Abstract (en)
A metering device for dosing pressurized fluids, in particular an injection valve for a fuel injection system in an internal combustion engine, is disclosed in which the hermetic sealing between the fluid chamber (2) for the pressurized fluid to be dosed and the actuator chamber (9) is provided by an elastic element (10c). The elastic element (10c) is arranged in a compressed manner between a sealing seat (15) of the valve body (1) and a flange section (10b) of a metallic sleeve that additionally comprises a hollow cylinder section (10a) in hermetic rigid contact with the valve needle (4). <IMAGE>
