ABSTRACT:
A butterfly valve system has an air cylinder with an internal passageway with an axis. An air control assembly includes a plurality of similarly configured plates positioned within the passageway with shafts mounted for independent oscillation and supporting the plates. A rocker arm is secured to each shaft to oscillate the rocker arms and shafts and plates independently of each other whereby the flow of air may be selectively controlled to generate a vortex flow by a user manipulating the drivers to open and close four quarter quadrants of the cross section of the cylindrical passageway.
