Abstract
The present invention relates to metering valves and methods for repeatedly delivering a precise amount of a pressurized fluid such as an aerosol. Each metering valve is configured such that the metering chamber exists only upon actuation of the valve stem to dispense a dosage. Thus, the metering chamber is created, filled with aerosol formulation, and emptied during the brief moment that the valve stem is depressed and subsequently released by the user to dispense a dosage. Alternative embodiments of the present invention also include mechanisms for pressure filling an aerosol container through such a metering valve.
