ABSTRACT:
The solenoid valve of the present invention includes an armature with a protrusion and a plug nut with a recess for receiving the protrusion. The protrusion includes a polymer o-ring. The protrusion is configured such that it slides freely within the recess. The o-ring contacts the plug nut to prevent further motion of the armature toward the plug nut after the protrusion has entered the recess.
