Abstract: Metering valve having a valve body containing a metering chamber defined by a chamber insert and two annular seals, a valve seal and a chamber seal, the chamber insert having a cylindrical wall, an upper edge cooperating with the valve seal and a lower edge cooperating with the chamber seal, a valve sliding axially in the valve body between rest and dispensing positions. The valve is urged towards its rest position by a spring cooperating with the valve body and with the valve. The upper edge of the chamber insert has an annular cutout formed on the radially inner side of the upper edge so that the width of the upper edge in contact with the valve seal is the same, whatever the width of the cylindrical wall. The metering chamber has a variable volume, in particular between 35 and 65 ?l, defined by the axial dimension of the cutout.

Abstract: Metering valve for dispensing a fluid product, having a valve body containing a metering chamber defined by a chamber insert and two annular seals, a valve seal and a chamber seal. The chamber insert has a cylindrical wall, an upper edge cooperating with the valve seal and a lower edge that cooperates with the chamber seal. A valve slides axially in the valve body between a rest position and a dispensing position, so as to selectively dispense the contents of the metering chamber, the valve being urged towards its rest position by a spring that cooperates with the valve body and with the valve. The upper edge of the chamber insert has an annular cutout formed on the radially inner side of the upper edge, so that the width of the upper edge in contact with the valve seal is always the same, whatever the width of the cylindrical wall.
