Turbine for a flow power plant

A turbine comprising:

• a hub body including a shaft for transmitting the torque generated by the turbine to a driven machine;
• a plurality of turbine blades carried by the hub body and rotatable about their longitudinal axes;
• an adjusting body in an interior of the hub body, arranged as a spherical link chain extending coaxially to the shaft and rotatable about a shaft axis of the shaft;
• and
• a guide rod chain for each of the plurality of turbine blades, comprising two guide rods, including a first guide rod having a first end linked to the adjusting body via a swivel joint and a second guide rod having a first end linked to a second end of the first guide rod via the swivel joint, and the first guide rod and the second guide each including a second end rotatably mounted on the hub body about the longitudinal axis of the respective blade;
• wherein the adjusting body comprises a drive pin and a smooth spherical shell having a uniform surface, and wherein at least the first guide rod is spherically shaped from a side view perspective.
