Patent ID: 8631827

Claim:
A fluid flow control apparatus for altering a flow of fluid, the fluid flow control apparatus comprising: an inlet that receives fluid from a fluid source; an outlet that expels the fluid received from the fluid source; and; a flow path situated between the inlet and the outlet and within a body of the fluid flow controller apparatus, the flow path including an area of constriction in which the diameter of the body is reduced, the flow of fluid induces a vortex having an axis of rotation disposed substantially transversely to the central axis of the inlet, the flow path further including an area of expansion in which the diameter of the body is increased, a centerline of the area of expansion being colinear with the centerline of the area of constriction, the flow path conveying the fluid from the inlet to the outlet, and wherein at least a portion of the length of the body includes an internal surface area that induces a rotational motion in the fluid as the fluid traverses the flow path thereby resulting in a vortical motion in the fluid as the fluid is expelled from the outlet.
