  • Method for starting an electromechanical regulating device especially designed for controlling the charge cycle in an internal combustion engine
    Patent number: 6308668
    Abstract: A method for starting an electromechanical regulating device especially designed for controlling the charge cycle in an internal combustion engine. The electromechanical regulating device has an actuating element and an actuating drive. The actuating drive includes a first electromagnet with a first coil and a second electromagnet with a second coil, an armature which can move between contact faces of the first and second electromagnets, and at least one restoring means which is mechanically coupled to the armature. To start the regulating device, the second coil is energized until a first predefined condition is fulfilled and then the first coil is energized from the time at which a second condition is fulfilled until the armature comes into contact with the contact face.
