Summary: | A method for manufacturing a solenoid valve or a fuel injector, including a sleeve, a valve needle situated inside the sleeve in a radial direction and guided so as to slide, a solenoid coil situated outside of the sleeve in a radial direction, a magnetic core situated inside the sleeve in a radial direction, and a magnet armature situated inside the sleeve in a radial direction, axially opposite to the magnetic core; the magnet armature being situated on the valve needle, the sleeve having a low wall thickness in a thin-walled region situated between the magnet armature and the solenoid coil, the thin-walled region strengthened by a reinforcing element for absorbing radial forces; and a method step, during which, the reinforcing element is deposited onto the sleeve, in the thin-walled region, in a radial direction, outside of the sleeve, using a molten bath or cold gas spraying method. |
