Abstract

Abstract Translated from French Injecteur de carburant comprenant une bille (12) d'obturation qui est sollicitée par une bobine d'excitation (15) entourant un noyau (2) à l'encontre d'un ressort (13), qui tend à repousser la bille (12) contre son siège (14). Une pastille (27) en matériau magnétique de grande dureté interposée entre le noyau (2) et la bille (12) est sollicitée contre le noyau (2) par le ressort (13). La face (28) de cette pastille (27), orientée vers la bille (12), est recouverte d'une couche mince de matériau non magnétique. Fuel injector comprising a sealing ball (12) which is urged by an excitation coil (15) surrounding a core (2) against a spring (13), which tends to push back the ball (12 ) against its seat (14). A pad (27) of magnetic material of great hardness interposed between the core (2) and the ball (12) is biased against the core (2) by the spring (13). The face (28) of this patch (27), oriented towards the ball (12), is covered with a thin layer of non-magnetic material.
