  • Patent number: 6047718
    Abstract: A solenoid valve having a coil, a pair of armatures including an inner armature slidable within a coaxial outer armature and the outer armature slidable within the coil, and a pair of valves. One of the valves is at or near the end of the outer armature extending from the coil, and the other valve is at or near an end of the inner armature extending from the valve-bearing end of the outer armature. Thus, both valves are at the same side of the solenoid valve assembly. When a magnetic force is applied by a current flowing in the coil, at least the inner armature is drawn in a direction into the coil so as to open the valve at its end. An increased magnetic field caused by increased current in the coil eventually results in the outer armature being drawn into the coil, thereby also opening the valve at the end of the outer armature. The valve is suitable for use in many fluid control applications, but is especially useful for control of gases and for control of intermittent gas ignition systems.
