Abstract:
1. A regulating device for an internal-combustion engine for cam shaft regulation, the regulating device comprising a movable actuator ( 42 ) with an engagement region ( 44 ) on an end thereof and a coil device ( 34 , 36 ), which is stationary relative to the actuator and which is adapted to exert a force on the actuator, a permanent magnet, which holds the actuator ( 42 ) in proximity to the coil device ( 34 , 36 ) in an inactive state of the coil device ( 34 , 36 ) and, upon application of a current to the coil device ( 34 , 36 ), the actuator ( 42 ) is released from the coil device ( 34 , 36 ), overcoming a retaining force of the permanent magnet means, wherein the engagement region ( 44 ) interacts with a corresponding regulating element of a cam shaft.
