<p>An electrically controlled valve (100) having a mechanism for controlling a non-linear force is disclosed herein. An embodiment of the inventive valve has a retainer (44), a actuator tube ( 34), a coil (30) and a housing (38). A pole piece (12) is seated within the actuator tube. An armature (20) is disposed within the actuator tube adjacent to the pole piece. A conical gap (16) is defined between the pole piece and the armature. A washer (18), which may be flexible an non-magnetic, is disposed within the conical gap. The washer counteracts the effect of a non-linear magnetic force by providing a non-linear force in opposition. The result is that the flow of fluid though the valve as well as the valve pressure is stabilized, in contrast with the prior art. <IMAGE></p> |
