Abstract
The present invention generally relates to a runner unit of a tidal power plant, and more particular to a device for reversing a blade of the runner unit. The device according to the invention is lighter and more efficient with respect to known solutions which involve articulated mechanisms as it is based on an auxiliary servomotor including a reciprocating linear rack which acts on the blade to be reversed.
