MAGNETIC VALVE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to fuel injection devices of internal combustion engines. Proposed magnetic valve designed to control valve nozzle of fuel injection system is provided with needle and armature made for displacement under action of own inertial mass relative to intermediate part connected with valve element. Intermediate part is made in form of rod installed for sliding in guide sleeve fixed in magnetic valve overcoming resistance of pretension return spring in direction of closing of valve element. Damping device interacting with armature and fixed element and providing displacement of fuel ensures damping of transient vibrations of armature at dynamic travel. Invention precludes transient vibrations of armature plate and makes it possible to maintain required short intervals of operation of magnetic valve. EFFECT: simplified design. 9 cl, 6 dwg
