Abstract (en)
[origin: EP1672225A2] The arrangement has a direction control valve (14) forming a metering orifice. The control valve is attached to an individual pressure scale (12) for keeping the pressure constant over the orifice. The scale is switched into a locking position in a predetermined operating condition of the load. A pilot valve (13) subjects a control surface of a control piston with the pressure from a pressurizing medium source for switching the scale. An independent claim is also included for a method for controlling a double acting consumer, in particular, a hoisting gear of a mobile implement.
