METERING VALVE FOR A METERED DOSE INHALER |
摘要 |
A metering valve (14) including a housing (18) that serves to house the various components of the metering valve (14). The top portion of the housing (18) attaches to the aerosol container (12). A valve (22) is seated within the valve housing (18) and in turn provides a housing for a valve stem (24). The housing (18), the valve body (22) and a diaphragm (20) may be aligned so that, together, they form an aperture. The metering valve (14) includes an interior chamber (38), a portion of which is occupied by a valve stem (24). One or more ports (46) provide fluid communication between the interior chamber (38) and the aerosol container (12). A spring (48) may serve to bias the valve stem (24) toward the resting position.
