  • Patent number: 11626265
    Abstract: A trip unit for a circuit breaker includes a magnetic flux transfer system that employs a permanent magnet(s) and solenoid(s) with a ferromagnetic core. The system generates an attractive force using a solenoid to counter the force of a reset spring and latch friction force when a tripping condition is detected. The generated attractive force together with an attractive force from the magnet attracts a yoke which in turn moves the yoke together with an armature to the tripped position. The system also retains the yoke and armature in the tripped position using the attractive force of the magnet when the generated attractive force is no longer being generated. The system further generates a repulsive force using a solenoid when a resettable condition is satisfied to counter the attractive force of the magnet thereby allowing the yoke and armature to move from the tripped position to the reset position.

  • Patent number: 11598442
    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.
