ABSTRACT:
A pressurized spray system. The spray system has a flow path through which contents must pass to be dispensed from the system to the atmosphere. By maintaining the proper proportions of restrictions in the flow path to the spray nozzle exit orifice, a relatively constant mean particle size distribution may be obtained throughout the life of the spray system as the pressure decays.
