ABSTRACT:
A soleniod operated valve has an operating rod attached to the armature with one end of the rod contacting the end of a valve member for effecting movement thereof upon coil energization. A lower bearing is disposed in a lower flux collector adjacent one end of the rod. An upper bearing surface is disposed on an adjustment member threadedly engaging an upper flux collector with the armature return spring between the armature and upper bearing for maximizing bearing separation and improving armature alignment and reducing hysteresis.
