| description | The invention relates to an electromagnetic metering valve (34), in particular for an SCR metering unit (100) for the after-treatment of the exhaust gas from an internal combustion engine (155). The valve (34) comprises an electromagnet (158) having a cylindrical magnetic coil (167), an inner, substantially hollow cylindrical and an outer, substantially crucible-shaped iron yoke (66, 68) and an annular or disk-shaped armature (159) for actuating a closing mechanism of a valve nozzle (101) which, at an axial end of the electromagnet (58), can close and open the magnetic circuit between the inner and outer iron yoke (66, 68) in axially displaceable manner. The armature (159) is guided by an armature seat (52), wherein the armature seat (52) is resiliently mounted and guided in the direction of the electromagnet (58) by a spring element and in the direction of the valve nozzle (101) by a centering element. The invention further relates to an SCR metering unit (100) having such a metering valve (34) and to an exhaust gas after-treatment device (10) for an internal combustion engine (177), in particular for a drive motor of a vehicle which comprises such an SCR metering unit (100). |
