FIELD: heating.
SUBSTANCE: invention refers to a fuel atomiser. Fuel atomiser (10) for fuel injection to combustion chamber (11) in an internal combustion motor primarily for common rail system is described, featuring valve element (27) controlling injection, travelling between closed position and open position where it opens atomising orifice system (25), and controlled by solenoid armature system (49; 80) via connective cavity (70) filled with pressurised work medium. According to the invention, solenoid armature system (49; 80) features at least two armatures (55, 55a, 55b, 56, 56a, 56b, 81, 86, 92, 94, 95, 97, 101, 108, 108a) moving against each other and protruding to connecting plane (70) by their end surfaces (65, 65c, 66, 66c).
EFFECT: distribution of force transferred by solenoid coil to solenoid armature system among both armatures so that the first armature performs mostly lifting of valve element controlling injection from its seat while the other armature ensures rather long required travel of valve element controlling injection.
