Abstract
A fluid transferring apparatus achieves a two-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 comprised of a predetermined number of plate-like wings is provided in a transverse direction of a flow passage. A wing assembly X is supported by a link of a crank mechanism which is constituted of a crank rotated by a motor, a slider slidable in a direction orthogonal to a direction of a flow in a flow passage and the link coupling the crank with the slider, so that rotational motion of the crank is transmitted to the slider as a reciprocal movement. While an angle of attack of each wing is changed by oscillating action of the link, each wing is moved in a transverse direction of the flow passage as the link is reciprocated, thereby achieving transfer of fluid.
