Abstract
Die Erfindung betrifft eine Betätigungsvorrichtung für die Ansteuerung eines hydraulischen Verbrauchers (10), wie eines Arbeitszylinders, mittels eines Fluidversorgungsstromes. Dadurch dass mittels einer Ansteuereinheit (48) der Fluidversorgungsstrom für den Verbraucher (10) derart angesteuert wird, dass eine gedämpfte Betätigung mit einem sanften Anfahrverhalten erreicht ist, kommt es grundsätzlich für einen hydraulischen Verbraucher zu sanften Beschleunigungen, die im Hinblick auf das stetige Geschwindigkeitsverhalten von einer Bedienperson als angenehm empfunden werden.
