Abstract

Eine hydraulische Steueranordnung ist mit einer verstellbaren Druckmittelquelle (5) zur Ansteuerung eines hydraulischen Verbrauchers (2) mit einem Druckmittel ausgestattet. Außerdem sind eine Steuerelektronik (25) zur Ansteuerung eines Stellorgans (12,16) der Druckmittelquelle und ein Bremsventil (9), durch welches eine hydraulische Verbindung zwischen dem Verbraucher (2) und einem Druckmitteltank (3) drosselbar ist, vorgesehen. Das Bremsventil (9) ist durch eine elektromechanische Betätigungsvorrichtung (10) willkürlich ansteuerbar.
