Abstract
An actuator includes a housing with a first end, a second end opposite the first end, and a bore disposed therein. The bore defines a poppet movement axis and extends between the first end and second end of the housing. A solenoid is disposed within the bore and extends about the poppet movement axis. An armature is disposed within the bore and is movable along the poppet movement axis between a disengaged position and an engaged position, the engaged position proximate the solenoid and the disengaged position spaced apart from the solenoid. A magnet is disposed within the bore between the first end of the housing and the armature, the magnet magnetically coupled to the armature to bias the armature towards the disengaged position.
