ABSTRACT:
The present invention is directed to a solenoid valve for controlling a fuel injector in an internal combustion engine, having an electromagnet, an armature having an armature pin which is movably supported with respect to the electromagnet, and an armature plate supported on the armature pin in a manner allowing sliding movement, and a control-valve member moved together with the armature and cooperating with a valve seat to open and close a fuel discharge passage, the armature plate, in response to the control-valve member striking the valve seat during the closing of the solenoid valve, being able to be moved, under the influence of its own inert mass, along the armature pin along an overtravel distance, from a stop secured to the armature pin up to a stationary overtravel stop. To avoid post-oscillations of the armature plate on the armature pin when closing the solenoid valve, the armature plate is supported on the armature pin between the overtravel stop and the stop secured to the armature pin, in a manner that is free of returning elastic spring forces and allows sliding movement.
