ABSTRACT:
An electrically operated actuator mechanism for remote locking and unlocking of a door. The moveable bolt is coupled to a solenoid armature for movement in a guide which is registered against the door in the closed position. The solenoid coil bobbin is stationary and the pole frame including a magnet, bolt guide and bolt are slidable thereon for locating the bolt guide against the door at installation. A spring biases the bolt into engagement with the door. Upon coil energization in one direction, the magnetic flux of the coil and magnet are sufficient to move the armature and retract the bolt unlocking the door. Upon de-energization of the solenoid coil the magnet holds the armature and bolt in the unlocked position. Upon subsequent re-energization of the coil in the opposite direction, the magnet flux is neutralized and the spring returns the armature and bolt to the locked position. The actuator is particularly suitable for automotive fuel filler access door locking/unlocking applications.
