Claims
- 1. A method for sizing an armature guide protrusion of a nozzle holder of an electromagnetically actuatable injection valve, wherein the armature is disposed in a nozzle holder bore of the nozzle holder having at least one, partway encompassing interior guide protrusion within the nozzle holder bore, which comprises mounting the nozzle holder (18) with a step (38) on a nozzle holder retainer (97) having an axial bore greater than the nozzle holder bore, pressing a completely spherical, freely movable ball (96) through the nozzle holder bore (26) from a direction of a retaining shoulder (59) of the nozzle holder (18), and in a direction of the step (38) of the nozzle holder (18), so that only the at least one guide protrusion (42), extending at least partway around an inner surface of the nozzle holder bore, is opened out to a rated size substantially the same as the diameter of the ball.
- 2. A method for sizing an armature guide protrusion of a nozzle holder of an electromagnetically actuatable injection valve, wherein the armature is disposed in a nozzle holder bore of the nozzle holder having at least one, partway encompassing interior guide protrusion within the nozzle holder bore, which comprises mounting the nozzle holder (18) with a step (38) on a nozzle holder retainer (97) having an axial bore greater than the nozzle holder bore, driving a conically embodied mandrel (110) having a conical surface along its length into the nozzle holder bore (26), from a direction of a retaining shoulder (59) of the nozzle holder (18) in a direction of the step (38) of the nozzle holder (18), to such a distance that the at least one extending guide protrusion (42) is opened out to a rated size only by the conical surface of the mandrel (110) and is formed with a conical inner guide surface that guides an armature.
