Abstract
A solenoid for a solenoid-actuated valve includes a coil, a flux tube, a pole piece disposed axially from the flux tube and encircled by the coil, a movable armature disposed in the flux tube and the pole piece, and a latch disposed between the flux tube and the pole piece to selectively latch the armature into at least one position.

A solenoid for a solenoid-actuated valve, said solenoid comprising:
- a coil;
- a flux tube and a pole piece disposed axially from said flux tube and encircled by said coil;
- a movable armature disposed in said flux tube and said pole piece;
- and
- a latch disposed between said flux tube and said pole piece to selectively latch said armature into at least one position.
A solenoid for a solenoid-actuated valve, said solenoid comprising:
- a coil;
- a flux tube and a pole piece disposed axially from said flux tube and encircled by said coil;
- a movable armature disposed in said flux tube and said pole piece;
- a mechanical latch disposed between said flux tube and said pole piece to selectively latch said armature into at least one position;
- and
- a movable release slide disposed between said armature and said flux tube and cooperating with said latch to release said latch from said at least one position to a released position.
