Abstract

The actuator has a plunger (14) integrated and coaxial to an actuating rod (13). The rod is adjusted in a magnetic field frame (28) with less gap providing a mechanical guiding in one direction to prevent the plunger from sticking on one of two permanent magnets (24, 25). The rod is adjusted in the frame with a large gap in another direction, passing before the surfaces of the magnets in order to tilt the rod.
