Abstract
An electromagnetic regulating device with a movable actuator (42), especially a piston, having an engagement region (44) on an end thereof, and a coil device (34, 36), which is stationary relative to the actuator and which is designed to exert a force on the actuator. The electromagnetic regulating device is provided with permanent magnet means, through which the actuator (42) is held to the coil device (34, 36) in the inactive state of the coil device (34, 36) and wherein when current is applied 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.
Claims14
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.
