MAGNETIC VALVE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines; fuel injection systems. SUBSTANCE: proposed magnetic valve designed to control valve nozzle of fuel injection system is provided with valve needle. Valve needle is opened and closed by magnetic valve including electromagnet, armature and valve element shifted by means of said armature and loaded by spring in direction of valve closing. Valve element engages with valve seat. Armature is split, consisting of two parts and includes armature plate fitted on armature rod for displacement relative to rod direction of valve element closing under action of its own inertia mass overcoming resistance of return spring. Part of hydraulic damping device provided on armature plate ensures damping of transient vibrations of armature plate at its dynamic travel. EFFECT: provision of accurately maintaining required short intervals of magnetic valve operation, reduced movable mass and residual vibrations of armature part. 6 cl, 3 dwg
