Abstract: A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives aerosol content from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it a leg so as to unseal a valve stem, and thereby initiate a spray burst. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure. A barrier prevents the aerosol container from resupplying the accumulation chamber at a high rate during the spray phase, preferably due to a textured interface between the barrier and a passageway in which it is housed.
