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.
