PURPOSE: To improve the directional properties of the flow of fluid by a method wherein at least one louver is formed of a resilient material being changeable of the flow direction and the velocity of flow of fluid through expansion and contraction operation of a thread.
CONSTITUTION: Louvers 4 and 5 formed of a resilient substance are fixed to a fixed shaft 6 and the direction of the flow of fluid is changeable through deformation of a louver through pull or slackening of a thread 8 attached to the lower parts of the louvers 4 and 5. Arms 11 and 12 connected to an electric motor 9 transmit operation to run the electric motor 9 to an X-arm 10. Since the X-arm 10 is rotated, the rotation is changed into operation to pull and restore the thread 8 by a distance between the center of the X-arm 10 and the end of the X-arm 10, whereby no malfunction occurs. Since the louver formed of a resilient substance has a strong and a weak part, the louver formed of a resilient substance deformed through operation to pull and restore the thread is formed in a shape where incurring of a pressure loss is uniformly reduced to a lowmost value. This constitution and method enable fluid to produce a flow the direction and the velocity of flow of which are kept at a target value, reduces incurring of a pressure loss, and decreases the generation of noise.
