Abstract

A device for adjusting an armature stroke of an armature upon actuation of a magnet of an electromagnetic valve having a stop bush disposed in an axial guide relative to a main body of the electromagnetic valve and adjustable in its axial position relative to the main body of the electromagnetic valve, which stop bush forms a stop for limiting the armature stroke in an axial direction. A variable adjusting element with two threaded portions providing a variable thread pitch (P) and the same thread direction by which the position of the stop bush is adjustable. The first threaded portion engages a corresponding first threaded portion of the stop bush, and the second threaded portion engages a corresponding second threaded portion of the main body, and to an electromagnetic valve having a corresponding device, in particular for use in a fuel injector.
