Abstract

A fluid forcing device comprising many rotatable slender elements that converts mechanical energy into fluid energy by mechanically arranging and maintaining, at all time, the rotatable slender elements in a predetermined wave form and by mechanically moving the wave form in a direction normal to the rotation of the elements by an improved drive comprising two fluted rollers. The new drive reduces the weight and complexity of the entire fluid forcing device and renders it more mechanically rigid and less vibration prone.
