The invention relates to a wave power assembly having a hull and a linear electric generator. The rotor (7) is, by means of connection means (4), connected to the hull so that lifting force is transferred from the hull to the rotor (7). Spring means (11b) exerts a force on the rotor (7) that is counter-directed the lifting force. According to the invention, the spring means (11b) is arranged to, at a motion amplitude corresponding to 50 % of the maximum length of stroke of the rotor (7), exert a force, the size of which varies by a factor of 2,5 as a maximum. The invention also relates to a wave power plant built up from wave power assemblies according to the invention. Furthermore, the invention relates to a use of the wave power assembly and a method for the generation of electric energy.
L'invention concerne un ensemble houlomoteur comprenant une coque et un générateur électrique linéaire. Un rotor (7) est connecté, à l'aide de moyens de connexion (4), à la coque de sorte qu'une force de levage est transférée de ladite coque au rotor (7). Des moyens de ressort (11b) appliquent une force sur le rotor (7) contrecarrant la force de levage. Selon l'invention, les moyens de ressort (11b) sont agencés afin d'appliquer une force, selon une amplitude de déplacement correspondant à 50 % de la longueur maximum de la course du rotor (7), dont la grandeur varie selon un facteur maximum de 2,5. L'invention concerne également une centrale houlomotrice construite à partir des ensembles houlomoteurs de l'invention. L'invention concerne, en outre, l'utilisation d'un ensemble houlomoteur et un procédé de production d'énergie électrique.
