| 摘要 |
The invention relates to an apparatus for exchanging kinetic energy between a flowing fluid and a moveable structure connected to the apparatus, the apparatus comprising a channel enclosed by a channel wall connected with the structure, the channel wall being adapted to guide the fluid, at least two substantially identical blades extending within the channel, being moveable within the channel and being connected to an energy converter coupled with the structure, the blades being adapted to perform a recurrent movement in the flow direction with the main plane of the blades substantially perpendicular to the flow direction and against the flow direction with the main plane of the blades substantially parallel to the flow direction, and guides extending from the channel wall into the channel for supporting the blades at a distance from the channel wall during the movement of the blades. |
