Abstract

A fluid flow control device that controls a flow of fluid within the flow control device has a flow path to convey the fluid. A cross-sectional area of the flow path varies along the flow path. At least a portion of the length of the fluid flow control device includes an active surface capable of influencing the fluid flow through the flow path to cause vortical motion of the fluid within the fluid pathway.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fluid flow control device, the fluid flow control device comprising:
 an inlet having a cross-sectional area;   an outlet having a smaller cross-sectional area than the inlet cross-sectional area; and   a body including an internal surface that reduces in cross-sectional area from the inlet to the outlet, wherein the internal surface of the body includes a twist that effectuates an acceleration in fluid flow.   
     
     
         2 . The fluid flow control device of  claim 1 , wherein the body further includes an outer surface configured as a cone. 
     
     
         3 . The fluid flow control device of  claim 1 , wherein the twist includes a combination helical and spiral curvature. 
     
     
         4 . The fluid flow control device of  claim 1 , wherein the internal surface conforms to a logarithmic curve, the radius of the logarithmic curve measured at equiangular radii unfolding at a constant order of growth. 
     
     
         5 . The fluid flow control device of  claim 1 , wherein the twist is a volute. 
     
     
         6 . The fluid flow control device of  claim 1 , wherein the twist is a whorl. 
     
     
         7 . The fluid flow control device of  claim 1 , wherein the twist is a logarithmic helix spiral. 
     
     
         8 . The fluid flow control device of  claim 1 , wherein at least a portion of the internal surface conforms to the external or internal configuration of the shell of the phylum Mollusca. 
     
     
         9 . The fluid flow apparatus of  claim 1 , wherein the outlet generates a narrow vortical steam. 
     
     
         10 . The fluid flow device of  claim 1 , wherein the outlet generates a diverging vortical stream. 
     
     
         11 . The fluid flow device of  claim 1 , wherein the fluid flow is transversely diverted with respect to the received fluid. 
     
     
         12 . A fluid flow control device, the fluid flow control device comprising:
 an inlet having a cross-sectional area;   an outlet having a larger cross-sectional area than the inlet cross-sectional area; and   a body including an internal surface that reduces in cross-sectional area from the inlet to the outlet, wherein the internal surface of the body includes a twist that effectuates a deceleration in fluid flow.   
     
     
         13 . The fluid flow control device of  claim 12 , wherein the body further includes an outer surface configured as a cone. 
     
     
         14 . The fluid flow control device of  claim 12 , wherein the twist includes a combination helical and spiral curvature. 
     
     
         15 . The fluid flow control device of  claim 12 , wherein the internal surface conforms to a logarithmic curve, the radius of the logarithmic curve measured at equiangular radii unfolding at a constant order of growth. 
     
     
         16 . The fluid flow control device of  claim 12 , wherein the twist is a volute. 
     
     
         17 . The fluid flow control device of  claim 12 , wherein the twist is a whorl. 
     
     
         18 . The fluid flow control device of  claim 1 , wherein the twist is a logarithmic helix spiral. 
     
     
         19 . The fluid flow control device of  claim 1 , wherein at least a portion of the internal surface conforms to the external or internal configuration of the shell of the phylum Mollusca. 
     
     
         20 . The fluid flow apparatus of  claim 1 , wherein the outlet generates a narrow vortical steam. 
     
     
         21 . The fluid flow device of  claim 1 , wherein the outlet generates a diverging vortical stream. 
     
     
         22 . The fluid flow device of  claim 1 , wherein the fluid flow is transversely diverted with respect to the received fluid.
