Wind power plant

The invention relates to a wind power plant having at least one rotor (1), wherein the rotor (1) has at least two rotor blades (2), wherein each rotor blade (2) is rotatable about a substantially radially aligned adjustment axis (4), wherein at least one angle adjustment device (5) is provided for adjustment of the rotor blades (2), wherein the angle adjustment device (5) has at least one control disk (8) and at least two cam disks (9) interacting with the control disk (8), wherein each cam disk (9) is rotatably mounted about a rotation axis, and wherein the rotation axis of the respective cam disk (9) coincides, and is in particular superimposed, together with the respective adjustment axis (4) of the respective rotor blade (9). The noise development, the maintenance expense, and/or costs of a wind power plant are reduced in that the cam disks (9) are functionally effectively permanently coupled via at least one coupling element (18).
