Device for generating directed fluid flow, particularly directed air flow by moving operative element with active surface in fluid, has support structure and rotary structure mounted relative to support structure

摘要

The device has a support structure (1), a rotary structure (5) mounted relative to the support structure about an axis of rotation (10) and an active element that is mounted on the rotary structure. An active element is operatively connected to the rotary structure and to the support structure. An independent claim is also included for a drive device for generating superimposed rotational movements of active elements.
