ABSTRACT:
Several projected stripes, extending at regular intervals along the direction of fluid flow, are provided over the entire outer surface of a conical diaphragm except its outermost edge and neighboring section, and this diaphragm is set in a fluid-flow path with its outermost edge in tight contact with the wall of the fluid-flow path. The set of projected stripes not only arranges uniform flow of fluid but also prevents the diaphragm from being deformed under the fluid pressure.
