    Abstract: PROBLEM TO BE SOLVED: To provide a metering device of an inhaler including a pressurized source of medicated fluid and a measuring chamber communicated with a pressurization supply source for a liquid.
    SOLUTION: An aerosol generator includes: a flow passage 27 having an inlet 29 and an outlet 31; a heater 33 disposed relative to the flow passage for heating the flow passage; a supply source 37 of material to be volatilized in communication with the inlet of the flow passage; a valve 35 to open and close communication between the source of material and the inlet of the flow passage; and a pressurization structure 39 for causing material in the source of material to be introduced into the flow passage when the valve is in an open position. The aerosol generator further includes a source of power 41 for operating the heater 33 and the valve 35, and a control device 43 for controlling supply of power from the source of power to the heater 33 and the valve 35. The metering device in an inhaler 21 includes a pressurized source of medicated fluid and a metering chamber configured to deliver a predetermined volume of fluid to a heated flow passage in the inhaler.
