形状としたものである。According to the present invention, a driving liquid is introduced into a swirl flow generating container of a fluid transfer device from a tangential direction of a cylindrical portion to form a swirl flow, and a negative pressure is generated in the container by the swirl flow. It is generated and sucks a fluid such as gas from the fluid suction pipe and ejects the fluid from the fluid ejection opening facing the outside of the generation container, and the fluid ejection opening has the special shape as described above. It is a thing.

向上させことができた。That is, in the present invention, the shape of the ejection opening is not the same from the fluid inflow side to the outflow side as in the conventional device, but the diameter of the opening is the narrowest in the central portion in the fluid movement direction. It is designed to continuously expand in a curved shape toward the fluid inflow side and the fluid outflow side, and as a result, the energy efficiency and gas transfer efficiency of the fluid transfer device can be improved.
