Abstract (en)

[origin: WO2006039922A2] The invention relates to a hydraulically actuated casting unit comprising a casting cylinder, whose chamber, which is active in the extension direction, is supplied with a hydraulic medium via a volumetric-flow controller during a pre-filling phase. An annular chamber, which is active in the retraction direction, is connected to a hydraulic-medium sink via a butterfly-valve assembly, which determines the pressure in the annular chamber. The invention also relates to a method for controlling a casting unit of this type.
