Abstract
The present disclosure relates to aerosol delivery devices. The aerosol delivery devices include mechanisms configured to deliver an aerosol precursor composition from a reservoir to an atomizer including a heating element to produce a vapor. A pressure controller may control dispensing of the aerosol precursor composition from the reservoir based on a pressure differential between a first pressure within the reservoir and a second pressure proximate the atomizer. The first pressure within the reservoir may be substantially equal to atmospheric pressure. Alternatively, the first pressure within the reservoir may be greater than atmospheric pressure.
