Method for manufacturing a solenoid valve

摘要

A method is described for manufacturing a solenoid valve, in particular a fuel injector, the solenoid valve having a valve needle which is movably guided in the axial direction, a magnet core and an armature which is situated axially diametrically opposed to the magnet core, the armature being situated on the valve needle, the armature having a first base material and a first reinforcing element and the magnet core having a second base material and a second reinforcing element. The method has one method step. The first reinforcing element is applied to the first base material and/or the second reinforcing element is applied to the second base material during the method step with the aid of molten bath spraying or with the aid of cold gas spraying.

主权项

1. A solenoid valve, comprising:
a valve needle which is movably guided in an axial direction; a magnet core; and an armature situated axially diametrically opposed to the magnet core, and the armature includes two surfaces perpendicular to the axial direction: 1) a first surface facing the magnet core, and 2) a second surface facing away from the magnetic core; wherein:
the armature situated is on the valve needle and includes a first base material and a first reinforcing element;the magnet core includes a second base material and a second reinforcing element;at least one of: i) the first reinforcing element is applied to the first base material with the aid of one of molten bath spraying or cold gas spraying, and ii) the second reinforcing element is applied to the second base material with the aid of one of molten bath spraying or cold spraying; andthe first reinforcing element is situated on both the first and second surfaces of the armature.
