Abstract: A filling head for a device having a valve with a valve shutter, the head having a body having a receiving space, a control member that slides in the body between rest and filling positions, the member having a channel that opens into the receiving space, a ring fixed to the member and cooperating with a spring disposed between the ring and the body, and a plate fixed to the body and a housing for receiving the valve, such that, in the filling position, the valve shutter opens into the receiving space. In the filling position, the receiving space is sealed off, having a first seal between the control member and the body, a second seal between the body and the receiving plate, and a third seal between the receiving plate and the valve shutter, the third seal cooperating with an external lateral wall of the valve shutter.

Abstract: Metering valve having a valve body (10) containing a metering chamber (20) defined by a chamber insert (40) and a top and a bottom seal. The chamber insert (40) has a cylindrical wall (49) with an upper edge (41) cooperating with the top seal and a lower edge (43) with the bottom seal. A valve shut-off element (30) slides between rest position and dispensing positions. The valve shut-off element is urged towards its rest position by a spring (8) cooperating with the valve body (10) and the valve shut-off element. The lower edge of the chamber insert forms a flange and has a downward axial projection. The bottom seal has an axial opening (225) accepting an axial projection (45) and passing through the axial opening. The rest position of the valve shut-off element is defined by contact between the axial projection and a part of the valve shut-off element.
