[ The invention claimed is:] [1.] An aerosol dispensing apparatus for dispensing metered amounts of fluid material from a reservoir, the apparatus comprising a container defining a reservoir, and a dispensing valve; the dispensing valve comprising:a) a metering chamber body defining a metering chamber and having one or more metering chamber ports; andb) a stem allowing for slideable movement within the metering chamber body, the metering chamber body and stem forming a stem passage way connecting the metering chamber to the reservoir, the stem containing a dispensing passage and being attached to a sealing segment allowing for slideable movement over the one or more metering chamber ports, the sealing segment being moveable such that:i) in a first position the metering chamber is fluidically isolated from the dispensing passage; and the metering chamber is in fluidic communication with the reservoir through the one or more metering chamber ports and the stem passage way; andii) in a second position the metering chamber is in fluidic communication with the dispensing passage; and the metering chamber is fluidically isolated from the reservoir by the sealing segment occluding the one or more metering chamber ports and the stern occluding the stem passage way.
