Abstract

Electromagnetic valve, particularly for controlling a fuel injector or for regulating the pressure of a high-pressure fuel accumulator, comprising a casing (2), an electromagnet (24, 25) formed of a yoke (24) and an electromagnetic coil (25) housed in the latter, and an armature (22) in one or more parts. An abutment disk (28) is provided between the transverse face of the armature (22) turned towards the yoke (24) and the transverse face facing the yoke (24), this abutment disk (28) being made of a magnetized or magnetizable material, particularly of a ferromagnetic material.
