Purge control solenoid valve with non-adhesion coating at low temperatures and method for manufacturing the same
Abstract:
A purge control solenoid valve includes a gas access body including an evaporation gas inlet, an evaporation gas outlet, and a path that connects the evaporation gas inlet and the evaporation gas outlet; a valve operation body including an armature coupled to the gas access body and performing a reciprocating motion in a direction in which the armature is brought into close contact with or separated from the path by a core that generates a magnetic force; and an armature top member being in close contact with or separated from the path due to the reciprocating motion of the armature to open or close the path. The armature top member has a non-adhesion coating formed on a top surface of a body thereof, and the non-adhesion coating includes a binder, graphite, polytetrafluoroethylene, and a crosslinking agent.
