To adjust the stroke of a control element actuated electromagnetically by means of a spring-mass oscillating system for displacement engines and to enable a freer arrangement of the electromagnetic setting device in the housing, in particular in a cylinder head of a displacement engine, the movement of the setting device is transferred to the control element, in particular one or more lift valves or flat slide valves, by means of a mechanical or hydraulic transmission system whose transformation ratio varies. Furthermore, devices are provided to adjust with precision the equilibrium position of the oscillating system. The electromagnetic setting device can also be combined with an end position attenuator and with a hydraulic compensating element.
