Abstract: Metering valve for dispensing a fluid product, having a valve body containing a metering chamber, the metering chamber defined by a chamber insert and two O-rings, a valve stem seal and a chamber seal. The chamber insert has a cylindrical wall, an upper edge that cooperates with the valve stem seal and a lower edge that cooperates with the chamber seal, a valve stem sliding axially in the valve body between a rest position and a dispensing position, to selectively dispense the contents of said metering chamber. The said valve stem is urged towards its rest position by a spring that cooperates, on the one hand, with the valve body and on the other hand with the valve stem. The upper edge of the chamber insert has an opening connecting the metering chamber to an external volume arranged outside the chamber insert, between the valve body and the cylindrical wall.
