Description

A control device for a pumping system incorporating fluidic devices has an air inlet leading to a convergent/divergent nozzle producing supersonic flow. A compressive shock wave is produced just upstream of an intake of a diffuser. An outlet may go to vent or a jet pump. Spaced oblique compressive shock waves can be produced in a device with an Oswatitsch intake. The device can be used in a pumping system for example one incorporating a reverse flow diverter.
