FIELD: engines and pumps.
SUBSTANCE: invention relates to production of motors, particularly, to ICE fuel injectors. ICE fuel injector to be used, first of all, in common-rail systems, incorporates at least one injection control valve to open or close at least one spray bore fitted in system body. Besides, it comprises at least one fluid control valve for control over injection control valve element displacement by varying the pressure in at least one control chamber. Said valve is equipped with electromagnetic drive with at least one coil and at least one armature. Said armature consists of at least one armature plate interacting with electromagnetic drive and at least of armature core displacing along said plate to control pressure inside armature core control chamber. Armature core is composed by armature sleeve fitted on armature plate to slide there along.
EFFECT: smooth operation of armature, decreased time intervals between fuel injections.
