ABSTRACT:
A poppet valve assembly comprising a valve housing defining a chamber and first and second spaced apart flow openings enabling flow through the chamber, a valve seat surrounding one opening, a valving member comprising a valving element positioned for engagement with the valve seat and a stem element fixed to and projecting from the valving element, the valving element movable between an open position spaced from the valve seat for enabling fluid flow through the housing and a closed position engaged with the valve seat, a solenoid assembly comprising an armature movable with respect to the valving member and the valve housing, the solenoid having an energized condition wherein the armature is subjected to an electromagnetic force and a de-energized condition, a spring system reacting between the housing and the valving member and coacting with the solenoid assembly to control positioning of the valving member, and anti-adhesion structure operative to shed material bridging the valve seat and the valving member when the solenoid is energized and enable seating and unseating of the valving member.
