing rings against each other, and a supply unit for supplying the adjustment actuator with energy, wherein the at least one adjustment actuator and the supply unit are disposed on opposite sides on a plate-shaped adjustment drive carrier part which is directly or indirectly rotatably connected with one of the bearing rings and comprises a rotatable support bearing for the rotatable support of the adjustment actuator on the carrier part. The supply unit is connected with the adjustment actuator by at least one pressurized-media channel passing through the support bearing.

    Abstract: The present invention relates to wind turbines with variable rotor blades whose pitch angles are adjustable. An adjustment unit is provided for adjusting the pitch angle of the rotor blades with a pivot bearing comprising at least two coaxial bearing rings that are rotatable against each other, at least one adjustment actuator for rotating the two bearing rings, and a supply unit for supplying the adjustment actuator with energy, whereby the adjustment actuator and the supply unit are disposed on opposite sides on a plate-shaped adjustment drive carrier part which is rotatably connected with one of the bearing rings and comprises a rotatable support bearing for the support of the adjustment actuator. A least one part of the supply unit is rotatably mounted on the carrier part such that the supply unit or its rotatably mounted part and the adjustment actuator are jointly rotatably mounted and/or swivel-mounted on the carrier part.
