Abstract:
A solenoid valve having current dependent bi-directional force includes a stator with a channel. An armature is in the stator channel. The armature is movable in a first and second direction. A projection extends from the stator into the channel. When a low current is applied, a flux is generated such that it jumps from the projection to the armature and back to the stator. Thus, the armature is pulled in the first direction. As the current is increased, the projection becomes magnetically saturated and the additional flux as a result of increased current jumps from the stator, at a thinned portion, to the armature then back to the stator. This moves the armature in the second direction, opposite to the first direction.
