Apparatus for delivering a predetermined amount of a pressurized fluid. |
摘要 |
<p>The metering valve is configured such that the metering chamber (60) exists only upon actuation of the valve stem (24) 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 includes means for pressure filling an aerosol container through such a metering valve.</p> |
