A high-speed, high pressure rotary valve is provided comprising a valve body, a valve element which includes a plurality of passageways therethrough that is configured to be rotatably disposed within the valve body, and means for rotating the valve element within the valve body whereby a single rotation of the valve element results in the creation of multiple discrete flow paths through the rotary valve and multiple valve actuation cycles.

What is claimed is: 1. A rotary valve comprising: a. a valve body; b. a valve element rotatably disposed within said valve body, said valve element having an axis of rotation and a plurality of flow passageways therethrough, wherein all of said flow passageways are coplanar and substantially perpendicular to said axis of rotation; and c. means for continuously rotating said valve element within said valve body. 2. The rotary valve of claim 1 wherein said valve element is a ball having a circumference bisected by said axis of rotation. 3. The rotary valve of claim 2 wherein each of said passageways are equally spaced about said circumference. 4. The rotary valve of claim 1 wherein each of said passageways is linear. 5. The rotary valve of claim 1 wherein each of said passageways intersects at said axis of rotation. 6. A rotary valve comprising: a. a valve body having a flow passageway for a flow of fluid; b. an upstream valve seat and a downstream valve seat provided in said flow passageway; c. a valve ball, having an axis of rotation, rotatably disposed in said valve body between said upstream and downstream valve seats; d. said valve ball having a plurality of flow apertures therethrough, wherein all said flow apertures intersects at said axis of rotation; and e. means for continuously rotating said valve ball within said valve body. 7. The rotary valve of claim 6 wherein said flow apertures are coplanar. 8. The rotary valve of claim 6 wherein said flow apertures are equally spaced about a circumference of said valve ball. 9. The rotary valve of claim 6 wherein said flow apertures are equally sized. 10. The rotary valve of claim 6 wherein said flow apertures are configured such that said flow of fluid is discontinuous. 11. The rotary valve of claim 6 wherein said flow apertures are configured such that said flow of fluid is continuous. 12. The rotary valve of claim 6 wherein said flow apertures alternatively communicate with said flow passageway as said valve ball rotates about said axis of rotation. 13. A method of producing flow perturbations comprising: a. providing a valve body having an inlet and an outlet; b. providing a valve element, with an axis of rotation, rotatably disposed within said valve body between said inlet and said outlet, c. adapting said valve element to be continuously rotated within said valve body; d. providing said valve element with a plurality of passageways therethrough, wherein all of said passageways are coplanar, substantially perpendicular to said axis of rotation, and intersect at said axis of rotation; and e. providing means for rotating said valve element within said valve body whereby each 360 degree rotation of said valve element creates a plurality of flow perturbations.
