Abstract
The invention relates to a controlling device for hydraulic consumers (10, 12) with at least one controlling valve (18) for controlling a supply pipeline (TReg) for the respective hydraulic consumer (10, 12) and with a tank return pipeline (TR0). Because the control valve (18) is connected to an additional supply pipeline (T0) and constructed as a priority valve in such a manner that the supply pipeline (TReg) receives priority preference of a fluid supply system over the priority of the tank return pipeline (TR0), a type of sensor circuit is realized which checks whether, in accordance with the load situation at the hydraulic consumer (10, 12), then is any need at all for a supply flow.
Claims10
A controlling device for hydraulic consumers (10, 12) with at least one control valve (18) for controlling a supply line (TReg) for the respective hydraulic consumer (10, 12) and with a tank return line (TR0), characterized in that the control valve (18) is connected to an additional feed line (TR) and is designed as a priority valve such that the supply line (TReg) acquires preference of fluid supply relative to the tank return line (TR0).
