Abstract
A fluidic pulse generator system includes two fluidic diverter valves that are both controlled by a single fluidic pilot valve. The fluidic pilot valve and the two fluidic diverter valves are each adapted to receive a flow of pressurized fluid. The flow of pressurized fluid through the fluidic pilot valve is controlled in response to pressurized fluid flow through a control valve. In turn, the flow of pressurized fluid through the two fluidic diverters valves is simultaneously controlled in response to the flow of pressurized fluid through the fluidic pilot valve.
