INTERMITTENT AEROSOL DISPENSING VALVE |
摘要 |
A valve assembly can automatically dispense aerosol content from an aerosol container (12) at predetermined intervals without the use of electric power. A diaphragm (40) at least partially defines an accumulation chamber (36) that receives gas propellant from a portion of the can (12) during an accumulatio n phase. Once the internal pressure of the accumulation chamber (36) reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel (51), and thereby initiate a spray burst of the mai n active chemical. The diaphragm (40) assumes its original position when the pressure within the accumulation chamber (36) falls below a threshold pressu re.
