The invention concerns an apparatus for the production of energy from currents in bodies of water with a surface towards the atmosphere. The apparatus comprises an axial turbine (1) with blades with adjustable pitch. The turbine (1) is secured to a housing and the housing (2) is secured to a foundation (14) that furthermore is founded to the seabed (10) below the flowing body of water. The apparatus is completely submerged below the surface of the body of water, and the turbine blades can be twisted at least 180~ to allow the turbine (1) to rotate the same direction regardless of the direction of flow of the body of water. Furthermore the invention describes a method for the installation of such appa- ratuses and a foundation for the installation.
L'invention concerne un appareil destiné à la production d'énergie à partir de courants dans des corps d'eau ayant une surface en direction de l'atmosphère. L'appareil comprend une turbine axiale (1) pourvue de lames équipées d'un pas réglable. La turbine (1) est fixée à un boîtier et le boîtier (2) est fixé à une fondation (14) ayant sa fondation dans le fond (10), au-dessous du corps d'eau en écoulement. L'appareil est complètement submergé au-dessous de la surface du corps d'eau et les lames de la turbine peuvent être tournées à au moins 180·, de manière à permettre à la turbine (1) de tourner dans la même direction, sans tenir compte de la direction d'écoulement du corps d'eau. De plus, l'invention concerne un procédé d'installation de tels appareils et une fondation destinée à l'installation.
