摘要： In an electromagnetic operating mechanism for a gas exchange valve of an internal combustion engine wherein two control magnets are arranged in spaced relationship above the valve and an armature is axially movably disposed between the control magnets and and actuator rod extends from the armature through one of the control magnets to engage the valve, two compression springs are arranged outside the control magnets in opposition to one another, one engaging the valve so as to bias it toward a valve closing position and the other engaging the actuator rod so as to bias it into a valve opening direction and into engagement with the valve.

摘要： A device for electromagnetic actuation of a charge change valve for internal combustion engines has an actuator unit that cooperates with the charge change valve and is arranged in a cylinder head of the engine. The actuator has an armature and two switch magnets located on either side of the armature, with the switch magnets holding the charge change valve in an open or closed position. The actuator unit is mounted to float in the cylinder head, with a play-compensating device with a play-compensating piston having a first and second pressure chambers being provided on or in the side of the actuator unit facing away from the charge change valve. The first pressure chamber is controlled as a function of engine pressure and the second pressure chamber is connected by a check valve with the first pressure chamber. Pressure medium can be drained from the second pressure chamber through a throttle line between the play-compensating piston and a cylinder surrounding said piston.
