ABSTRACT:
A solenoid valve is disclosed including a valve housing having a central bore and a valve seat, a valve element movable between an open position allowing fluid to pass through said valve seat and a closed position in sealing engagement with said valve seat, a valve operator for moving the valve element between the open and closed positions including a reciprocating armature plunger member extending through the bore and an armature secured to the armature plunger, and the valve seat when the valve element is in its open position without creating a path of leakage when the valve element is in its closed position. The armature plunger includes a threaded-end portion which extends from the valve seat for receiving a valve assembly which is provided with a top portion forming a sealing face and a bottom portion having a central opening adapted to receive the threaded end portion of the armature plunger. The valve stroke and locking mechanism includes a two-piece collet adjusting nut assembly having a collet nut which threadingly engages the threaded end portion of armature plunger and a closed end acorn cap which is pressed onto the collet nut creating an interference fit between the collet nut and the threaded end portion of the armature plunger due to the radial pressure exerted by the acorn cap.
