Abstract
A fluid transfer apparatus includes a spiral pipe that is formed by an elastic tube wound in a spiral manner, and a fluid to be transferred flows in the spiral pipe. The fluid transfer apparatus further includes a speaker that is configured to generate a pressure wave in a working fluid in the tube that is a medium, and the pressure wave causes a change of the cross-sectional area of a flow channel of the tube.
Claims12
A fluid transfer apparatus, comprising:
- a spiral pipe which is formed by an elastic tube wound in a spiral manner and in which a fluid to be transferred flows;
- and
- a speaker configured to generate a periodic pressure wave in a working fluid that flows in the tube and that serves as a medium of the pressure wave, the pressure wave causing a change of a cross-sectional area of a flow channel of the tube, which is an area of a cross section of the tube that is perpendicular to an axial direction of the tube, the change of the cross-sectional area of the flow channel of the tube being a periodic increase and decrease of the cross-sectional area.
