Zusammenfassung:	PCT No. PCT/DK92/00203 Sec. 371 Date Dec. 22, 1993 Sec. 102(e) Date Dec. 22, 1993 PCT Filed Jun. 29, 1992 PCT Pub. No. WO93/01417 PCT Pub. Date Jan. 21, 1993.A hydraulic system has a pump (1) with at least one load (4, 5) and accompanying bi-directional valves (8, 8a). A first comparator (A) establishes which motor line (6, 7) is carrying the higher load pressure. A second comparator (B) establishes whether the input-side motor line (6, 7) allocated a directional signal identifying the direction of the valve displacement is carrying the higher pressure or whether a load (4, 5) is being operated with negative loading. Depending on the result of the comparison, the load pressure signal (y1, y2) can be processed differently.
