    Abstract: A vertical axis wind turbine includes a support axis and a wind wheel. The wind wheel includes a rotation base, plural rotation stand sets, plural deflection structures, plural blades, and plural deflection-limiting structures corresponding to the plural blades. The rotation base is rotatably disposed on the support axis. The plural rotation stand sets may define a rotation plane. A first end of each rotation stand set is fixedly disposed on the rotation base. Each blade is pivotally coupled to a second end of the corresponding rotation stand set through the corresponding deflection structure. Consequently, an angle of attack of the blade in an airflow is correspondingly adjusted. When one of the plural blades is deflected, the corresponding deflection-limiting structure generates a first rotational torque in a first rotating direction or a second rotational torque in a second rotating direction so as to rotate the rotation base.

The pressure surfaces can be pivoted around axes arranged parallel to and spaced from the rotor axis, in particular for the production of energy from tidal currents of the sea. The pressure surfaces are attached to the pivot axes in a pendulum-like manner and stop elements for the pressure surfaces are arranged in the radial planes between the pivot axes and the rotor axis. The pivot axes of the pressure surfaces are attached by their ends to support disks radially directed towards the rotor axis. The support disks are located at the ends of the rotor axis. The support disks are embodied in at least a double-walled manner. Alternatively or additionally each pressure surface is embodied at least in a double-walled manner.
