Abstract: A duocone spray nozzle having two concentric peripheral orifices which will produce two hollow spray cones, one inside the other. Each orifice size is varied by employing its own spring and each spring acts independently and is compressed under its own pressure drop. The springs are designed so that the inner spring will open the inner orifice at a pressure drop which is lower than the pressure drop occurring at the outer office. Therefore, the inner spray cone occurs before the outer spray cone. When the pressure drop at the inner orifice exceeds a predetermined value, the outer orifice opens and after this occurs there will be two spray cones. A hold structure aids in separating the two spray cones.
