Abstract
The internal movement of one embodiment of a sealed fuel level sender employs two magnets disposed diametrically opposite each other about a pivot. The actuator that is operated by in-tank fuel level has two magnets disposed diametrically opposite each other about the axis with one pole of each magnet of the actuator confronting an opposite pole of a respective magnet of the movement to provide the magnetic coupling for causing the movement to follow the fuel level while minimizing, and preferably substantially eliminating, cross thrust on the pivot. Pole pieces may be associated with the magnets in a further embodiment. Still another embodiment employs magnets to only one side of the pivot, but with pole pieces that reduce cross thrust.
