The metering valve (1) for dispensing an aerosol has a metering chamber (10) and a valve rod (13). The valve rod (13) is provided with an end located at a reservoir and a dispensing end (12) and is mounted so as to slide in the metering chamber (10) under the effect of a spring (11) between a first, top position, called the rest position, and a second position, called the intermediate position for filling the metering chamber (10). The final, bottom position is defined by the lower end of the valve rod (13) being brought into abutment against the bottom of the valve body (7), the bottom of the valve body (7) having a shape (100) for axially centring the valve rod (13). |
