Abstract

Ein hydraulisch betätigbares Ventil mit steuerbarem Hub, ins­ besonders Gemischeinblaseventil für Brennkraftmaschinen weist eine fest mit dem Ventilschaft (3) verbundene Anschlagflä­ che (12) auf. Es ist zur genauen Steuerung der Ventilöffnung eine motorisch über eine Rutschkupplung (14) angetriebene An­ schlagnocke (11) vorgesehen, die mit der Anschlagfläche (12) zusammenwirkt, wobei durch Verdrehung der Anschlagnocke (11) um einen vorbestimmten Winkel der maximale Ventilhub einstell­ bar ist und wobei die Anschlagnocke (11) auch in der geschlos­ senen Stellung des Ventils (1) in Berührung mit der An­ schlagfläche (12) bringbar ist.
