| 20100008009 | BISTABLE ELECTROMAGNETIC ACTUATOR, CONTROL CIRCUIT OF AN ELECTROMAGNETIC ACTUATOR WITH DOUBLE COIL AND ELECTROMAGNETIC ACTUATOR WITH DOUBLE COIL COMPRISING ONE SUCH CONTROL CIRCUIT - A bistable electromagnetic actuator comprising a magnetic circuit comprising a magnetic yoke in which a shunt extends perpendicularly to a longitudinal axis of said yoke and comprising a permanent magnet positioned between a first surface of the yoke and the shunt. A plunger core is fitted with axial sliding between a latched position and an unlatched position. A coil extending between the shunt and a second surface of the yoke is designed to generate a first magnetic control flux to move the plunger core from an unlatched position to a latched position. A second magnetic control flux enables the plunger core to move from the latched position to the unlatched position by the action of a return spring. | 01-14-2010 |
