Abstract
An aerosol dispenser including a nozzle chamber for holding fluid to be dispensed and a diaphragm forming at least a portion of the chamber and having an aerosol dispensing nozzle disposed therein. The chamber includes a nozzle region proximate the nozzle and a larger reservoir region interconnected to the nozzle region. There is a restrictive passage for introducing fluid from the reservoir region to the nozzle region and restricting backflow from the nozzle region to the reservoir region. A driver, typically a piezoelectric bender, is provided to drive fluid from the reservoir region to the nozzle region and from the nozzle region through the nozzle to create an aerosol spray.
