Abstract (en)

[origin: EP0814238A1] The electromagnetic operating device (3) has an actuator housing (4) enclosing a valve operating rod (8), acting on the valve shaft (1') of the engine valve (1) via a hydraulic valve play compensation device (10). The latter has a dash-pot rod (9) between the valve operating rod and the valve shaft, displaced in the direction of the valve axis (7) relative to the base plate (4') of the actuator housing.
