Abstract:  
This invention relates to a constant flow control device for a pressure pot shot peening machine, Such structures of this type, generally assure that the air flow and the pressure drop through the pressure pot shot peening nozzle remain independent of uncontrolable upstream conditions, thus assuring constant velocity of the shot stream regardless of shot delivery hose routing or wear.
