发明名称 Hard coating of an impact surface of a solenoid actuator and fuel injector using same
摘要 A fluid control valve assembly controls the flow of actuation fluid to and from a fuel injector. The fluid control valve assembly includes at least one solenoid actuator attached to a valve body. The solenoid actuator includes a stator and an armature comprised of a soft magnetic material. At least one of the armature and the stator include an impact surface. The impact surface is coated with a relatively hard, nonmagnetic material coating. Thus, the relatively hard, nonmagnetic material coating will protect the relatively soft, magnetic material comprising the stator and the armature, and increase the durability of the solenoid actuator and the fluid control valve assembly.
