Abstract
A fluid-driven power device is provided, including two fixed plates and a plurality of vanes. The two fixed plates are spaced out a distance, and respectively have two inner surfaces face each other, wherein a central axis passes through centers of the two inner surfaces. The vanes are provided between the two fixed plates and around the central axis. Two connected ends of each vane are respectively connected to the inner surface of the two fixed plates. Each vane forms a spiral twist, and the torsion angle of each of the vanes is changed from a central portion between the two connected ends toward the two connected ends in a symmetrical manner. Whereby the vanes can rectify the fluid, and prevents the output fluid from forming turbulence which interferes with rotation of the power device. Therefore, the rotation speed and efficiency of the power device will be further improved.
