Abstract

An armature arrangement for use in an injection device of a fuel injection system comprises an armature (30), one or more of vent holes (40) in the armature, a valve body (24) associated with the armature (30) and a cavity (42) in the armature (30). At least one formation (60; 60, 64; 66; 68; 70) on an upper surface (38) of the armature (30) allows enhanced fluid flow from the one or more vent holes (40) to the cavity (42) which, in so doing, reduces the effects of cavitation on the shot-to-shot variability of the fuel delivery.
