Special Session on Real-Parameter Optimization at CEC 05

A fluid flow valve is disclosed for sequentially switching an incoming fluid stream through each of a plurality of outlet ports. An impeller is disposed for angular rotation within the valve and turns in response to the flow of fluid. The impeller is connected to a rotor by means of a planetary gear train. The rotor operates a cam which opens one segment of a multi-segmented plate associated with the outlet ports, thereby allowing fluid flow through the selected outlet ports.
