APPARATUS, SYSTEM AND METHOD FOR GENERATING AN AEROSOL

This invention provides an apparatus (100) for generating an aerosol and/or a vapour in an inhaler device (200), the apparatus (100) comprising: a reservoir (10), such as a volumetrically variable reservoir, for storing a supply of a liquid (L); a heating system (20) fluidly connected with the reservoir (10) for receiving the liquid and configured to heat the liquid to generate the aerosol and/orvapor therefrom; a pumping system (30) configured to pump the liquid (L) from the reservoir (10) to the heating system (20); and a valve arrangement (40) for regulating flow from the pumping system (30) to the heating system (20), the valve arrangement (40) having at least one valve (41 ) which is configured to transition from a closed position to an open position for transmitting the liquid (L) from the pumping system to the heating system. The invention also provides an inhaler device (200) which includes the apparatus (100), as well as a system (1000) for generating an aerosol and/or a vapor from a liquid, the syst
