1. An aerosol metering valve system for dispensing a metered dose of product comprising:
a metering chamber defined by a side wall, a top wall and a bottom wall,
a charging port extending from the bottom wall of the metering chamber,
a releasing stem extending from the top wall of the metering chamber, wherein the releasing stem is connected with a stem block extending towards the charging port,
a piston arranged in the metering chamber and moveable in the metering chamber, and
a piston spring arranged in the metering chamber, resting with its one end against the piston and exerting pressure on the piston towards the charging port,
wherein
there is a charging channel arranged coaxially in the metering chamber,
wherein the piston tightly surrounds the charging channel,
wherein the charging channel has a charging opening closed by a closure and connecting the charging channel with a propulsion space under the piston and/or the charging port, and the charging channel has a dose opening connecting the charging channel with a dose space above the piston.
