More Information
Summary:An valve assembly is provided that automatically dispenses aerosol content from a can at predetermined intervals. 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 flexes to initiate a spray phase, during which the aerosol content is delivered from the accumulation chamber to the ambient environment. A rotatable pawl provides resistive pressure and control of diaphragm movement.
