Abstract
Selon l'invention, un cylindre allongé (10) est entièrement immergé, dans une position verticale, juste au-dessous du niveau d'eau moyen, par exemple de l'océan, et présente une longueur, selon les ondes de surface de longueur d'onde préétabli, telle que le sommet du cylindre subit des variations de pression relativement importantes en réponse à des ondes de passage supérieur, tandis que le bas du cylindre est soumis à une pression presque stable sensiblement indépendante des ondes de passage supérieur. La différence de pression sur la longueur du cylindre est utilisée pour provoquer des mouvements relatifs entre le cylindre et l'eau adjacente, et lesdits mouvements relatifs sont utilisés pour actionner un piston (12) d'un convertisseur énergétique. Le cylindre peut être creux et installé à un emplacement fixe pour provoquer des mouvements de l'eau à travers le cylindre; ou le cylindre peut se déplacer dans l'eau relativement à un transducteur fixe. Dans une version du cylindre mobile, le transducteur est monté amovible sur un flotteur en place fixe disposé à l'intérieur du cylindre mobile. Dans une seconde version, le transducteur est monté amovible sous le cylindre mobile, sur le plancher océanique, et le cylindre est couplé au transducteur.
