摘要：A valve assembly can automatically dispense aerosol content from an aerosolcontainer at predetermined intervals without the use of electric power. A diaphragm atleast partially defines an accumulation chamber that receives gas propellant from a
portion of the can during an accumulation phase. Once the internal pressure of theaccumulation chamber reaches a predetermined threshold, the diaphragm moves,carrying with it a seal so as to unseal an outlet channel, and thereby initiate a spray burstof the main active chemical. The diaphragm assumes its original position when thepressure within the accumulation chamber falls below a threshold pressure.
