Abstract

PURPOSE: To provide an energy converter whose constitution is simple and which is unlikely to be damaged and produces a constant output, by placing a vibration system in a flow so that the system vibrates in parallel with the flow and by changing the energy of the flow into the reciprocation energy of the vibration system.
CONSTITUTION: A pressure reception plate 1, which receives the pressure of a fluid, is supported on one end of a strut 2 and placed in the fluid. The other end of the strut 2 is secured. The pressure reception plate 1 and the strut 2 constitutes a vibration system. The natural frequency of the system can be selected by appropriately setting the length and thickness of the strut 2. The the vibration system performs reciprocation at the period determined by the natural frequency, centering a position tilted to the downstream side. For that reason, an appropriate device is attached to an optional point of the vibration system, for example, a point 3 to take out the reciprocation energy of the vibration system. Since the vibration system is simply composed of the pressure reception plate 1 and the strut 2, the system is unlikely to be damaged. In addition, a constant output is obtained because of the natural frequency.
