Fluid transferring apparatus imitating flapping movement of bees.

摘要

The present invention provides a fluid transferring apparatus which achieves a second-dimensional flow of fluid with high efficiency and at low noise by imitating a Weis-Fogh mechanism with use of a simple mechanism. In the fluid transferring apparatus, a wing assembly X comprising a predetermined number of plate-like wings 4 is provided in a transverse direction of a flow passage 2. The wing assembly X is supported by a link 5 of a crank mechanism Y1 which consists of a crank 6 rotated by a motor, a slider 8 slidable in a direction orthogonal to a direction of a flow in a flow passage 2 , the link 5 coupling the crank 6 with the slider 8, so that rotational motion of the crank 6 is transmitted to the slider 8 as a reciprocal movement. While an angle of attack of each wing 4 is changed by the oscillating action of the link 5, each wing 4 is moved in a transverse direction of the flow passage 2 as the link 5 is reciprocated, thereby achieving transfer of fluid. <IMAGE>
